After earning his medical degree and interning at the University of Texas Health Science Center at Houston, Dr. Atkinson completed a psychiatry residency at UT Southwestern and a child and adolescent psychiatry residency at the University of Alabama at Birmingham. In 2010, he completed addiction treatment training through a Mayo Clinic Fellowship.

Dr. Atkinson’s interest in addiction treatment developed after seeing firsthand the effects of substance abuse during his residency training. Dr. Atkinson treats substance abuse disorder and addiction with the understanding that it’s a pediatric disease, usually developing during adolescence. Dr. Atkinson’s research interests include adolescent substance use as well as aggression in children.

Dr. Atkinson is an active member of the American Academy of Child Adolescent Psychiatry, the American Academy of Addiction Psychiatry and the Texas Society of Child and Adolescent Psychiatry. He serves on the board of directors for the Low Birth Weight Development Center, an organization that provides parent training, therapy and follow-up care for children who were born premature.
