Dr. Sarah Fraser

Sarah Fraser, PsyD is a licensed clinical psychologist who earned her doctorate at Yeshiva University and completed her postdoctoral fellowship at the William Alanson White Institute. She sees psychotherapy as a collaborative process to help individuals gain a fresh perspective on their lives, recognize repeating patterns in their behaviors and relationships, and find new solutions for old problems. Her approach is psychodynamic and eclectic, balancing both depth and real-world focus to address the unique needs of each patient at the intersection of their physical, mental, internal, external, interpersonal, and sociopolitical spheres of experience. Dr. Fraser’s passion is working with individuals who find themselves outside of the narrow band of supposedly “normal” identity and desire, including people who are “kinky”/involved in BDSM, polyamorous, in open relationships, queer, gender non-conforming, non-binary, and/or trans* (transitioning or not transitioning). She endeavors to use her concentrated graduate study and clinical experience in these areas to provide a warm, open, and supportive space to facilitate exploration
