Functional Medicine

Rather than targeting individual symptoms, functional medicine focuses on the optimal functioning of the entire body and its organ systems. It addresses the underlying cause of disease, using a systems-oriented approach in partnership with understanding the conditions and history in which the disease manifested. Genetic, environmental, internal, emotional, physical and lifestyle factors all play a direct role on long-term health and chronic health issues.

Dr. St Jean strives to help you recover your health quickly and with minimal fiscal impact. As the integrative and functional health field continues to become overly costly and involve unnecessary testing and treatment, Dr. St Jean ensures his model is not based on dogma and instead on sound science.
