My name’s David Flack. I’m a Licensed Mental Health Counselor (LMHC), Substance Use Disorders Professional (SUDP), and Approved Clinical Supervisor — with offices in the Fremont neighborhood of Seattle and Tukwila, Washington.
Since 2002, I’ve been providing therapy for teens and emerging adults with a wide variety of mental health and behavioral concerns — focusing primarily on trauma, substance related issues, problematic pornography use, LGBTQ+ topics, and oppositional behaviors. For more, go to Counseling.
In addition to my clinical work, I regularly offer well-received professional development programs for therapists and other helping professionals — covering topics such as facilitating change, treating trauma in teens, addressing substance use, and engaging resistant teens. For more, go to Training.
SEEKING SERVICES?
I have the following openings for weekly in-person sessions:
Fremont: None. I anticipate openings in 4-6 weeks.
Tukwila: Tuesdays 3:00pm. Tuesdays 4:00pm.
