In this episode of Made for Health, Dr. Aaron Hartman sits down with Dr. James T. Leathem, DO, a board-certified anesthesiologist and psychedelic integration coach, to explore ketamine therapy, psychedelic medicine, and a different way of thinking about mental health. Dr. Leathem shares his unconventional path from business to medicine, how a near-death experience helped redirect his life, and how his background in anesthesia eventually led him into ketamine-assisted care. The conversation focuses on depression, PTSD, trauma, chronic pain, neuroplasticity, and the importance of pairing the medicine with meaningful integration work.
Dr. Leathem explains that ketamine is a dissociative anesthetic used at sub-anesthetic doses in this setting. He describes how ketamine interacts with the glutamate system through NMDA receptor blockade, which can influence AMPA signaling and brain-derived neurotrophic factor, or BDNF. He connects these mechanisms to synaptic plasticity, dendritic spine formation, and a period of increased neuroplasticity that may create an opportunity for new patterns and behaviors.
But for Dr. Leathem, the medicine itself is only part of the process. He emphasizes preparation, intention, integration coaching, mindfulness, journaling, sleep, and daily practices after treatment. His analogy is simple: ketamine may help put out the fire in your "mental health house," but it cannot rebuild the house for you. That rebuilding requires active participation after someone becomes unstuck.
The conversation also expands into the default mode network, spiritual experiences, stellate ganglion blocks, autonomic dysregulation, traumatic brain injury, and the wider landscape of psychedelic medicine. Throughout the episode, Dr. Leathem emphasizes individualized treatment rather than a cookie-cutter approach.

In This Episode, You Will Learn
✅ How Dr. Leathem went from anesthesiology to ketamine and psychedelic medicine
✅ How ketamine works differently from conventional approaches focused primarily on serotonin and other monoamine neurotransmitters
✅ Why NMDA receptors, glutamate, BDNF, and neuroplasticity are central to the conversation about ketamine
✅ Why Dr. Leathem believes the period after a ketamine experience can be as important as the infusion itself
✅ How preparation, intention, integration coaching, and daily practices can help patients work with the changes that follow treatment
✅ Why ketamine may help someone become "unstuck," while long-term rebuilding still requires active participation
✅ How the default mode network may relate to ego, thought patterns, and psychedelic experiences
✅ How ketamine and stellate ganglion blocks are being combined in Dr. Leathem's practice when addressing certain patterns of autonomic dysregulation

About Dr. James T. Leathem, DO
Dr. James T. Leathem is a board-certified anesthesiologist, Certified Psychedelic Integration Coach, and co-founder of Gilbert Chandler Ketamine Therapy Clinic and Scottsdale Ketamine Therapy Clinic. His background in anesthesia provided the foundation for his work with ketamine and altered states of consciousness.
After beginning his career in business and marketing, a series of deeply personal experiences led him toward medicine. He went on to earn his Doctor of Osteopathic Medicine and build a career in anesthesiology before transitioning into ketamine and psychedelic medicine. In the episode, he explains that his clinics have performed thousands of ketamine infusions and that his approach combines the medicine with preparation and integration rather than treating the infusion as a standalone intervention.
His work focuses on helping individuals struggling with conditions including depression, PTSD, trauma, chronic pain, and other mental health challenges, while emphasizing personalized care and the potential for lasting behavioral and personal change.
