Healing Arizona Veterans Volunteer Board and Senior Staff
Board Members
Robert Sexton, M.D.
Dr. Sexton has been a resident of Tucson since 1989 where he was in private practice until 2008. At that point, he rejoined the military after an almost 38 year break. Once again a U.S. Soldier, he was deployed to Iraq and Afghanistan where he was a physician with Civil Affairs and a Field Surgeon attached to a forward deployed unit. In 2009, during his Iraq deployment, he was diagnosed with Guillain-Barre Syndrome and was treated with plasmapheresis for the acute phase of the disease. Four years later, he once again began experiencing severe symptoms similar to his prior GBS experience. After neurological evaluation, he was then treated with HBOT, which resulted in a very significant clinical improvement — “a life changer.” Dr. Sexton’s military, medical and personal experience with this therapy gives him a unique perspective as a strong advocate for HBOT.
