Greenbrook TMS
United States · Toronto, Ontario, Canada
Greenbrook TMS Inc. operates the Greenbrook Mental Wellness Centers network of interventional psychiatry clinics in the United States. Clinics provide NeuroStar transcranial magnetic stimulation and, at selected locations, SPRAVATO esketamine treatment. Its neuroscience relevance is clinical neuromodulation and psychiatric care; it is a care-delivery operator, rather than the manufacturer of NeuroStar or an AI software vendor. The Ontario legal company was incorporated in2018 around an existing US treatment-center business. Neuronetics completed its acquisition on December9,2024, making Greenbrook a wholly owned subsidiary; the Greenbrook clinical brand continues while its former public listing is historical. Current public clinical leadership includes Chief Medical Officer Geoffrey Grammer and Executive Vice President/General Manager Cory Anderson. Its live care directory lists clinicians and regional operators, including medical directors, psychiatrists, nurse practitioners and physician assistants; some clinicians also run external practices or work as contractors. Madryn financed Greenbrook through funded senior loans and convertible notes. The acquisition exchanged shares after debt conversion; that exchange is not new issuer cash.
