Mount Nittany Physician Group

Specialties and Biography

Dr. Wesner says that he chose pediatrics because he enjoys being around children and finds it rewarding not only to care for his patients, but also to comfort them and make seeing the doctor as fun as possible.

“As a severely asthmatic child, I learned how impactful and positive it can be to visit a doctor who is fun and goofy, and I hope that my bedside interactions with these kids can help them make the most out of an otherwise scary experience,” he shares.

Dr. Wesner earned his bachelor’s degree in pre-med and psychology from The Pennsylvania State University, and his medical degree from Lake Erie College of Osteopathic Medicine, Erie Pennsylvania. He completed his pediatric residency at Geisinger Medical Center in Danville, Pennsylvania, where he served as a pediatric and neonatal hospitalist, and later as the hospital’s pediatric chief resident. Before joining Mount Nittany Health, Dr. Wesner was most recently employed as a pediatric hospitalist at St. Luke’s University Health Network in Bethlehem, Pennsylvania.

Dr. Wesner is board certified by the American Board of Pediatrics in General Pediatrics and Pediatric Hospitalist Medicine. He is a member of the American College of Osteopathic Pediatricians and the American Academy of Pediatrics.

On joining the pediatric hospitalist program, he says, “I was very impressed and intrigued by Mount Nittany Health’s commitment to want to invest in their inpatient pediatric services in order to keep more sick infants and children closer to home for their hospitalized care.”

Outside of the office, Dr. Wesner enjoys spending time with his wife, Stephanie, and their 14-month-old daughter, Brielle. His hobbies include bird watching, archery, maple syrup production and anything related to Penn State Athletics.
