“My path to medicine was inspired by both my grandmother and mother, who were nurses. The many hours I would spend listening to their stories of providing patient care taught me the true human elements of medicine before I even began my medical training. With these life lessons from my family members, I embrace the true privilege of being part of a patients’ journey as a trusted and caring provider. My aim is to always keep our patients’ well-being and needs as the primary focus of our medical practice at CCRM Fertility.”
