He attended Wagner College in Staten Island, NY where he graduated from a 5 year, accelerated BS/MS Physician Assistant program. While in PA school, Zachary was a patient at HSS where he had his first taste of orthopedic surgery. This experience gave him a strong desire to pursue a career in orthopedics. Zachary’s medical mission trips to Guatemala and Peru, where he provided care to those in remote, underdeveloped villages, convinced him that deformity correction was his ideal field of practice.
