Sam Peterson’s story begins in the heart of conflict zones. Serving as a bomb technician in the U.S. Army, Sam disarmed explosives in Afghanistan. “I was the guy in the big green suit cutting wires on IEDs,” he recalls. But when the combat ended, another war began. This time, within his own mind. Returning home, Sam faces relentless panic attacks, emotional numbness, and a darkness that nearly costs him his life.
Traditional methods fail him. “I’d been on SSRIs, beta-blockers, and tried talk therapy. Nothing worked,” Sam shares. One night, at his lowest point, a phone call from a friend interrupts his suicide attempt. That call becomes a turning point. What follows is a journey of self-discovery and scientific exploration. It transforms not only his life but the lives of countless veterans battling PTSD.
Now, as co-founder of Mind Spa Denver, Sam is pioneering a multidimensional approach to trauma recovery. He is combining different therapies to treat PTSD, anxiety, and depression. These include psychedelic therapy, ketamine infusions, hyperbaric oxygen therapy, and transcranial magnetic stimulation. His mission is clear: to bring these life-saving tools to veterans and first responders who have run out of options.
For many veterans, PTSD is more than psychological; it’s biological. Chronic stress, brain inflammation, and traumatic brain injuries (TBI) can rewire neural pathways. They can trap the brain in survival mode. “PTSD is a wiring problem,” Sam explains. “Neurons that fire together, wire together. We have to break that pattern to heal.”
This understanding drives Mind Spa Denver’s integrative model. It focuses on reducing inflammation, improving oxygenation, and restoring neuroplasticity. It is the brain’s ability to form new neural connections. “Everything we do in mental health is about rewiring the brain,” Sam says. “When we downregulate inflammation and increase neuroplasticity, the brain finally has a chance to heal.”
One of the most effective tools in Peterson’s approach is ketamine therapy, which offers rapid relief for depression, anxiety, and PTSD. The WHO classifies Ketamine as one of the most important medical discoveries. It is showing remarkable results in cases where traditional antidepressants have failed.
“Ketamine is like hitting control-alt-delete for your brain,” Sam explains. “It downregulates inflammation, increases neuroplasticity, and gives the nervous system a chance to reset.” Patients often describe the experience as dissociative yet profoundly healing. The therapy provides a window of clarity. This allows other treatments like talk therapy and mindfulness to work more effectively.
Sam’s first encounter with MDMA is deeply personal. “It was the most transformative experience of my life,” he recalls. “It felt like someone took my soul out, washed it, and put it back in.” For veterans trapped in cycles of fear and self-blame, MDMA-assisted psychotherapy is proving to be a breakthrough in trauma recovery.
“Psychedelics can increase neuroplasticity and give you a chance to change,” Sam notes. The substance helps patients process trauma without triggering the fight-or-flight response. “It creates a sense of biological safety,” he adds. “Once you’re resourced, you can face your trauma without being overwhelmed.”
This emotional safety is vital for building emotional resilience. Especially for men conditioned to suppress vulnerability. As Marc observes during the discussion, “Men often carry trauma silently, masking it with anger or withdrawal.” Through psychedelic therapy, many are learning to reconnect with themselves and others in ways they never thought possible.
Another cutting-edge tool in Peterson’s arsenal is hyperbaric oxygen therapy (HBOT). Inside a pressurized chamber, patients breathe concentrated oxygen, saturating the bloodstream and delivering oxygen directly to brain cells. “It’s like bathing your brain in oxygen,” Sam says. “It helps the brain create clean energy and supports cellular repair.”
HBOT is particularly effective for veterans with TBI and chronic PTSD. Studies from Israel show a 75% success rate in reducing PTSD symptoms after 40–60 sessions. Combined with transcranial magnetic stimulation (TMS), a treatment that strengthens underactive brain regions, HBOT forms part of a holistic strategy to rebuild brain function and restore mental clarity.
Peterson’s work is not just about science. It is about saving lives. “We’re losing too many veterans to suicide,” he says. “If you’re a veteran, you’re one and a half times more likely to take your own life. If you’ve had a TBI, that number triples.”
At Mind Spa Denver, the mission of suicide prevention is personal. By combining biological, psychological, and emotional interventions, Sam and his team are rewriting what’s possible for those suffering in silence. “We have the tools to change how the mind processes trauma,” he insists. “No one should have to stay stuck in pain.”
Sam Peterson’s journey from combat to clinical innovation illustrates a powerful truth. Healing PTSD requires more than medication and talk. It demands a whole-brain approach. Through psychedelic therapy, ketamine infusions, and hyperbaric oxygen therapy, veterans are rediscovering hope, purpose, and emotional resilience. As Marc concludes, “This isn’t alternative medicine. It’s effective medicine.”
Sam Peterson is the co-founder of Mind Spa Denver, a psychiatric and functional medicine clinic specializing in trauma recovery for veterans and first responders. A former U.S. Army bomb technician, Sam transforms his lived experience with PTSD into a mission to innovate mental health treatment.
Combining advanced neuroscience with compassionate care, Sam’s integrative model incorporates ketamine therapy, psychedelic-assisted psychotherapy, transcranial magnetic stimulation, and hyperbaric oxygen therapy. This helps clients heal both brain and body. His work continues to redefine how the medical community approaches trauma, resilience, and recovery.
