I am dual board certified child, adolescent and adult psychiatrist. I see clients from age 12 and up. People come to treatment for all sorts of reasons — anxiety, depression, trauma, difficulty functioning at work or school, family conflict, challenges in relationships, low self-esteem, or simply a desire to learn more about themselves. As a child, adolescent, and adult psychiatrist with expertise in both medication management and psychotherapy, I can help patients develop a treatment plan that meets their needs. My style is guided by warmth and flexibility, with the goals of helping patients build insight and reduce symptoms. I create individualized treatment plans, assessing patients' goals, unique life experiences, and biological risk factors. While medication is useful in some cases, I am dedicated to helping my patients achieve lasting change through therapy as well.
