Jason Catanzaro, MD

Jason Catanzaro, MD, specializes in treating children with allergic disorders or primary immunodeficiencies, or when a patient’s immune system is not acting normal. These are usually caused by a genetic defect.

“I enjoy helping patients understand their condition and providing them with treatment options,” Dr. Catanzaro says. “What’s cool is helping kids feel better, whether it’s preventing or stopping infections or helping with allergies so they can play sports or enjoy the outdoors.”

Treatment options Dr. Catanzaro offers include allergy shots or immunoglobulin replacement therapy, a blood-based treatment to boost the body’s natural antibody levels and fight off infection. When it comes to reassuring patients, he tells them, “Every day is better than the last.”

Dr. Catanzaro’s research focuses on how gut microbiota (a collection of microorganisms including bacteria and viruses that live in the digestive tract) impact patients with primary immunodeficiencies.
