Dr. Sascha Griffing (she/her/hers) has been providing comprehensive therapeutic services to youth, adults and families for nearly 25 years.  She gained a wealth of experience working within New York City systems (including the legal, mental health and child welfare systems) with clients who have experienced significant trauma, often exacerbated by racial and social injustices.  She has been inspired by the ability of her clients to thrive despite adversity and this work has enhanced her understanding of the skills and characteristics that promote resilience.  These skills can be more broadly applied to managing challenging life circumstances and stressors as well as conditions like depression and anxiety. Dr. Griffing has been trained in several evidence-based cognitive behavioral and trauma-focused interventions as well as psychodynamic psychotherapy.  She takes a flexible and collaborative approach and works to empower clients to reflect on past experiences and behaviors, consider their priorities and values, engage in meaningful relationships and self-care, and build skills to respond flexibly to stress.
