Born in Abilene, Texas, Bishop Smith grew up in Tuscola, a small town in the nearby farm and ranch country. He studied at Baylor University (BA and MA), Nashotah House (MDiv), and Sewanee (DMin) and was ordained deacon and priest in the Diocese of Northwest Texas. Beginning his parish ministry there, he also served in Western Michigan and Iowa. After thirteen years as rector of St. Andrew’s, Des Moines, Smith was elected Bishop Coadjutor of the Diocese of Missouri in 2001 and ordained bishop in 2002. Later that year he was seated as the Tenth Bishop of the Diocese, where he served until 2020.

He and his spouse Debra Morris Smith, married for forty-four years, live in St. Louis. They have three adult children, all married, and three grandchildren. Smith has served the wider Church on various boards and commissions and has chaired legislative committees for the General Convention. For rest and recreation Smith likes to read, walk, bake bread, collect vintage fountain pens, and FaceTime with children and grandchildren. The Smith household includes an aging cat, Dora, and a Kerry Blue Terrier, Molly.
