Our Practice


Providence Pediatric Practice was established by Dr. Jacquelyn Gibbons in her home in Upper Providence -- she was joined by Dr. Olivia DiMaggio in 1980 and the practice remained there until 1999 when the office moved to it's present location behind Toys'r'us.

We happily continue to provide care to generations of families that were part of Dr. Gibbons early practice and the wonderful new families who have joined us.

Our mission is to provide quality care for children and their families as we guide them through normal development, monitor growth, treat illness and help address behavioral concerns along the way.  We remain an independent private practice with a wonderful support staff of nurses and administrative personnel.
