R. David Hammer, Ph.D.

Early Career

David Hammer, a Marine Corps combat veteran of Vietnam, flew 100 combat missions as an A-4 jet pilot. He is Professor Emeritus of Civil and Environmental Engineering at the University of Missouri. After receiving his B.S. in Engineering from the United States Naval Academy, he went on to earn an M.S. in Forest Ecology and a Ph.D. in Soil Science. In addition to his 23 years with MU, he has mapped forest soils in the Cascade Mountains of Northwest Washington for the Washington State Department of Natural Resources and worked for the U.S. Forest Service. With the Soil Conservation Service, David served as both the National Leader for Soil Survey Investigations and the Director of the National Soil Survey Laboratory. He served in the Environmental Protection Agency as the Chief of the Terrestrial Ecology Branch.


David is co-founder of the not-for-profit organization All the Way Home This special organization has the dual objectives of raising public awareness concerning moral injury and post traumatic stress among American military veterans, as well as providing safe, non-judgmental settings within which veterans can begin to transform back into civilian life by telling their stories. He is well known among veteran’s organizations throughout Central Missouri and has served in veteran advocacy roles in both the public and private sectors.

Healing Journey

In 2008, David encountered late onset PTSD resulting from his previous military experiences. Since that time, as he works to find balance from his “soul wound”, he has been active in learning about this affliction, finding effective processes for it and working with others trying to help veterans. He has been an integral component in the development of Guardian Hills.
