Functional Medicine Physician Endorsement
“I wholeheartedly endorse Heidi Cox as an extremely talented, and superbly educated, expert in personal fitness and coaching. She has a deep understanding of how the body works, and the real mechanics of facilitating personal, positive lifestyle changes. Those traits alone would make her a good investment. She is also a very effective communicator, demonstrates terrific integrity and is super positive. The way she approaches her work dovetails perfectly with the best practices and principles of functional medicine. My patients achieve optimal health much more quickly, and with fewer unnecessary detours, with a top-notch trainer like Heidi.”
Rob Downey, MD, IFMCPSeaworthy Functional Medicine, a department of South Peninsula Hospital
“Heidi is incredible. She’s been where I have been physically. She’s not only a health coach but a friend. I love that she pushes me when I need it and also lets me whirl as well! I’m so thankful for the time I have with her! Plus, I know if I want a Reese’s—she’s there to talk to me and sort “why” I need it. Thanks Heidi!”

“Heidi is amazing! She’s real, she’s encouraging and she’s a kind soul with a witty sense of humor that fits right in to fitness and nutrition and meeting your goals. Heidi was my trainer a few years back when I decided at age 38, I wanted to compete in my first fitness competition. I could not have got on stage and placed in not one, but two different categories, without her coaching and support!!”

“Heidi is amazing! She is well informed on both nutrition and fitness. She has been teaching fitness classes for several years and has a great program for building and toning muscle with your own body weight. She’s also a great coach for nutrition and weight loss. Heidi is very encouraging and understands the ups and downs we all go through on our nutrition journey. She works to meet you where you are to help you get where you want to be, taking small steps that can really produce change. She loves to solve the enigma of what will work for each individual person. I highly recommend her to anyone who wants to better their nutrition, tone muscles, and change their mindset!”

“With Heidi, you get what you give. If you give her your honesty about your goals, she’ll give you what you want and need, and a little more. Heidi was my weight loss and fitness trainer seven years ago. Heidi was more than a trainer to me though; she was also my therapist, nutritionist and cheerleader! She knew when to push me physically when I didn’t think I could. She thinks about the whole person; all their needs, strengths and weaknesses, and does a great job to give them the results they work to achieve.”

“Let me share with you about Heidi Cox. I had started with a trainer that was not very encouraging, and I was ready to call it quits. Then Heidi introduced herself and we talked. I liked Heidi right off. She listened to me, encouraged me, acknowledged and accepted my schedule, and before I knew it, we were working together and becoming fast friends. In the years she worked with me, we laughed, cried, hugged and sweated. A loving, kind, compassionate, hardworking, encouraging personal trainer.”
