About me
My clinical experience includes work in outpatient substance use treatment across higher levels of care, including PHP and IOP, as well as providing individual psychotherapy in a private practice setting. I have worked with adult clients in both in person and virtual formats. This range of experience informs my thoughtful, grounded approach to treating complex, co occurring mental health concerns.
I work with adolescents and adults experiencing eating disorders, substance use concerns, and related mental health conditions, including anxiety, depression, bipolar disorder, and personality disorders. I also support individuals navigating relational dependency, perfectionism, and identity development challenges. I work within Columbus Park’s evidence based eating disorder treatment framework, with specialized training in Enhanced Cognitive Behavioral Therapy for Eating Disorders (CBT-E) and close mentorship from our Clinical Director, Melissa Gerson, LCSW.
My clinical approach is integrative and relational, incorporating Cognitive Behavioral Therapy, Dialectical Behavior Therapy, Acceptance and Commitment Therapy, Motivational Interviewing, Gestalt therapy, and mindfulness based interventions. I work collaboratively with clients to identify patterns that interfere with recovery and values based living, while offering structure, curiosity, and emotional attunement.
I bring warmth, authenticity, and a steady presence to my work. I am especially passionate about supporting individuals whose struggles with eating, substance use, or emotional regulation have disrupted identity formation or a sense of agency. I help clients move toward a more connected, self directed, and meaningful life.
