Dr. Eric D. Schultz, DO, MPH, is recognized as one of the best allergists, immunologists and MCAS physicians in TX, providing advanced care for patients with complex allergic, immunologic, and mast cell disorders. As a double board-certified specialist and member of the American Academy of Allergy, Asthma and Immunology, Dr. Schultz is a leading MCAS specialist in Texas with extensive expertise in mast cell activation syndrome and mastocytosis. His foundational mast cell research at Duke University Medical Center — conducted in collaboration with Dr. Rebecca Buckley (previous Chief of Allergy/Immunology, Duke) and Dr. Michael Gurish (Harvard) — investigated mast cell homing, c-kit/SCF signaling, airways hyper-reactivity, and lung remodeling, establishing him as a nationally recognized mast cell expert.  His leadership as co-founder of Greater Austin Allergy, Asthma and Immunology, positions him as a top allergist in Texas and a trusted referral destination for patients across multiple states.

Based in Austin, TX, Dr. Schultz collaborates with major institutions including MD Anderson Cancer Center and serves in academic roles with The University of Texas Dell Medical School and Texas A&M College of Medicine, where he consults on Post-Acute Sequelae of SARS-CoV-2 (PASC/Long COVID)–related immune dysfunction and contributes to cutting-edge national research. With a high-volume, comprehensive practice offering biologic therapies, immunoglobulin replacement, and allergy immunotherapy, he is widely regarded as a leading immunologist in Austin and across Texas, and a top choice for patients searching for an MCAS specialist or allergist near them in Texas.

Dr. Schultz is a devoted husband and father of three children. He enjoys swimming, surfing, camping, and watching his kids play sports. His approach to patient care is to listen to the patient, provide peer-reviewed data, discuss possible diagnoses and treatment options, and establish a well-defined plan.
