Our Story

Our practice was started by George S. Tate, DDS in 1966 and later joined by his son, Richard H. Tate, DDS in 1983. Their reputation for compassionate and exemplary care was legendary throughout the Roanoke and New River Valleys. Dr. Richard Tate retired in 2018 at which time Christopher S. Hansen, MS, DMD inherited their legacy.

Christopher Hansen


Dr. Hansen was born in Seattle, completed his dental school at Nova Southeastern University in South Florida and an orthodontic residency at Louisiana State University, and is pleased make a home with his wife, Christina, and daughter, Naomi, here where many of his family's roots spring. 

He is a board certified orthodontist--a distinction achieved by only about 1 in 3 orthodontists--and keeps up to date with the latest advances and research in the field, but mostly he just enjoys making his patients smile. 

Outside of the office, he enjoys the outdoors, golfing, a good book on the beach, and tries to stay active in his church and community. More than anything, however, he simply likes to spend time with his wife, daughter, and their dog Toby.
