Greenbrook TMS in Baltimore: Specialized Brain Stimulation for Treatment-Resistant Depression
Greenbrook TMS Neuro Health Centers is a psychiatric practice focused on transcranial magnetic stimulation, a procedure used primarily for major depression that has not responded to medication or therapy. The Baltimore office operates as part of a larger clinic network and serves patients who have exhausted conventional psychiatric treatments or cannot tolerate antidepressant side effects.
What TMS actually treats
Transcranial magnetic stimulation uses magnetic pulses to stimulate nerve cells in the brain regions associated with mood regulation. The FDA approved TMS for major depression in 2008 and for obsessive-compulsive disorder in 2018. Greenbrook markets TMS primarily to patients with treatment-resistant depression, defined as failure to improve after two or more medication trials. The procedure does not involve surgery, anesthesia, or hospitalization. Sessions last 19 to 37 minutes depending on the TMS protocol used, and patients sit awake in a reclining chair while a magnetic coil is positioned against the scalp.
Greenbrook also offers psychiatric medication management alongside or in place of TMS. This dual-service model means patients can be evaluated, treated with TMS, and managed by a psychiatrist without referral to another provider.
Treatment protocols and what to expect in cost and timeline
Standard TMS treatment at Greenbrook typically runs 20 to 30 sessions over 4 to 6 weeks, three to five days per week. The total cost ranges from $10,000 to $15,000 for a full course of treatment, though this varies by the specific protocol (standard, intensive, or maintenance). Verification recommended: insurance coverage differs significantly by plan and state, and out-of-pocket responsibility should be confirmed directly.
Maintenance TMS—less frequent sessions after initial response—costs roughly $1,500 to $3,000 per month. Some patients achieve results within the first two weeks; others require the full course before improvement becomes apparent.
Greenbrook accepts major insurance plans, including Aetna, Cigna, United, and Medicare, though coverage determinations must be confirmed before starting treatment. Out-of-pocket patients should ask whether the practice offers self-pay discounts or payment plans.
How Greenbrook compares to Baltimore psychiatry options
Baltimore has few dedicated TMS providers. Sheppard Pratt Health System, a regional psychiatric hospital, offers TMS but embeds it within inpatient or intensive outpatient programs; patients referred there enter a broader treatment ecosystem rather than receiving TMS as a standalone service. University of Maryland Medical Center's psychiatry department has also begun offering TMS, primarily to existing patients or those referred from primary care.
Choose Greenbrook if you want a practice centered on TMS with embedded psychiatric medication management and no requirement to enroll in an inpatient program. Choose Sheppard Pratt or UMM if you need comprehensive psychiatric inpatient or residential care alongside TMS, or if your referral has already routed you there.
Ketamine infusion therapy, available at select psychiatric clinics in the Baltimore area, offers an alternative for treatment-resistant depression with a faster onset (sometimes within hours to days) but requires anesthesia monitoring and typically costs $300 to $500 per infusion session (four to six sessions standard). TMS is non-invasive and requires no sedation, making it suitable for older adults or those unable to tolerate anesthesia.
Who is suited and who is not
TMS works best for adults with major depressive disorder who have failed at least one antidepressant trial. It also suits patients who experience intolerable side effects from medication (weight gain, sexual dysfunction, sedation) or are pregnant and want to avoid medication exposure. Teenagers and adults with bipolar disorder may be candidates, though bipolar depression requires modified TMS protocols and closer psychiatric oversight.
TMS is not a first-line treatment. Psychiatrists typically recommend starting with therapy and medication, then considering TMS if those fail. Patients with metal implants in the head (except titanium dental work), a history of seizures, or untreated psychosis are generally not candidates. A psychiatric evaluation determines eligibility.
What happens on the first visit
The first appointment includes a 60-minute psychiatric intake, depression severity assessment using standardized rating scales, review of past medication trials, and a screening for contraindications. If cleared for TMS, a technician conducts a "motor threshold" test, in which the magnetic coil is positioned to determine the lowest stimulation level that triggers a finger twitch; this establishes the dose for subsequent sessions. The actual first TMS session often occurs the same day or within a few days.
Patients drive themselves to appointments; TMS does not impair cognition or cause sedation. Most work or manage other responsibilities on the same day as treatment.
Hours, location, and logistics
Greenbrook operates clinic hours Monday through Friday, typically 8 a.m. to 5 p.m., with limited weekend availability depending on the location. Verification recommended: specific hours and current staffing should be confirmed by phone, as TMS clinics sometimes adjust schedules based on patient volume.
The Baltimore office is located in a medical office building with accessible parking. Public transit access depends on the specific address; the practice can provide transit directions when scheduling. Appointments should be booked in advance; same-day walk-in treatment is not available.
Greenbrook TMS fills a narrow but important gap in Baltimore psychiatry: it offers focused, evidence-based treatment for a population often told no other options remain, and it does so without requiring hospitalization or the time commitment of ketamine protocols.
