Desmond Wallington, PhD, is a licensed psychologist who provides Ketamine-Assisted Psychotherapy in Denver, CO. Dr. Wallington earned his PhD in Counseling Psychology and MS in Community Counseling from Oklahoma State University in Stillwater, OK. Prior to becoming a licensed psychologist, Dr. Wallington worked as a Licensed Professional Counselor. While at OSU, Dr. Wallington conducted research in forgiveness and American Indian Enculturation. Dr. Wallington’s passion for working with entheogenic and psychedelic medicine stems from his American Indian heritage, which fuels his passion for integrating his ethnic heritage with his professional training. Prior to working with psychedelic medicine, the majority of Dr. Wallington’s work centered on Post-Traumatic Stress Disorder (PTSD). Dr. Wallington has found expanding his practice to include psychedelic work has resulted in more dramatic and drastic results than his previous modalities like talk therapy and Eye Movement Desensitization and Reprocessing.

Making Changes

Dr. Wallington found his way to working with Ketamine after working on the historic Initiative 301 campaign in Denver that decriminalized psilocybin mushrooms. His political activism in the Denver campaign opened the door for him to gather petition signatures for the 2020 Decriminalize Nature DC campaign to decriminalize entheogenic medicine in Washington DC for their November 2021 campaign.
