David Walter, D.O.

Greater Portland DBT is a collaborative group of independent therapists who are invested in providing outstanding Dialectical Behavioral Therapy services to the greater Portland, Maine community. Having completed my DBT intensive training in 2003, I am experienced in providing both individual DBT and skills training, and offer medication management to young adults and teens participating in DBT. I also lead a support group for patients with Crohn’s disease and Ulcerative Colitis and offer psychiatric care to those suffering with chronic illness.
