We invite you to learn more about our team.

John Franklin Zwetchkenbaum, MD

Dr. John Zwetchkenbaum is the chief allergist and founder of AAPRI. He received his Bachelor of Science degree from Brown University, earned his medical degree from Boston University and conducted his residency at George Washington University Hospital. He also completed a fellowship in allergy and clinical immunology at the National Jewish Center for Immunology and Respiratory Medicine (now National Jewish Health).

Dr. Z has always worked to expand and share his expertise in allergy and asthma medicine. He published a book about the underlying causes of allergies, Allergy Free with Dr. Z. Inspired to think outside the box and take a more holistic approach to patient treatment, Dr. Z became certified by the Institute of Functional Medicine.

Dr. Z started the practice 28 years ago with 1 chart and 1 employee, fulfilling all the practice duties from doctor to receptionist. Today, he is proud to work with his dedicated staff to serve over patients all over Rhode Island and Massachusetts, with comprehensive allergy & asthma treatment at 3 locations.

I have lived with severe asthma, and I’ve seen how treatment and immunotherapy can improve symptoms and quality of life.  I can personally understand the patients’ frustrations, and I enjoy working with them to help them feel better.
