Laser Therapy Institute Podcast

This episode reviews a 2026 pilot study evaluating the effects of photobiomodulation therapy (PBMT) on inflammatory and cartilage biomarkers in patients with advanced knee osteoarthritis. We discuss the biologic rationale for PBMT, changes in serum and synovial fluid cytokines, and whether these findings move PBMT closer to being considered a disease-modifying intervention rather than simply a symptomatic treatment.

Joining us today is Tommy Mulhern — Physician Associate, Marine Corps Veteran, and emerging voice in the field of psychedelic-assisted therapy. Tommy and Dr. Rountree served together in the Marines and recently reconnected over their shared interest in advancing healthcare. After years working in conventional medical roles, Tommy became increasingly aware of healthcare's shortcomings in addressing mental and emotional suffering. Guided by his own healing journey and work with ketamine and psilocybin-assisted therapy, he now devotes himself to bridging conventional medicine and natural medicines — helping individuals access deeper, more complete healing while contributing to the growing movement advancing safe and accessible psychedelic care.

As discussed in the podcast, screening and post-experience integration are essential for successful treatment. Tommy provides information and clinical screening for patients seeking psychedelic-assisted therapy to improve outcomes for patients with PTSD, depression, and addiction.
