Patient comments emphasize her knowledge, compassion, and ability to create a safe, inclusive environment, particularly for LGBTQ+ patients. For instance, a review from June 4, 2025, praised her for being “a wholehearted doctor” who listens and respects patient needs, while another from May 9, 2025, highlighted her detailed explanations and patient-centered approach. These reviews, dated as recent as June 2025, suggest ongoing patient engagement, though the exact timing of these services needs verification given her registration status.
Current Practice Status and Contact Information
Dr. Mastouri’s contact details include her practice address at 408-3101 Bloor Street West, Toronto, ON M8X 2W2, and a phone number, 647-286-9896, associated with her clinic, NewDermaMed Laser Clinic. However, a critical point to note is her registration status with the College of Physicians and Surgeons of Ontario (CPSO). Her last individual certificate of registration, an Independent Practice Certificate, was issued effective October 10, 2014, with no explicit expiration noted in the records. However, the certificate of authorization for her professional corporation, “Dr. Mastouri Medicine Professional Corporation,” has been inactive since October 30, 2021. This distinction is important: the inactive status applies to her corporation, not necessarily her individual license to practice, which may still be active. Given this complexity, potential patients are advised to confirm her current ability to practice by contacting the CPSO or her clinic directly.
This nuance is significant, as it suggests she might still be providing services individually, but the inactive corporate authorization could impact her ability to operate through her clinic. The CPSO’s role is to regulate medical practice in Ontario, and their records indicate she was educated and experienced in her areas of practice, but the exact implications of the inactive status require further clarification .
Specialties and Approach to Care
Dr. Mastouri’s practice is characterized by a holistic, interdisciplinary approach, focusing on personalized, preventive, and predictive healthcare. Her interest in skin disorders, aesthetic medicine, and women’s health aligns with her role at NewDermaMed, where she aims to help clients achieve optimal health and well-being. This approach is reflected in patient reviews, which often mention her ability to address both medical and emotional needs, fostering a collaborative, patient-centric culture.
Dr. Negin Mastouri appears to have been a highly regarded family physician in Toronto, with a robust educational background and positive patient feedback, particularly in infectious disease, aesthetic medicine, and women’s health. However, her current practice status is uncertain due to the inactive certificate of authorization for her corporation since October 2021, while her individual practice certificate seems to remain active from 2014 records. Given this, anyone seeking her services should verify her current registration and ability to practice, ensuring compliance with Ontario’s medical regulations. This report aims to provide a comprehensive overview, balancing patient experiences with professional details to inform potential patients and stakeholders.
