Ramuel Holgado OnPoint Client
OnPoint Nutrition has been absolutely fundamental in helping me build lifelong dietary habits. I am much more conscious of the nutrition that goes behind my meals and most importantly for me, the portion sizes of the different foods I consume. The program is built in a sustainable manner in which you don't have to necessarily cut out any foods in your diet that you don't want to. 
Jennifer Newton OnPoint Client
The OPN team helped get me setup with an awesome nutritionist that worked with my personality and I have been working with her ever since. I love the non-diet mentality and the fact that all food is good - there are no bad foods, this is all about moderation. With my nutritionist's help I was able to balance out the food I was eating which led to better gut health, more energy and overall feeling better.
