Ketamine Therapy for PTSD in Scottsdale

PTSD is not simply a memory problem. It is a disorder of how the nervous system encodes, stores, and retrieves threatening experiences. In PTSD, the amygdala — the brain's threat-detection center — becomes hyperactive, while the prefrontal cortex, which provides context and regulation, becomes underactive. The result is a nervous system perpetually primed for threat, unable to distinguish past from present danger.

First-line treatments, including SSRIs and trauma-focused therapies such as EMDR and prolonged exposure, are effective for many patients. But a substantial portion of people with chronic PTSD do not achieve remission through these approaches alone. The trauma remains neurologically encoded, and the dysregulated threat-response persists.

Ketamine works through a fundamentally different pathway. As an NMDA receptor antagonist, it interrupts the process of memory reconsolidation — the mechanism by which traumatic memories are re-encoded each time they are recalled. This creates a therapeutic window in which the emotional weight of traumatic memories can be reduced and new, more adaptive neural pathways can form.

Dr. Andrew Zabel is an Army veteran and board-certified Emergency Medicine physician. He founded Innerbloom with a specific understanding of how military service, combat trauma, and operational stress shape the kind of PTSD that does not always respond to conventional treatment.

The veteran mental health crisis is real and ongoing. By some estimates, approximately 22 veterans die by suicide every day in the United States. Existing treatment infrastructure is overwhelmed, waitlists are long, and many veterans distrust traditional mental health systems. Innerbloom was built to be a different kind of option — physician-led, private, and staffed by someone who has served.

Innerbloom is in the process of applying to the VA Community Care Network to expand access for veterans. In the meantime, we offer priority intake scheduling for veterans and first responders. First responders, law enforcement officers, and emergency medicine professionals also carry elevated rates of occupational trauma and PTSD — Dr. Zabel's EM background gives him particular fluency with this population.

PTSD treatment at Innerbloom begins with a free physician intake with Dr. Zabel — a thorough evaluation covering your trauma history, current symptom burden, psychiatric and medical history, and medications. It is also an opportunity to ask questions and determine whether ketamine is the right fit.

If appropriate, the standard protocol is an induction series of four to six IV ketamine infusions over two to three weeks. Each session is physician-supervised throughout. Many patients with PTSD find that ketamine reduces the intrusive quality of traumatic memories, lowers baseline hyperarousal, and creates a window of psychological flexibility that supports ongoing therapy. Integration support follows to help consolidate those shifts.

For patients with co-occurring treatment-resistant depression and PTSD, we also offer Spravato (esketamine), the only FDA-approved ketamine product for treatment-resistant depression. Innerbloom is REMS-certified. See our pricing page for current rates.
