The department of pediatrics consists of more than 70 board certified pediatricians and subspecialists, in addition to more than 30 medical faculty members with joint appointments in other disciplines including surgery, anesthesia, dentistry, psychology, pathology, and radiology. The hospital-based practice is further complemented by an extensive network of community pediatricians who practice within the Geisinger network throughout the surrounding counties.

Subspecialty sections add to the diversity of the extensive general pediatric practice. These subspecialty sections include adolescent medicine, allergy, cardiology, infectious disease, endocrinology, nephrology, hematology/oncology, immunology, gastroenterology and nutrition, critical care, neonatology, neurology, dermatology, neurodevelopmental pediatrics, rheumatology, pediatric emergency medicine and pulmonology.

Like our faculty, our pediatric residents choose to come to Geisinger because of the unique experience that it offers - a chance to practice academic primary and tertiary care pediatrics in a rural setting. Many of our residents enter into the field of primary care, some stay in the area, while other graduates enter into subspecialty training to pursue careers in academic medicine. These graduates have been accepted to fellowships through the country in institutions such as Boston Children's Hospital, Baylor College of Medicine, Duke University, Massachusetts General Hospital, Medical College of Virginia, Rainbow Babies and many others.

Medical students from Temple University and Philadelphia College of Osteopathic Medicine rotate through our hospital and clinics as part of their core pediatric rotation. In addition, numerous students from other institutions also choose to do electives here.
