Top Dentist in Pike Creek | Dr. Jason Justison

Dr. Jason Justison

Dr. Justison grew up in Pike Creek, Delaware, just around the corner from the office. He received his undergraduate degree in Biology, minor in chemistry from University of Delaware, researching cancer biology, physics, and biochemistry. He then went on to dental school at Temple University in Philadelphia, PA and attended a hospital-based general practice residency at Lancaster General Hospital in Lancaster, PA. He has been practicing in Pike Creek, Delaware ever since, coming full circle. 

Dr. Justison strives to be the most gentle and pain-free dentist. His favorite part of dentistry is handing the patient the mirror and seeing their face light up after fixing a fractured front tooth right on the spot. He enjoys relieving a patient in pain and truly cares to help patients figure out the best possible treatment plan that fits with their comfort level and budget. He doesn't mind coming into the office on a Saturday or Sunday to help you out. He likes to keep his patients laughing and to have as good a time as possible considering they are in a dental chair!

Jay lives with his wife and infant son right near the office. He enjoys going for hikes with his family, road and mountain biking, snowboarding, and running in local 5K's. He recently won the Bolton Landing Turkey Trot on scenic Lake George in upstate New York while visiting extended family. Jay's typical habitat is on the floor playing with toys or reading books with his infant son Nolan, on the treadmill at the gym with his wife Liz, or in front of the TV with family and friends watching the Super Bowl champion Eagles play!
