Director of Professional Affairs (DPA)

Samantha Slaughter, Psy.D., is a licensed psychologist in Washington State. She served as WSPA's Federal Advocacy Coordinator from 2012 to 2018 and was one of 3 qualified candiates iterviewed and selected to replace retiring DPA, Dr. Homans, starting January 1, 2019. In her private practice, her overarching focus is working with individuals facing the challenges of trauma, life transitions, grief, and loss. Her main goal is looking at providing integrative work; Dr. Slaughter will work together with you to understand what approaches to therapy will be most effective and empowering. 

The Director of Professional Affairs (DPA) is required by APAPO to be a licensed psychologist. However, the job descriptions of the 16 current DPAs around the country are different and tailored to the needs of each state association with whom we work. The DPA attends the annual Professional Leadership conference sponsored by APAPO.

In Washington State the DPA is first and foremost responsible for answering all member questions or concerns regarding clinical practice, whether the psychologist is working in independent practice, group practice, clinics or medical centers, or in public systems of care. The DPA also serves as a resource to our members with regard to all professional questions.

The DPA works closely with the WSPA lobbyist with regard to legislation affecting the practice of psychology, the psychologist licensing statute, or any legislation involving access to and delivery of mental health services in Washington State. To this end, the DPA monitors all relevant legislation, collaborates with other associations and groups with regard to specific bills, testifies before Legislative committees and meets with Legislators about bills of importance to psychology, and provides input to state agencies on significant policy matters. The DPA also provides support to the WSPA lobbyist and the board of the United Psychologist PAC.

The DPA works in collaboration with the Executive Director of WSPA to develop continuing education and professional development programs for our members, as well as providing support for graduate student members and early career psychologists. The DPA also collaborates with the Executive Director with regard to communications about professional affairs and the practice of psychology in Washington State to our members. This includes regular postings in the WP as well as periodic broadcast emails about emergent issues.
