COLORADO SPRINGS, Colo. — Ketamine infusions are an up-and-coming treatment some say is helping with PTSD and depression for our local veterans.

Theresa Keefer is a certified registered nurse anesthetist and the owner of Military Matters Ketamine Infusion Therapy Clinic in western Colorado Springs. She said ketamine was first used in the 1960s, and it just made its way to southern Colorado.

Keefer’s clinic focuses on helping veterans struggling with severe PTSD and depression. In the video above, FOX21’s Courtney Fromm catches up with one veteran who says it changed his life.
