About Me

Before joining Summit Health, Medical Research Chair Gary Pien, MD, PhD, FAAP, FAAAAI, was an Attending Physician in the Division of Allergy and Immunology at Children's Hospital of Philadelphia, Pennsylvania. In addition to his position with Summit Health Allergy, Dr. Pien is an allergist and immunologist at Overlook Medical Center in Summit, New Jersey. His expertise includes pediatric allergies, immune deficiencies, and recurrent infections. The American Board of Allergy and Immunology and American Board of Pediatrics certify him in allergy/immunology and pediatrics, respectively.

A sought-after speaker, Dr. Pien has delivered local, regional, national, and international invited presentations concerning immunology. He recently appeared on the NBC Today Show, where he discussed practical aspects of food allergies. Dr. Pien's research interests include new diagnostic approaches and treatments for asthma, food allergies, and anaphylaxis as well as new diagnostic testing and management of immune deficiencies. He is the author or coauthor of articles and abstracts concerning these and related topics, which are published in prestigious, peer-reviewed scientific journals such as Journal of Clinical Investigation, Journal of Immunology, and Annals of Allergy, Asthma, and Immunology. Dr. Pien is a fellow of the American Academy of Pediatrics, American Academy of Allergy, Asthma, and Immunology, and American Contact Dermatitis Society. He is a former member of the American Association for the Advancement of Science, Pennsylvania Allergy and Asthma Association, and American College of Allergy, Asthma, and Immunology.

Dr. Pien is the recipient of 18 honors and awards, including the American Association for the Advancement of Science Excellence in Science Award and Hasbro Children's Hospital Excellence in Pediatric Emergency Department Award. The Consumer Research Council of America lists him among "America's Top Pediatricians," and he has been featured in the New Jersey Monthly "Top Doctors" listings.

Dr. Pien notes, "I'm committed to staying abreast of and applying leading-edge medical research to daily practice. My practice philosophy includes tempering high-tech medical science with practical knowledge and good sense to deliver the best possible care to my patients. It is in partnering with my patients that I can best help them achieve their health goals."
