Welcome to my psychiatry practice. My name is Sanh Nguyen, and I am a board-certified psychiatrist with over 11 years of experience.
I am trained in Osteopathic medicine and have a holistic and integrative approach to psychiatry practice. I believe in treating the whole person, not just their symptoms. I offer both short-term and long-term psychotherapy in addition to psychopharmacology management. My goal is to help my patients achieve their best mental health by considering all aspects of their well-being, including their physical, emotional, and spiritual health.
I have significant experience working with patients who suffer from post-traumatic stress disorder (PTSD), substance use disorders, depression, anxiety as well as bipolar disorders and psychotic disorders. My approach to psychiatry is collaborative and patient centered.
Thank you for considering me as your psychiatrist. I look forward to the opportunity to work with you and help you achieve your best mental health.
