Lucy Gleysteen




Lucy strives to cultivate a therapeutic environment that facilitates healing, exploration, and connection. Their approach is gentle, client-centered, and non-judgmental. They are grounded in a psychodynamic and trauma-informed framework that honors the ways that people have survived the past and how that impacts the present. Lucy’s intention is to understand the complexities of each person. They recognize the way that oppression and social context are inextricably linked to mental health. They use a social justice lens to collaborate with clients in exploring the relationship between their concerns and their environment. 


Since 2014 their work has involved increasing access to health and mental health information. They worked at Philadelphia FIGHT in the education department before starting their MSW field placements. Prior to their time at Walnut, they interned and then worked at Penn Behavioral Health's Outpatient Psychiatry program as a psychotherapist. Lucy works with teenagers and adults experiencing a range of concerns including complex trauma and PTSD, anxiety, depression, gender and sexuality identity development, and relationship concerns.
