Dr. Russell E. Brown

Direct Supervisor & Clinical Collaborator for Sabelle Mbye, Psychiatric Nurse Practitioner
(Dr. Brown does not see patients)

Dr. Russell E. Brown knew when he was just a high school student that he wanted to become a doctor; Particularly he wanted to learn everything that he could about the brain. The more I learned about the brain, the more fascinated I became—- how could this physical organ be the source of so many abstract ideas and create such a complex behavior?”

He began finding out as he earned his undergraduate degree at Vanderbilt University. He then earned a medical degree at Meharry Medical College completed a dual residency in Neurology and Psychiatry at the Tulane University Medical Center. He subsequently became dually board certified in Neurology and Psychiatry and has been in practice since 1995.

Dr. Brown specializes in assessing and managing the cognitive impairments, movement disturbances, and behavioral problems that occur as a result of developmental disorder trauma and especially aging. He has served as a neurologist and psychiatrist with the state’s Preadmission Screening and Annual Resident Review Program. He also serves as a psychiatrist for one of Georgia’s community service Boards and is currently a psychiatrist for one of the state’s Assertive Community Treatment teams, Psychosocial Rehabilitation centers, and Intensive Family Intervention programs.

Outside of his Practice Dr. Brown enjoys sailing and spending time with his son.
