Ben Richards

Ben Richards, Director
Ben Richards is a former Army officer and Traumatic Brain Injury (TBI) survivor who has personally benefited from Hyperbaric Oxygen Therapy. While commanding an Armored Cavalry Troop in Iraq in 2007, Ben survived an attack by a suicide bomber driving a sedan laden with hundreds of pounds of explosives that destroyed his 22-ton armored vehicle. A few weeks later he suffered a second TBI from the blast of a road-side Improvised Explosive Device (IED). He was subsequently medically retired from the Army as a result of his “invisible wounds.”

After five years of traditional “standard model of care” treatment for TBI and Posttraumatic Stress Disorder (PTSD) that did little to improve his condition or functionality, Ben received Hyperbaric Oxygen Therapy (100% oxygen at 1.5 atmospheres of pressure) pro bono from one of the many HBOT clinics committed to helping veterans. The treatment substantially improved his condition to the extent that he can now join the hundreds of other TBI survivors treated with HBOT in saying that he “has gotten his life back.”

Ben is a graduate of the United States Military Academy at West Point and has a Master of Arts degree from Georgetown University. In addition to the National Hyperbaric Association, he works with several other non-profit organizations dedicated to improving treatment for military service members and veterans with TBI and PTSD.

Dr. Sherr is a member of the Undersea and Hyperbaric Medical Society as well as the Society of Hospitalist Medicine. He is one of the few medical doctors in the country using an integrative approach to hyperbaric treatment (with targeted lab work, diet, supplementation, and both mental and physical exercise) to further advance HBOT’s ability to heal wounds and optimize physiology.

Dr. Sherr also has a special interest in the use of HBOT for traumatic brain injury, stroke, and optimal performance (physical and cognitive).


Captain Matthew Smothermon

Captain Matthew Smothermon, Director
Prior to his deployment to Afghanistan, Captain Matthew Smothermon earned a degree in mechanical engineering from the University of Tulsa, and completed two years of law school.

In 2011 as a platoon leader his mission was to seek out and eliminate the threat of improvised explosive devices. While deployed, Captain Smothermon’s vehicle was struck by three very large IEDs, all in the span of about a month. Miraculously he walked away from each event, although he was hospitalized and ultimately taken off the front lines as a result of his injuries.

While he suffered a variety of physical injuries, perhaps the most debilitating side-effect of the blasts was his traumatic brain injury. In the immediate aftermath, Captain Smothermon could barely concentrate enough to read a piece of paper, and he could hardly sleep through the night.

And while there was a natural recovery period for his TBI, as his brain adapted to its newfound roadblocks and failures, the recovery process eventually plateaued. Upon returning home, his brain injury began to take root, and it affected everything he did to the point that it changed who he was.

In 2012, Captain Smothermon learned of a medical research study being conducted by Oklahoma State University. Within two weeks of beginning daily one-hour sessions, he found himself sleeping through the night.

Within twenty sessions, the static gears of his mental machinery began spinning back to life. By the time he had undergone 40 sessions, what had once been a dense mental fog had given way to clarity for the first time in well over a year.

Not only could he think clearly again, but he returned to law school. By the time Captain Smothermon had completed the full 80 sessions of hyperbaric treatment, not only had he returned to full capacity as a soldier and leader, but he had taken over as the company commander of his deploying unit.

Today, Captain Smothermon can safely say that he has recovered from his traumatic brain injury. A full year after he returned from war, his wife looked at him with tears in her eyes and said, “It’s good to have you back.”
