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 provided therapy for teens and emerging adults with a wide variety of mental health and behavioral concerns — focusing on trauma, depression, substance related issues, problematic pornography use, and LGBTQ+ topics. 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. Popular topics include facilitating change, treating trauma in teens, addressing substance use, and more. For more, go to Training.
