Meet Dr. Brian Christiansen

I’m Dr. Christiansen. I have been in practice in East Tennessee since 2007 and feel like I’m home. I grew up in Texas. Joined the Army Reserves out of high school. Spent 2 years as a missionary in Argentina. Got a bachelor’s degree from BYU and spent 2 years at UT Austin for the prerequisites for podiatry school. I went to Miami for podiatry school and did a 3-year surgical residency in Upstate New York. I found my wife in Utah and together we are raising our 2 boys and 2 girls. I love my job and look forward to going to work every day because I know I get to do something to help my patients and that is awesome!
