Before opening Crossway Medical Clinic, Dr. Schrader practiced at Saints Physicians North and Mercy Northwest Family Clinic in Oklahoma City. He has treated patients across the globe in emergency rescue/disaster operations and on medical mission trips.

Dr. Schrader and his wife have five children. He enjoys staying active with his family through cycling and coaching youth sports teams.
