Dr. Jennifer Kessmann speaks on Functional Medicine, an approach to medicine that has been around for a number of years. It began with Dr. Jeffery Bland's motivation to look at medicine in a different way.   Now the field of Functional Medicine is ever expanding and a center at the Cleveland Clinic  has opened its doors for care.  It is becoming more widely accepted and parts of functional medicine have been integrated into a wide variety of disiplines in medicine.
