Alisa Horwitz, Ph.D., Licensed Clinical Psychologist

I am a licensed clinical psychologist and received my Ph.D. in Developmental Clinical Psychology from Bryn Mawr College in Pennsylvania.  Prior to that, I obtained my BA from Swarthmore College with a major in psychology.  My professional experience has centered largely on providing individual therapy with children, adolescents, and adults who have experienced trauma.


I was born in central California but spent much of my childhood moving around the country with both of my parents and then, following divorce, with my mother.  Eventually, she and I moved back to northern West Virginia, where she grew up and her family continues to reside, and I remained there until leaving for the Philadelphia area to attend college.

I completed my Ph.D. in Developmental Clinical Psychology in 2010, during which I focused on family systems, child and adolescent development, and school psychology assessments and interventions. 

While completing my dissertation, I began working as an evaluator for a community mental health organization in Philadelphia that assessed and treated children and adolescents who had been affected by sexual abuse and other traumas.  I extended my involvement via a full-time psychology internship and then, following my graduation, I remained as a therapist before leaving to move to Seattle.  My experience helped clarify my primary interest in supporting those who have experienced various levels of trauma. 


I currently provide individual therapy to adolescents and adults who have experienced trauma, specifically but not limited to sexual assault or childhood sexual abuse, as well as provide individual therapy focusing on managing symptoms of depression and anxiety.

I may use various therapeutic methods during treatment as the need arises, most from a trauma-focused and/or cognitive-behavioral lens.  When working with clients who wish to address their trauma history, my therapy is largely influenced by a belief that trauma is best addressed by first focusing on psychoeducation, relaxation techniques, identification of relational patterns, and learning to identify and successfully manage emotions and cognitions.  During these early sessions, clients work to develop skills that are then available for them to use while processing the trauma(s).   

I approach each client through a developmental lens, understanding that therapeutic concerns manifest differently depending on one’s age and developmental stage at the time of treatment, as well as at the time of the trauma should that be the primary therapeutic concern. 

Throughout treatment, regardless of primary concern, I work with the client to cultivate and/or maintain strong outside social support, which coincides with one of my core therapeutic beliefs that successful progress is only as sustainable as the level of support that a client has outside of session.
