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.

Emily (Pierce) Horstman RD, LDN

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 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!

Morgan Fereck MS, RDN, LDN, CPT

Registered Dietitian

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.

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 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!

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.

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.

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.

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 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 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.
