Greenbrook TMS, trading under the symbol GBOKF on the OTC Markets, is a U.S.-based healthcare company specializing in neuromodulation services. The company focuses on delivering transcranial magnetic stimulation (TMS) therapy, an FDA-cleared, non-invasive procedure designed to treat major depressive disorder and related neuropsychiatric conditions. Greenbrook TMS operates through a combination of company-owned and franchised clinics, offering patients an alternative to traditional pharmacological treatments.
At the core of its offering, Greenbrook TMS provides TMS therapy using advanced magnetic stimulation devices sourced from leading medical technology manufacturers. Patients typically receive daily outpatient sessions over several weeks, during which brief magnetic pulses target specific brain regions associated with mood regulation. The company also delivers training and support to clinical staff, ensuring consistent treatment protocols and patient care standards across its network of facilities.
Greenbrook TMS has expanded its footprint across multiple U.S. states, serving communities through more than two dozen clinic locations in both metropolitan and suburban markets. The company’s hybrid model combines direct operation of certain centers with a franchise program that enables local practitioners to leverage Greenbrook’s brand, clinical expertise and administrative infrastructure. This approach supports rapid market entry while maintaining operational oversight and quality control.
Since its inception, Greenbrook TMS has focused on building a scalable platform to meet growing demand for non-drug depression therapies. The company continues to explore strategic partnerships and technology collaborations to enhance its service offerings, while adhering to evolving clinical guidelines for neuromodulation treatments. By fostering connections between patients, physicians and mental health specialists, Greenbrook TMS aims to advance the adoption of TMS as a mainstream therapeutic option.
