What is Functional Medicine?

Functional Medicine is transforming healthcare by giving the patient the ultimate power to heal. Functional Medicine efforts focus on the root causes of an individual’s condition and treats those causes.

We believe that by studying the individual and his or her interactions with their environment (exercise, toxic exposures, sleep patterns, diet, stressors, mental health, and history of disease or dysfunctions), we are better equipped to help our patients achieve improved health and wellness. Our philosophy for optimum health is based on our belief that everyone has the potential to achieve wellness.
