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. 

Therapy Approach


When working with clients who wish to address their trauma history, my therapy is largely influenced by Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) and Skills Training in Affective and Interpersonal Regulation (STAIR).  Through psychoeducation, relaxation techniques, and learning to identify and successfully manage emotions and cognitions, clients 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 trauma manifests differently depending on one’s age and developmental stage at the time of the trauma as well as at the time of treatment.  Throughout treatment 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.

With regards to family work, I lean on Structural Family Therapy and Family Systems Theory, understanding that family members cannot be looked at as isolated individuals but rather as part of a living, changing family unit.  Therefore, conflicts are not caused by one member but are influenced largely by the interactions between and history of all of those within the family.  When working with families, I am available to help with such concerns as addressing and resolving interpersonal conflict between members, managing life transitions, and developing more successful discipline strategies.
