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 newly recognized 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.

Since then, Dr. Harris has treated thousands of patients with thse conditions, and he has helped to educate the broader medical community through public presentations. He has also spoken at international conferences on these conditions including at the annual conferences hosted by Dysautonomia International and The Ehlers-Danlos Society. He spends a significant amount of his training other providers to help improve patient access to care.

Dr. Harris completed his medical education at the University of Iowa College of Medicine including a residency in Pediatrics and a fellowship in Allergy & Immunology. Dr. Jim Harris, M.D., is board certified in Pediatrics as well as Allergy and Immunology, and he has decades of experience in the field of clinical medicine. He founded the Center for Research at the South Bend Clinic, and he has conducted nearly 300 research studies, including research on Xolair, an important MCAS therapeutic.

Dr. Harris primarily serves as an educator and advisor for our clinical team, but he also provides medical care for patients in multiple states. Dr. Harris is currently able to provide medical care to patients who are physically located in Michigan, Ohio, Indiana, Texas, Colorado, Oklahoma, and multiple other states.

Reviews

"Dr. Harris has been one of the best doctors I have ever seen. He listened to me and my symptoms. He didn't just pass me along, he actually heard me. I feel truly lucky to have had been referred to him." - Kim

"Dr. James Harris is one of the few doctors to understand and treat autonomic autoimmune disorders. He has been so useful in my day to day ability to do normal stuff, like be out of bed. He deals with symptoms head on." - Mishelle

"Dr Harris identified a problem that we have searched for years to understand and it wasn’t EDS related, but is so helpful for my son to have relief." - Heather

"I’ve gotten so used to being dismissed by doctors for the past couple decades never getting to the root of my issues and just masking it with more prescriptions. With my first visit Dr Harris spent an hour(a whole hour!) with me discussing everything that I’ve been dealing with and diagnosed me with hEDS, MCAS and POTS. With the recommendations he gave me I have been feeling so much better than I have in years. I have felt so helpless for so long so it’s nice to feel validated knowing it wasn’t all in my head. Thanks you for helping me feel better!" - Amber

"Words can't even express how thankful I am for Dr. Harris. He is truly the Best doctor. He dedicates his life to helping others and even doing research on Mast Cell on his time off. He always takes the time to truly listen and involve the patient with their own treatment plan. I do not know where I would be if he did not diagnose and treat my Mast Cell along with my children. I now have hope." - Anonymous Patient

"Dr. Harris is literally the best doctor I have ever encountered. Aside from the obvious fact that his treatments have saved my life, Dr. Harris is one of a kind in that he listens." - Shane
