Gregory L. Kirk, M.D.​

Aviation Psychiatry and Dr. Kirk

Companies since 2013
Pilots Evals in 2022

I keep a nationwide practice and my pilots fly for every legacy carrier. I also work with general aviation pilots, student pilots, and Air Traffic Control applicants. Away from aviation, I am a referral clinician for the NBA, a treating clinician in the NFL Program for Substances of Abuse, a 5280 Magazine “Top Doc” in Addiction Psychiatry, and an expert in suicide and unintentional death from substance abuse, mental illness, and behavioral disorders.

I started seeing pilots at Rocky Mountain Psychiatry Consultants in 2012 and founded the specialty aviation clinic, Aviation Psychiatry, LLC, in 2017. Aviation Psychiatry expanded to Las Vegas in 2020. Referrals come from everywhere, such as Part 121 HIMS managers, corporate medical departments and pilot advocates, the nation’s leading HIMS AMEs and Neuropsychologists, all United States pilot unions, flight schools, attorneys, and the web.
