Assistant Director & Senior Clinician

Ashling brings over a decade of clinical experience to her role of Assistant Director and Senior Clinician at City Behavioral Health. Ashling has worked extensively with adolescents, emerging adults, and adults navigating complex mental health challenges across outpatient, intensive outpatient, and partial hospitalization settings.

A highly adept and empathetic therapist, Ashling recognizes the transformative potential of the therapeutic alliance and its reparative effects.
