About Me

Ryan Maciel, Registered Dietitian & Strength and Conditioning Specialist

Ryan Maciel, RD, Pn2, CSCS

I believe that achieving good health shouldn't be complicated. Everyone is unique, and there is no one-size-fits-all approach.

I meet my clients where they are and collaborate with them to craft a plan that is easy to follow yet effective in meeting their needs and goals.


I provide my clients with the guidance, support, and accountability to help them build sustainable healthy habits to improve their health.
