Over the last decade, my focus has been directed towards researching treatments for a variety of the most common psychiatric disorders – Depression, Anxiety, and various Mood Disorders. My treatment philosophy recognizes that pharmacological therapies for these conditions, should be aimed at an individual’s particular genetic makeup. In my experience, when this approach is used in combination with transcranial magnetic stimulation, you find patients achieving higher rates of remission for longer periods of time.
