He subsequently received his medical degree from Albert Einstein College of Medicine where he was inducted into the Alpha Omega Alpha honor society. Dr. Shepard completed his orthopedic surgery residency at New York University (NYU) Langone Orthopedic Hospital, formerly NYU Hospital for Joint Diseases. He completed a spine surgery fellowship at the internationally renowned Midwest Orthopedics at Rush University Medical Center, where he underwent extensive training in minimally invasive spine surgery and cutting-edge techniques including the use of robotics, computer navigation, and 3D augmented reality in spine surgery.

Dr. Shepard remains active in the academic community having authored over 35 peer reviewed publications, presentations and abstracts, as well as multiple book chapters. His work has been presented at both national and international meetings and he currently holds membership with AO Spine, the North American Spine Society (NASS), American Academy of Orthopedic Surgeons (AAOS), and International Society for the Advancement of Spine Surgery (ISASS).
