Britney Kennedy
Founder, CEO

Britney became interested in health and nutrition in her early teens.  Dancing from an early age, it was extremely important to eat a balanced diet to now perform at a pre-professional level.  Her interest in nutrition led her to The Pennsylvania State University to major in Nutritional Science.  After graduating in 2010 with a B.S. in Nutritional Science, Britney began helping individuals learn about nutrition, set goals, and lose weight.  Britney also holds a Graduate Certificate in Public Health from The Pennsylvania State University.

Since opening in 2015, Britney and her team of Registered Dietitians and Nutritionists have helped over 2,000 clients reach their health and nutrition goals  As the founder, it is her personal and professional mission to provide sound nutrition advice, rooted in scientific research.  OnPoint’s client centered approach allows for a greater understanding of clients’ needs, ultimately resulting in an improved quality of life. 

How did you get started doing this type of work?
Each member of my team was drawn to health and wellness from a different perspective. We are dancers, athletes, and chefs. We are mothers, daughters, and sisters. We are teachers, coaches, and listeners. Above everything else, we have a passion for helping you and improving your quality of life. We know that there are countless fad diets and misinformation on the internet. We want to help debunk the myths, teach you about healthy eating, and work with you to develop healthier habits.
How does OnPoint differ from other counseling programs?
All of our work is done virtually on a one-on-one basis. Clients virtually meet (video chat) with their nutritionist twice per week to assist with proper meal planning and to learn the fundamentals of nutrition. Our goal is to provide clients with the tools to make long term changes that they will be able to sustain long after working with us. We focus on each client's needs on an individual basis, helping to problem solve difficult situations and events.
What is the most rewarding part of your job?
The most rewarding aspect of my job is seeing the growth and success of our clients, and also my team!
Emily (Pierce) Horstman RD, LDN
Lead Registered Dietitian

Emily's passion for nutrition began in her teens. She started reading health and nutrition magazines which exposed her to fun tidbits about the power of food (shout out to Women’s Health, Shape, and Self!). The spark was ignited! As soon as she started visiting colleges, she never looked back. Emily completed her Bachelor's degree in Nutrition Management with a minor in sociology at Rochester Institute of Technology in Rochester, New York in 2013.  She then completed her dietetic internship at Miami Valley Hospital in Dayton, Ohio.

Before joining OnPoint, Emily worked full time as a clinical dietitian in long term care and medical rehab. She also worked at a cardiac rehab program instructing weight loss and wellness classes. Emily lives in New Jersey with her husband Stuart and her two cats, Jane and Beans. She has chickens, a garden, and strives to eat local as much as possible. She hopes to be a full blown homesteader one day! She enjoys weekend getaways, running, yoga, and has way too many magazine subscriptions. Her favorite foods are peanut butter and curries of all varieties.

What do you like most about being a nutritionist/dietitian?
I get to do something I love every day. There are always new findings and breaking research in the field of nutrition, so I am always expanding my knowledge base. I find it exciting and rewarding to be part of such an important aspect of my client’s health.
What questions do clients most commonly ask you? What is your answer?
I often get asked about quick weight loss and fad diets. As a nutrition professional, fad diets terrify me! They often set people up for a low calorie, deprivation riddled crash. I love teaching people that health is about life style, and not a quick fix.
If you could give clients one piece of advice in improving their health/nutrition, what would it be?
Keep it simple, eat whole foods.
Ivy Eliff

Ivy’s interest in food and nutrition started at a very young age; her father owned a health food store in the late ’70’s.  Living in a healthy household much different from most of her friends, Ivy considers her family’s “different” lifestyle a blessing.  In high school, Ivy attended a guest lecture opening her eyes to the immense world of nutrition. Intrigued, she moved on to attend West Chester University of Pennsylvania, earning a Bachelor’s Degree in Nutrition and Dietetics with a minor in Contemplative Studies in 2016. 

Ivy’s career began working for the USDA funded supplemental food program known as WIC.  Her counseling focused on working one on one with low-income, nutritionally at risk pregnant and postpartum women and children under five years old. Before WIC, Ivy spent years in the food service industry where she learned skills and techniques to use in her own kitchen. She has a passion for cooking, organic farming, and is a certified yoga instructor.

What do you like most about being a nutritionist?
Being a nutritionist gives me the ability to share my knowledge with those in need. Food is essential for daily life.  When you learn what foods you should be eating to fuel your body to the best ability, the possibilities are endless.
What questions do clients most commonly ask you? What is your answer?
“What foods should I avoid?” To this, I always say, stay as far away from processed foods as you can. Of course, it’s extremely difficult to avoid these products at all costs.  The more conscious choices we make to consume products with the most natural ingredients, the more our bodies will thank us. 
If you could give clients one piece of advice in improving their health/nutrition, what would it be?
Stop eating out and spend more time experimenting in your own kitchen! Life has become so fast paced that we often forget how essential cooking at home is for our health. Constantly eating out or grabbing a quick freezer meal causes us to not only overeat, but to consume foods oblivious as to what is in them or where those ingredients came from.
Zoe Fienman RD, LDN, CDE
Registered Dietitian

Zoe obtained her Bachelor of Science in Nutrition and Dietetics with a minor in Psychology from West Chester University of Pennsylvania in 2013. Zoe’s commitment to nutrition started after registering for an elective nutrition course.  She instantly became fascinated by the science of the subject. After graduating, she completed her Dietetic Internship with Aramark and successfully passed the Registered Dietitian exam in August of 2014.  Zoe is also a Certified Diabetes Educator, with extensive knowledge of and experience in diabetes prevention, prediabetes, and diabetes management.

Before joining the team at OnPoint Nutrition, Zoe started her career at a weight management center, helping clients achieve weight loss goals ranging from 10-200 pounds. Looking to expand her experience, she took a position at Holy Redeemer Hospital as both an inpatient and outpatient Clinical Dietitian.  Her passion is motivating clients to meet their health and wellness goals.  After seeing positive results in her clients, it didn’t take long for Zoe to feel rewarded.

Zoe believes “a healthy diet is a diet that fits your lifestyle and is filled with an abundance of wholesome foods that are nutritious and flavorful!”  In her free time she enjoys spending time with her family and friends, running and biking through downtown Philadelphia.

What do you like most about being a nutritionist/dietitian?
I love the science behind nutrition and connecting food to how our body’s function. Optimizing your nutrition can make a huge difference on how you feel day to day. It’s the best feeling when clients can feel the difference after making positive diet and lifestyle changes.
What questions do clients most commonly ask you? What is your answer?
“What is a perfect diet?” My answer is always “It’s different for everyone, what works for you might not work for your neighbor or best friend. By working together through trial and error we’ll find YOUR perfect diet.
If you could give clients one piece of advice to improve their health/nutrition, what would it be?
Don’t beat yourself up. No one day or one meal can make or break all of your progress. Every change big or small goes a long way!
Brittany Linn RD, CDN
Registered Dietitian, Client Experience Specialist

Brittany is a compassionate dietitian with over 10 years of diverse experience in the wellness, coaching, and nutrition education world. She received her Bachelor’s of Science in Nutrition from The University of Delaware in 2013, completed her Dietetic Internship program through Long Island University Post, and passed her RD exam in 2015. Before joining the OnPoint team, Brittany was an clinical dietitian where she treated patients with chronic diseases, gastrointestinal surgeries, cancer, ICU patients, and many more while working in the hospital.

As she grew in her career, Brittany realized her true passion was to provide personalized one on one counseling to help individuals reach their health goals, both mentally and physically. Her ultimate objective for each person she works with is to teach them how to create lasting wellness habits and increase their confidence around food and within themselves. Brittany lives with her husband Ben, who she met when she was 12 years old at overnight camp, she also loves to teach spin classes in her free time, and enjoys eating her favorite foods, which are soft pretzels, carrots, and ice cream (with sprinkles!).

What do you like most about being a dietitian?

I love teaching people that living healthfully can be easy and even fun! I also enjoying showing people the power they have over their own wellbeing, and that they can successfully stay healthy without following a trendy fad diet or living a life of endless yo-yo dieting.

What questions do clients most commonly ask you? What is your answer?

I often get asked about what time people should stop eating or if it’s okay to eat certain foods at night. My answer is this: If you are hungry at night you should eat, especially if you haven’t eaten enough in the day. If you find yourself habitually snacking after the point of fullness at night, there are certainly other things to look at besides food (a.k.a stress and other habits). Additionally, eating too close to bedtime can disrupt your sleep and even cause GERD. So, if there’s a way to fill up with nutritious foods during the day rather than at night, it’s best to plan ahead for that!

If you could give clients one piece of advice to improve their health/nutrition, what would it be?

Make friends with your body. It will be your greatest ally when making changes that will benefit your health in the long run.

Morgan Fereck MS, RDN, LDN, CPT
Registered Dietitian

Morgan's passion for nutrition started at a young age as she was interested in her family’s health and helped her diabetic dad by influencing her family’s eating habits. She later completed her Bachelor's Degree in Nutrition and Dietetics and Dietetic Internship from Marywood University in 2013 and Masters of Human Sciences (Public Health) from University of Alabama in 2015. 

Morgan’s professional experience began in a clinical setting as a Registered Dietitian working in rehabilitation and intensive care. Looking for a new challenge, she later joined the team at Lifetime Fitness as Registered Dietitian and Nutrition Program Coordinator, where she combined her love of nutrition with personal training. Her work focused on helping clients create healthier habits both in and outside of the gym by teaching a step by step approach to improving their nutrition and lifestyle.

Morgan is a vegetarian and loves finding new, healthy, and creative recipes to keep things interesting. She lives in New Jersey and loves spending weekends traveling. She was motivated to complete her first marathon last year and likes running and staying active as much as possible! 

What do you like most about being a dietitian?
I love teaching clients how to improve their health while having a great relationship with foods.  I also love educating clients about why we are choosing and recommending the foods we are  instead of following the latest trends. 
What questions do clients most commonly ask you? What is your answer?
"What is the fastest way to get to my long term goal?" I encourage clients to enjoy the journey and set small achievable goals to get to their long term goal.  We can celebrate mini success stories as we grow to that long term success.  That way the goals are long lasting instead of a “quick fix”. 
If you could give clients one piece of advice to improve their health/nutrition, what would it be?
We give ourselves too many rules when it comes to dieting and nutrition that we lose the excitement. When we have a good relationship with our food, our health and nutrition will improve which will help us enjoy this journey more.  
Shannon Gray MS, RDN, LDN
Registered Dietitian

Shannon has had a strong connection with food since she was a student-athlete at West Chester University. During her college career studying nutrition and dietetics while also playing softball, she realized the importance of using food to fuel and remain healthy. Her connection with food then developed during her time at Ohio University completing her dietetic internship and Masters Degree in Nutrition Sciences. As Shannon was struggling with chronic cystic acne, she realized the importance of using food to heal her body from the inside out. After adopting a whole foods plant based lifestyle, her body started to heal and she is now living with clear skin, a clear mind, and a strong relationship with food.

Shannon started her career working as a clinical dietitian in long term care and rehabilitation centers in the surrounding Philadelphia area. Shannon lives in Philadelphia and loves exploring the city and trying new restaurants. She loves to garden, take walks, exercise, cook, travel, and spend time with her friends and family.

Shannon is passionate about helping others on their health journey. She realizes the struggles, frustrations, and doubt that may come with changing lifestyle habits; however, she recognizes the reward and happiness it brings to people’s lives. She wants to be the support and empowerment for people on their very own health journey.

What do you like most about being a dietitian?

As a dietitian, I talk about food a lot. I love that food can mean so many different things for different people. Everyone can relate to food and I enjoy building relationships based on this concept. Food has the power to help people with so many health conditions, and I love being able to share my knowledge about food to help people every day.

What questions do clients most commonly ask you? What is your answer?

Clients most commonly ask me “what foods do I need to cut out,” or “what is the fastest way I can lose weight?” My answer is first looking at what foods can you bring in to your diet to help, then look at what do you comfortable on reducing and why. It is so important to understand the “why” so that you feel comfortable making your own decisions while keeping in mind your health goals. Because we are working on lifestyle changes rather than “diets,” any food can still fit into your lifestyle. Since this is a health journey where we work together to create a healthy lifestyle, most commonly weight loss is a positive side effect. Be patient and trust the process!

If you could give clients one piece of advice in improving their health/nutrition, what would it be?

Improving your health and nutrition will bring you many rewards in so many aspects of your life that you may not have even realized! Keep an open mind and focus on small positive changes to lead you to your ultimate goals. It can be hard sometimes but know that you will have a strong support system to keep you positive and motivated!

Kristin Shapiro RD
Registered Dietitian

Kristin graduated from Elon University in 2015 with a BA in Human Services. A few years later, she decided to go back to school to combine her passion for helping others with her interest in all things nutrition. She completed her didactic dietetics courses through LaSalle University, graduated from Aramark’s Dietetic Internship (completed at Virginia Hospital Center), and passed the Registered Dietitian (RD) examination.  Prior to joining the OnPoint team, Kristin worked as a clinical Registered Dietitian in a rehabilitation/long-term care facility.

Kristin grew up in a family of foodies and she loves all different types of cuisine. Throughout her life she has struggled with GI distress related to anxiety and poor eating habits. She quickly recognized the profound impact nutrition can have on the human body, especially when it comes to mental health. She is truly passionate about the power (and enjoyment!) of food.  

Kristin is a self-proclaimed research nerd and is fascinated with the cultural, physical, and emotional aspects of food. There is so much conflicting nutrition advice that exists.  Providing evidence-based knowledge is her priority! When she isn’t working with clients, she is a die-hard beach lover and Registered Yoga Teacher. She loves sewing in her spare time and hanging out with her miniature dachshund, Moose.

What do you like most about being a Registered Dietitian?
There are so many aspects of diet and nutrition whether it be social, cultural, emotional, or physical. I love to see the evolving research that comes out related to the field of nutrition and clarifying fad from fact!
What questions do clients most commonly ask you? What is your answer?
“Is _______ food bad?” My answer is typically “I don’t like to label foods as ‘good’ and ‘bad’ because all foods can be incorporated into the diet in moderation!”

Interested in working with Katelan? See what her clients have to say!

What do you like most about being a nutritionist?
My favorite thing about being a nutritionist is when I see a client take the knowledge I share with them and personalize it to fit their lives. I believe eating well oftentimes gets a bad reputation and can intimidate people. I enjoy having conversations with clients about what works best for them and changing any preconceived notions about foods.
What questions do clients most commonly ask you? What is your answer?
I would say most often people ask “What should I eat?” I answer that by telling clients to enjoy the foods they love with modifications to portion sizes and frequency. I want to see them take what they learn and put it into action!
If you could give clients one piece of advice in improving their health/nutrition, what would it be?
Nobody can be perfect! I would rather see my clients make progress from where they are. Every aspect in life is about balance and eating well should be no different. I’m here to show people how to balance their lives and to help them make choices they can feel good about.

What do you like most about being a nutritionist?

I love having the opportunity to meet new people from all over, relating to them through food, and educating clients on the importance of a balanced, healthy diet and how it can positively impact all aspects of their lives! 

What questions do clients most commonly ask you? What is your answer?

“Why is ‘diet’ food so boring and bland?” I always love getting this question because my first response is that is doesn’t have to be!  If you are utilizing proper portion sizes, using a variety of herbs and spices, and sticking to high quality ingredients, even your go-to unhealthy recipes can be transformed into a flavorful, nutritious option! I love seeing that “a-ha" moment in a client when they are able to use my suggestions to try new food, and create recipes they love. 

If you could give clients one piece of advice to improve their health/nutrition, what would it be?

Your journey to a new healthy lifestyle is a marathon not a sprint, be patient and remember small changes create big results!  

Kaitlyn Willwerth RD, CLT, MS
Registered Dietitian

Kaitlyn received her Bachelor of Science in Nutrition and Dietetics from West Chester University of Pennsylvania in 2017 and completed her Master of Science and Dietetic Internship from Ohio University in 2019. Kaitlyn adopted a healthy lifestyle after battling with gastrointestinal issues in high school. She decided to make her passion for healthy living into a career after taking a nutrition course during her first year of college.  

Prior to joining the OnPoint team Kaitlyn interned with the Diabetes Institute, leading their Diabetes Prevention Program in Athens, Ohio.  Her work focused on individualized health and lifestyle coaching, providing nutrition education and, most importantly, support.  Kaitlyn also previously worked as a Nutrition Educator delivering nutrition education curriculum to second grade students. 

Kaitlyn is also a Certified LEAP therapist, having completed advanced clinical training in managing adverse food reactions with an emphasis on food sensitivities.  She is well also versed in the low FODMAP diet as well as a variety of other diets to help improve quality of life.

In her free time, Kaitlyn enjoys spending time outdoors and doing activities like hiking, running, and fishing. When she’s not busy being active you can find her in the kitchen! She loves trying new recipes and cooking for her friends and family.
What do you like most about being a dietitian?

My favorite part about being a dietitian is being able to help people reach their health goals. I love the feeling when clients have that “aha!” moment where everything clicks. Most of all I think it’s really special to see how sharing my knowledge of food and nutrition with clients can help them feel motivated and empowered to take control of their health and reach their goals. 

What questions do clients most commonly ask you? What is your answer?

I get a lot of questions about fad diets- do they work, which one is the best, etc. My answer always will be that there is no short cut to weight loss. Fad diets commonly restrict certain food groups or force people to change their eating habits so dramatically that it is just not feasible long term. This is usually why people have a hard time keeping weight off after they try a fad diet. The only way to achieve true long-lasting results is to make realistic lifestyle changes. 

If you could give clients one piece of advice to improve their health/nutrition, what would it be?

One simple piece of advice I would give clients to improve their health and nutrition is to eat more fruits and vegetables. Fruits and vegetables have a wide variety of health benefits and are crucial for your body to perform its necessary functions. Also, if you are eating more fruits and vegetables, you will inherently be eating less foods that may not be as beneficial to your health.

Cathy Esibill RD, LDN
Registered Dietitian

Cathy has been a dietitian for 16 years and worked at Main Line Health for many years prior to coming to OnPoint Nutrition. She first received a Bachelor’s degree in Kinesiology from The Pennsylvania State University prior to studying Nutrition at LaSalle University. She completed her internship with ARAMARK in Philadelphia and passed her RD exam in December of 2004. She brings much experience having worked at various outpatient entities, ranging from obstetrics to weight management, throughout her career.

Cathy’s interest in Nutrition first began when she discovered the joy of cooking and sharing food with family and friends. She started cooking her way through Ina Garten’s cookbooks after college and considers her approach of using best quality ingredients to be the precedent to her preference for using fresh, local and organic ingredients whenever possible in the kitchen. Cathy teaches a diet free lifestyle full of plants and believes you can enjoy all your favorite foods in moderation.

Some of her happiest times are spent hiking in the Wissahickon, gardening, and spending time with her family every summer at the Jersey Shore.

What do you like most about being a dietitian?
The power of food is immeasurable. What we eat affects our thoughts, mood, energy levels and even feelings. I really enjoy helping people realize the power of food and how to enjoy eating rather then resenting it through proper, sound advice.
What questions do clients most commonly ask you? What is your answer?

“How do you eat so healthy, all the time? I couldn’t possibly live without (X) food?!” The answer to this is twofold. First, I don’t eat perfectly all the time. I live and teach a diet free lifestyle. I enjoy many foods that aren’t considered the most nutritious because I find pleasure eating them and have learned how to fit them into a healthy lifestyle. Secondly, I honestly really enjoy the healthy foods I eat! If you aren’t used to eating a variety of nutritious foods, allow yourself the time for your tastes to adjust and evolve; this is an important part of changing your relationship with food.  

If you could give clients one piece of advice in improving their health/nutrition, what would it be?

Stop comparing yourself to others! Your own best self is unique to you and the path to your healthiest you is a personal journey.
