“I am happy to write a testimonial about Kerri Sherk, Registered Dietitian, Yoga Instructor and fitness director of The Fitness Firm.

Over the years, I have searched to find a person who could help me meet my diet and fitness needs and I have met with many people in the health and fitness related industry. Kerri offered a new approach. Specifically, her genuine, positive and supportive attitude stood out to me and she developed an individual plan that was right for me. She listened to what I had to say and incorporated my specific needs into a nutrition and exercise plan.

In the past, I have been on restricted diets and health routines but I never stuck to them. I was hungry and exhausted. I met some goals short term but long term I could not sustain the plan. I regained the weight and abandoned exercise. Then I would start again and the whole cycle would repeat.

Kerri has given me a life plan for food, exercise, and overall health. It is sustainable. I am not hungry. I don’t have cravings! In the past, I didn’t know if I was hungry, tired, or stressed. Meeting with Kerri for weigh ins, talks and review of my food diary helped me to know what is happening in my body. She is very motivating and there was no shame! I have even been on vacation and can make good choices while still enjoying a special treat.”


After gaining and losing weight most of my life, I decided 3 years ago to make a change. I found Kerri online and decided I would try a Dietician. Kerri was great, she was realistic and provided me with food plan ideas that were all about real food, not just expensive pills or vitamins, and was there for guidance whenever I needed it. With her help, I lost 30 lbs and have kept it off for 2.5 years”
