Combat PTSD Board of Directors

David F. Tharp, PsyD. started because all of us have an intense passion for serving veterans.  PTSD and suicide are two of the most challenging issues facing our military and veterans today.  Because of the cost on military members and their families, I decided it was time.  Time to find a new approach.  Dr. Tharp serves as the PTSD Program Manager in Waco, Texas and is a Lt Col in the Air Force Reserves at the United States Air Force Academy. He experienced first-hand the cost of war on our military men and women after serving as a NATO Medical Advisor in Kandahar, Afghanistan. It was his responsibility to notify the country or service of those KIA and that of civilians as well, among many other responsibilities.  He and his wife, Katherine Tharp, MD have two active boys and live in China Spring, Texas.

Col. Peter Coldwell, MD

COL Coldwell has served in the US military for 38 years, beginning his career in 1980 on active duty as a Private Airborne medic; he is currently assigned as the State Surgeon (senior medical officer) for the Texas Army National Guard/Texas Military Forces. Of his 38 years 8 have been on active duty, to include combat tours to Iraq and Afghanistan. As a senior military physician, he, all too often, sees the ravages of the “silent killer” of combat, PTSD. Wars and conflict have always taken a heavy toll on the psychiatric and emotional wellbeing of the combatants; however, the Global War on Terror is unique in is length and breadth, the first Gulf War being August 1990. The suicide rate has been alarming and often attributable to service and PTSD; COL Coldwell has seen more soldiers die by their own hand than by the direct action of the enemy. It is the suffering of his fellow service members and Veterans that prompted COL Coldwell to join with Combat-PTSD with the goal of decreasing the rates of PTSD and suicide.

As a civilian Dr. Coldwell practices Emergency Medicine in San Antonio and Alpine, TX. In addition, he works as an expert witness utilizing his skills as a board-certified family medicine doctor, military physician and flight surgeon. He volunteers as the EMS medical director for one of the local counties’ EMS service.  He has two children currently in college. He is an avid motorcyclist and member of the Combat Veteran’s Motorcycle Organization (a Veteran’s support organization).
