Engaging patients in high-quality, compassionate health care

What is Functional Medicine?

As functional medicine pioneer, Dr. Mark Hyman states, “One disease, many causes. One cause, many diseases.” Functional medicine seeks to answer these questions:  “Where does disease come from?” and “What are the root causes of an illness?” The approach to answering these questions is very often unique with each patient.

Traditional American medical schools focus on diagnosing and treating specific disease states. Hence,  here in the United States, we are very good at keeping people alive, but often after a disease has developed without addressing its root causes. This paradigm is beginning to change.

Functional medicine looks beyond symptoms to discover underlying factors that may generate a specific disease. This approach is taking root in mainstream medicine.

As a family medicine physician with training in integrative and functional medicine, my goal is to bring an individualized approach to treating and preventing illnesses to promoting maximum wellness and quality of life. To find the disease’s progenitors, I investigate genetics, environmental exposures, lifestyle, and socioeconomic factors. I use these findings to create tailored treatment plans designed to optimize outcomes and keep my patients off of medications whenever possible.

Generally speaking, a functional medicine approach is a very personal, preferably long-term relationship established over the years between a physician and patient.
