Mary believes the human spirit is resilient. There are many challenges in the lifespan and self-care is paramount to success.

Mary provides psychiatric consultation and assessment and provides a pathway to change. Treatment may include medication management, therapy, and coping skills to assist with life challenges. Mary believes treatment is a partnership and believes in establishing mutually agreed upon goals.

Mary's process for working with patients begins with active listening. The assessment begins with the patient describing why they are seeking engagement in behavioral health treatment at this time. She will complete a psychiatric assessment and evaluation and establish mutually agreed upon goals for treatment. She offers medication management in conjunction with supportive therapy in 30-minute follow-up visits. Mary believes therapy and medication management if indicated together provides the best treatment outcomes.

Dr. Anil Joseph (AJ) Kulangara completed additional training in Psychiatry at the University of Washington after working primarily in women’s health, primary care, and military medicine as a Battalion Surgeon in the United States Army.  Following his military service, he trained in Psychiatry and served the mental health needs of our Veteran population.

Dr. AJ’s approach focuses on behavioral change, with medication management and supportive therapies serving as important (and often essential) adjuvants to optimizing mental health.

During your first meetings with Dr. AJ, you should expect a thorough evaluation of your clinical and social histories, as well as some introductory psychoeducation.  Following that screening, anticipate a discussion about his approach to your condition and an initial treatment plan.  Please feel free to bring up any questions or concerns at any time during this process, and note-taking is highly encouraged!
