Doctor & Nurses

Dr. Anson Liu

Assistant Medical Director,


Prior to starting medical school, I completed bachelor's degrees in biology as well as economics and finance. I attended medical school at the University at Buffalo and completed my residency in psychiatry and fellowship in child and adolescent psychiatry at the University of Maryland Sheppard Pratt program. I work with patients of all ages and treat depression, anxiety, mood disorders, PTSD, and ADHD with a combination of medications and psychotherapy. In my free time I enjoy lifting weights, playing sports, traveling, and spending time with my family.

Dr. Charles Oseroff
Medical Director,

I am a board certified child, adolescent, and adult psychiatrist, who has been practicing psychiatry for 30 years in the Baltimore area. I treat patients of all ages and I specialize in working with children/ adolescents who have ADHD, those who have a history of trauma, as well as individuals that suffer from anxiety and mood disorders. I prescribe medication when indicated and provide ongoing consultation to the treatment team. In my free time, I enjoy sailing and playing the mandolin.

I originally graduated from the University of Maryland, College Park with my bachelor's degree in psychology and criminal justice. I then went on to earn my master's degree through the Clinical Nurse Leader program at the University of Maryland School of Nursing. I practiced as a registered nurse in the psychiatric emergency services at the University of Maryland Medical Center for over six years and returned to the University of Maryland to obtain my post-master's certificate in advanced practice nursing. I am a member of the American Psychiatric Nurses Association, Nurse Practitioner Association of Maryland, and Sigma Theta Tau Honors Society of Nursing. In my free time I enjoy seeing my family, taking walks, playing sports, catching up on my favorite shows, and listening to music.
