Dr. John Kintiroglou is committed to providing the highest level of care to infants, children and adolescents. Founded by his father Dr. Constantinos Kintiroglou in 1981, Kintiroglou Pediatrics has been caring for patients for more than 30 years and recognizes the importance of treating the whole child. Dr. John joined the West Orange office in 2000, and the practice has since expanded to three locations with a fourth slated for Chatham. “Our practice is at its core a family practice, so I’m truly passionate about what I do,” says the father of three daughters. 

Kintiroglou Pediatrics individualizes care for each patient, and the doctors always maintain two-way communication with parents. The staff strives to establish close relationships with patients as well as their families. 

“The children I took care of when they were adolescents are now bringing their babies back into our practice,” Dr. John says. “We form relationships with our patients not only to maintain their health but also to help them grow into the best people they can be.”
