Biography

I have years of experience treating depression, anxiety and panic attacks, bipolar disorder, PTSD, ADHD, and OCD. Most recently, I worked for Life Stance Health, an outpatient telehealth company, where I treated patients between the ages of 18–65 with both medication management and therapeutic interventions.

I am board-certified by the American Board of Psychiatry and Neurology in General Adult Psychiatry. I completed my psychiatry residency training at Howard University Hospital and Saint Elizabeth's Hospital in Washington, DC, where I was voted Chief Resident. I went on to serve as Vice Chair of the Department of Psychiatry at Adventist HealthCare in Maryland, where I worked in both an administrative and clinical role treating adults in inpatient settings. Additionally, I served as a Clinical Instructor of Psychiatry at Georgetown University School of Medicine, teaching medical students about the art of medicine. I received my undergraduate degree in Neuroscience from the University of Michigan and my medical degree from Xavier University School of Medicine.
