✓ Last verified: January 22, 2026 — Edited & verified by Angelica Bottaro for HealingMaps Editorial Staff

Known For: Board-certified psychiatrist-led clinic offering both IV ketamine and Spravato for depression, with thorough pre-treatment screening. Dr. Martha St. John is a Fellow of the American Psychiatric Association and member of the American Society of Ketamine Physicians.

HealingMaps Take: St. John Mental Health Clinic brings strong psychiatric credentials to ketamine therapy in Houston. Dr. Martha St. John’s dual membership in the American Psychiatric Association (as an elected Fellow) and the American Society of Ketamine Physicians ensures patients receive treatment from someone deeply experienced in both psychiatry and ketamine medicine. The clinic’s thorough pre-treatment screening — including full physical and mental health evaluations — reflects a safety-first approach. Offering both IV ketamine and Spravato gives patients flexibility, and the clinic’s insurance acceptance for psychiatric services means the overall care plan can be more affordable even if ketamine itself is out-of-pocket.

Market Position: St. John Mental Health is a Spravato-certified clinic in the Houston metro. Spravato (esketamine) is the FDA-approved ketamine treatment that most commercial insurance plans cover after prior authorization — unlike cash-pay IV ketamine.

Patient Questions about St. John Mental Health

This 4-question summary is matched to the protocols and conditions St. John Mental Health treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.

What ketamine protocols does St. John Mental Health offer?

St. John Mental Health offers Spravato and IV ketamine — a 2-protocol practice. Patients can switch between or combine modalities without changing providers. Confirm specific dosing schedules and which protocols are recommended for your condition during your consult.

Does St. John Mental Health offer Spravato (esketamine)?

Yes — St. John Mental Health offers Spravato, which means they’re FDA REMS-certified and maintain the required two-hour in-office monitoring window after each dose. Spravato is the primary insurance-covered ketamine option for treatment-resistant depression. Worth confirming the prior-authorization timeline before booking your first session.

Is St. John Mental Health suited for treatment-resistant depression?

St. John Mental Health treats depression via Spravato (FDA-approved for TRD), and IV ketamine (off-label, evidence-based). The Spravato pathway is the most likely to obtain commercial insurance coverage. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.

Can St. John Mental Health help with anxiety disorders?

Yes — St. John Mental Health treats anxiety, including generalized anxiety, social anxiety, and panic disorder. The evidence base for ketamine in anxiety is less robust than for depression, but it can be a meaningful option for patients who haven’t responded to SSRIs or benzodiazepines. Worth asking which of their protocols they typically recommend for anxiety-primary patients.
