Hello

I'm Antonia Keller. I'm passionate about helping individuals navigate life's challenges, especially those who've experienced trauma. I believe in creating a safe, respectful space for everyone, and I'm committed to understanding and honoring diverse experiences.

My Approach to Therapy

My approach to therapy is integrative and empowerment-focused. Drawing from nearly a decade of experience in community mental health, residential treatment, and outpatient therapy, I utilize a variety of evidence-based modalities, including CBT, DBT, and EMDR. I am also BCIA Board Certified in Neurofeedback, bringing a neurobiology-informed, body-based approach to nervous system regulation. My graduate training at Columbia University has grounded me in a person-centered, anti-oppressive framework, and I am dedicated to serving diverse populations. I am providing therapy under Trevor Hardcastle at Trevor Therapy & Associates, continuing my commitment to holistic and compassionate care.
