Dr. Jim Harris, MD

Before effective treatments were available for Cystic Fibrosis (CF) and the disease was still considered a fatal childhood diagnosis, Dr. Harris dedicated a significant amount of time and energy to care for children with CF. Since then, Dr. Harris has predominantly specialized in the treatment of commonly recognized conditions like allergies, sinus disease, asthma, eczema, and hives. However, after he started noticing a dramatic rise in cases that didn't fit within these typical immunological categories, he shifted his focus to these new presentations which are now known as Mast Cell Activation Disease (MCAD).  From MCAD, his focus expanded to include the co-occuring conditions of Mast Cell Activation Syndrome, Ehlers-Danlos Syndrome (EDS), Postural Orthostatic Tachycardia (POTS). After realizing that his patients were often unable to get care elsewhere for these conditions, Dr. Harris decided to dedicate his life to helping patients with EDS, MCAS, and POTS.
