Applying Functional Medicine in Clinical Practice addresses the key issues healthcare needs to address today – improving management of complex, chronic disease.

IFM programs utilize the emerging research base to identify effective interventions and to train physicians and other providers to integrate those approaches for the benefit of their patients.

Applying the fundamentals of functional medicine includes the understanding the etiology, prevention, and treatment of complex, chronic disease. It is an integrative, science-based healthcare approach that treats illness and promotes wellness by focusing assessment on the bioachemically unique aspects of each patient, and then individually tailoring interventions to restore physiological, psychological and structural balance.


Patient Testimonials

On March 10th we had our first appointment at Mountain Health Functional Medicine. We both joined Roy’s program, and we are so glad we did. Since March, Butch has lost 36 pounds, and I have lost 22 pounds. We are both sleeping better, eating better, feeling better, and enjoying life more.

We are learning about the importance of hormone balance, and both have had hormone injections just two weeks ago.

Together, we have decided to get off the conveyor belt to getting older and sicker, with more medication each year. We are fighting to stay healthy and active, and we now think getting to know Roy Hall has been a gift from God.

“I want to extend to you my heartfelt thanks. Thank you for being so positive — so upbeat about her condition. I felt doctors before you were doom and gloom. Everyone insisting it must be cancer or AIDS. You are the only one who gave us hope. You gave us something to work on — the Elimination Diet. This is life changing.”
