Dr. John R. Sweeney Jr.

Dr. John R. Sweeney Jr.

Dr. John R. Sweeney Jr, graduated from Vanderbilt Engineering School Magna Cum Laude in 1972 with a degree in Biomedical Engineering. He graduated from Vanderbilt Medical School in 1976 and completed a pediatric residency at the Naval Hospital, Portsmouth, Va, in 1979. He practiced general pediatrics in the Navy for five years and developed an interest in diseases of the immune system. He subsequently entered a fellowship in Allergy and Immunology at Children’s Hospital in Cincinnati (affiliated with the University of Cincinnati) and completed the fellowship in 1986. He then returned to the Naval Hospital and created the Asthma and Allergy Clinic, which served both pediatric and adult patients. He ran both of these clinics until his retirement from the Navy in 1996. He has been in private practice in Suffolk and Portsmouth since that time. He was the only board-certified allergy and immunology doctor providing care to both adults and children in Portsmouth, Western Chesapeake, and Suffolk until being joined by Dr. Thamiris V. Palacios-Kibler in 2017. 

Dr. Sweeney is a widower whose wife died when his three children were very young, all while maintaining a successful allergy practice and taking good care of his patients. He raised his children as a single father and now has six grandchildren.

Dr. Sweeney is Board certified by the American Board of Pediatrics and the American Board of Allergy and Immunology, a Conjoint Board of the American Board of Internal Medicine and the American Board of Pediatrics.  He is a member of the American Medical Association, the Medical Society of Virginia, and the Tricounty Medical Society. 

Dr. Sweeney is an avid supporter of the Children’s Hospital of the Kings Daughters and has been a Gold sponsor of the annual Midnight and Mistletoe fund-raising gala since its inception.  

He is honored to have been named by his peers as a Coastal Virginia region “Top Doc” in Allergy and Immunology on numerous occasions.  To book an appointment with Dr. Sweeney call us or fill the online appointment request.
