As a Pennsylvania native, Dr. David Gregory, D.O. is excited to serve the Lancaster and Lebanon community. He finished his orthopedic surgery residency at Michigan State University and McLaren Macomb Hospital in Mount Clemens. Following that, he completed an outpatient hip and knee replacement fellowship at Nano Clinic in Arroyo Grande, California, and then a second fellowship in adult reconstruction at Cedars-Sinai Medical Center in Los Angeles, California.
