"Dr. Michele and Dr. Mark Sherwood have helped me tremendously toward my goals. I highly recommend working with them. My friends are amazing and I know you’ll get incredible results.”

Your success is our success

We love to celebrate the everyday victories and life-changing breakthroughs of our patients. Are you ready to become another success story?

After a confrontation with diabetes, which I had avoided for 5 years, Dr. Michele encouraged me by saying, “We will save your life and you will be a beacon of health in your area.” It was at this time that I knew I was in the right place.

By doing all that Drs. Michele and Mark have helped me with, I’ve lost 20 pounds. I’m off blood pressure medicine. My menopausal symptoms are almost gone completely now. I feel so much better and way healthier.
