Ms. Giselle Perez, MSN, PMHNP-BC
Psychiatric Nurse Practitioner
Giselle Perez is a board-certified psychiatric nurse practitioner and NYU-trained clinician specializing in anxiety and depressive disorders. She integrates medication management with evidence-based therapies—including CBT, CBT-I, and ERP—within a holistic, trauma-informed, and culturally responsive framework.
A proud Latina, Ms. Perez is fluent in Spanish and provides both therapy and medication management in Spanish, ensuring that patients can engage in treatment in the language and cultural context most comfortable to them. Her collaborative, compassionate style empowers patients to understand their symptoms, strengthen coping skills, and build lasting resilience.
In addition to her clinical work at Mensana Psychiatry, Ms. Perez continues to be actively involved in research and direct patient care at Mount Sinai Hospital, advancing evidence-based approaches to mental health treatment.
Giselle is excited to join Mensana Psychiatry and will be available for both in-person appointments at our 142 West 57th Street office and virtual sessions depending on patient needs.
Dr. Mensah continues to oversee all care and new referrals at Mensana Psychiatry. He will determine each patient’s fit and coordinate in-person appointments with Ms. Perez to ensure a cohesive and high-quality treatment experience.
