Environmental Health & Allergy Center St. Louis is a medical practice with a differentiated approach to understanding and treating chronic illnesses. We identify and treat the underlining causes of chronic illness such that patients can reduce their reliance on medications that simply mask symptoms.

The illnesses we commonly treat are asthma, hay fever, sinus problems, arthritis, colitis, digestive problems, chronic fatigue, fibromyalgia, depressionanxiety, OCD, hyperactivity in children and autism.
