Jonathan D. Evans, DDS

Dr. Evans moved to Sierra Vista when he was 12 years old.  He attended Buena High School, graduating in 1999. Dr. Evans served a two year mission for his church in Seattle after high school. He then attended Eastern Arizona College where he met his wife.  They were married in 2004 and now have five children.  After EAC, he transferred to Western New Mexico University and graduated with a Bachelor’s of Science degree.  Following graduation he and his family made the long trek to Indianapolis where Dr. Evans attended Indiana University School of Dentistry.  He graduated with his D.D.S. in 2012 and has worked at Sierra Vista Dental since that time.

Dr. Evans enjoys spending time with his wife and kids. When he isn’t with them or at the office, you’ll find him in the garage working on cars. Classic cars have always been his passion and he started restoring them during high school.  His high school car was a 1964 Chevy II with a 327 cubic inch engine. When he and his wife first got married they had a 1957 Chevy Bel Air with a 327 and a 3 speed manual transmission. That car was later sold to buy a more family friendly, yet not as exciting, vehicle. His current project is a 1964 Chevy Corvair.
