Meet the YES team

David W. Downing

YES CEO David Downing

David W. Downing (he/him), MS, LMHC, CMHS, joined YES as its Chief Operating Officer in 2006 and has been the Chief Executive Officer (CEO) since May 2020.

David is a Licensed Mental Health Counselor and Child Mental Health Specialist with over 30 years of leadership in the non-profit sector. David holds a Master’s degree in Psychology from Seattle Pacific University and a Certificate in Fundraising Management from the University of Washington. David currently serves on the board of Eastside Pathways and, in the recent past, has also served on the boards of the Alliance of Eastside Agencies (AEA) and the National Alliance of Mental Illness (NAMI) in Washington State. David has been nationally recognized by the Child Welfare League of America for his work and advocacy for youth in the child welfare system (Outstanding Direct Service Worker Award for the Western United States).

Over the years, David has made changes and introduced programs and partnerships to increase both the depth and breadth of YES services. He transitioned YES’ behavioral health services from a traditional supportive listening model to one grounded in evidence-based practices such as Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT). He removed barriers to behavioral health access by developing strong partnerships with the Bellevue and Lake Washington school districts, the cities of Bellevue, Kirkland, Redmond, and Sammamish, and a wide variety of community locations.

In response to a significant rise in the acuity of youth mental illness and substance use, David oversaw the integration of psychiatric services at YES, including evaluations, medication management, and physician-level guidance on treatment. Designed to prevent the development of future problems, under his direction, YES launched an early childhood behavioral health program, adding evidence-based services to help the youngest children and their caregivers. In March 2020, due to the COVID-19 health crisis, David led the rapid transition of YES services to a TeleHealth virtual platform, helping to ensure continued access and continuity of care.

David has been featured in both 425 Magazine and 425 Business (magazine), most recently in the May 2024 edition of 425 Magazine. An opinion piece he recently wrote was featured in the April 29, 2024 Seattle Times.
