Business Description : Repose is a women-owned psychotherapy and somatic wellness company based in New York, serving clients across New York State, New Jersey, and Connecticut. Founded by licensed psychotherapist Mary Breen, LCSW, SEP, Repose operates a multi-site group practice and somatic studio focused on advancing nervous-system-informed care as a core standard in mental health treatment. Repose provides outpatient treatment for trauma, anxiety, grief, relationship challenges, and complex life transitions. Clinical care integrates evidence-based somatic modalities including Somatic Experiencing® and Eye Movement Reprocessing Desensitization (EMDR) alongside parts work and relational psychotherapy. This integrative approach reflects a growing body of clinical research demonstrating that lasting psychological change requires direct engagement with the nervous system, not cognition alone. Beyond direct client care, Repose functions as a clinician training and development platform, investing heavily in advanced education, supervision, and operational systems that support high-quality, consistent delivery of somatic-based treatment. Through Studio by Repose, the company also expands access to nervous-system-informed practices in non-clinical settings, bridging the gap between mental health treatment and embodied wellness. Repose is built as a founder-led, values-driven business with disciplined operations and a long-term vision: to help establish somatic therapies as a gold standard in mental health care by pairing clinical rigor with scalable, ethical business infrastructure.
