BRANDON BUNTEN
CHAIRPERSON
“Defenders of Freedom became family when I needed support. Now I’m honored to help other veterans find that same sense of belonging.”
Brandon Bunten serves as Chairperson of Defenders of Freedom Oklahoma. A Purple Heart recipient and U.S. Army combat veteran, Brandon served with Easy Company, 2nd Battalion, 506th Infantry Regiment, 4th Brigade Combat Team, 101st Airborne Division (Air Assault), deploying to Iraq in 2005–2006 and Afghanistan in 2008–2009.
Following his military service, Brandon worked in the oil and natural gas industry and later served as a security contractor with Triple Canopy at the U.S. Embassy and BDSC in Iraq. After returning home, he joined ONEOK.
Brandon became part of the Defenders of Freedom family in 2011, when Donna connected with him during his journey with traumatic brain injury (TBI) and post-traumatic stress (PTS). Her support for Brandon and his family led to his first Defenders of Freedom golf outing in Dallas. The relationships he formed grew into a lasting commitment to the organization. As Chairperson, Brandon brings personal experience, compassion, and a deep dedication to helping fellow veterans and their families find healing, support, and community.
