A firm believer in a holistic approach to medical care, Dr. Smith focuses on lifestyle medicine. He understands that food and exercise have the ability to minimize the need for medication - and even heal. His conviction became even stronger after he significantly improved his own auto-immune condition with intensive lifestyle therapy and medication. What does he like best about being a doctor? He thoroughly enjoys helping people and getting to know his patients, building a trusting relationship with them and making treatment decisions together based on goals, lifestyle and health needs.
