Sally discovered Functional Medicine in 2009 after reading Dr. Mark Hyman’s book: The Ultra Mind Solution. “Dr. Hyman described everything I was trying to do within the conventional model.

Reviews
“Excellent experience with Dr. Foss!”
“I had the opportunity to see Dr. Foss twice while I was on the cape. I’ve had significant chronic back pain that has worsened over the last year and a half. My two appointments involving acupuncture and cupping were fantastic and I could feel the improvements. It was a great experience and I wish I lived here where I could receive treatment more regularly. Highly recommended.”
