Dr. St John was an early adopter of transcranial magnetic stimulation (TMS therapy). Because she has been performing TMS since 2013, nearly 10 years, she has extensive experience performing thousands of treatments on patients with depression. She sub-specializes in the evaluation and treatment of depression and is an expert in the field. She elected to further her training by undergoing a week-long training in advanced TMS topics at the Berenson-Allen Center for Neuromodulation at the Harvard Medical School in Boston, MA in 2015 and obtains routine continuity medical education on current research in TMS through her membership with the Clinical TMS Society. She and her staff have developed a highly effective system for obtaining insurance approval for patients Dr. St John considers to be candidates for TMS. Lastly, patients routinely rave about Rachel and the care she provides during their treatments.
