HealingMaps Take: McLean Hospital is one of the world’s leading psychiatric hospitals — a Harvard Medical School affiliate that pairs the ketamine service with the broader ECT/TMS interventional psychiatry stack and full inpatient psychiatric care. For Boston-area patients with severe treatment-resistant depression who want academic-medical-center clinical depth (rather than a standalone infusion clinic), McLean is the natural choice. The Belmont main campus location is accessible from Cambridge, Watertown, Waltham, and the western Boston suburbs.
Market Position: McLean Hospital Ketamine Service is the Harvard Medical School-affiliated academic-medical-center option for Boston-area ketamine — distinct from the independent infusion clinics that dominate the rest of the Boston market. Treatment fits within McLean’s broader psychiatric continuum (outpatient + inpatient + ECT + TMS).
Is McLean Hospital Right for You?
✓ Choose McLean Hospital if:
- You have severe treatment-resistant depression or bipolar depression and want academic-medical-center clinical depth
- You want ketamine integrated with broader interventional psychiatry (ECT, TMS) and the option of inpatient care if symptoms escalate
- You’re located in Belmont, Cambridge, Watertown, Waltham, or the western Boston suburbs
- You value Harvard Medical School affiliation and university-hospital clinical standards
✗ Look elsewhere if:
- You’re seeking ketamine-assisted psychotherapy (KAP) with structured integration — McLean runs a medical-model program
- You want walk-in access or short intake timelines — academic medical centers typically have longer evaluation processes
- You need a downtown Boston location — McLean is in Belmont (western suburbs)

Patient Review

About McLean Hospital
McLean Hospital’s Ketamine Service operates from the main campus at 115 Mill Street in Belmont, Massachusetts, with the ketamine program housed in the ECT/TMS suite within the de Marneffe Building. McLean is a Harvard Medical School affiliate and one of the largest and most respected psychiatric hospitals in the United States.
The ketamine service is designed for adults with major depressive disorder, treatment-resistant depression, and bipolar depression. Treatment fits within McLean’s broader psychiatric continuum, which includes outpatient services, inpatient hospitalization, ECT (electroconvulsive therapy), and TMS (transcranial magnetic stimulation) — meaning patients can move between interventional protocols based on response and acuity.
Because of the academic medical center model, intake processes are more thorough than at standalone infusion clinics — psychiatric evaluation, treatment history review, and clinical eligibility screening are required before any ketamine dosing. For severe and complex cases this depth is the primary value; for patients seeking simpler outpatient access, the standalone Boston-area ketamine clinics in higher ranks of this list may be a better fit.
To begin intake at McLean’s Ketamine Service, call (617) 855-2364. The main hospital number is (617) 855-2000. Insurance coverage varies — confirm Spravato in-network status and IV ketamine self-pay rates during intake.
Patient Questions about McLean Hospital

What ketamine protocols does McLean Hospital offer?
McLean Hospital offers IV Ketamine + Spravato (Esketamine) — academic medical center program. Confirm specific dosing schedules during your consult.
Does McLean Hospital offer Spravato (esketamine)?
Yes — McLean Hospital offers Spravato, which means they’re FDA REMS-certified and maintain the required two-hour in-office monitoring window after each dose.
Does McLean Hospital offer ketamine-assisted psychotherapy (KAP)?
McLean Hospital operates a medical-model program. Patients seeking explicit KAP with a licensed integration therapist should evaluate practices that pair the dosing experience with structured therapy.
Is McLean Hospital suited for treatment-resistant depression?
McLean Hospital treats treatment-resistant depression. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates.
