About Me
My approach to care is rooted in partnership, collaborating closely with patients and their families to develop personalized, holistic treatment plans that prioritize the patient’s best interests.
I enjoy my job as a family nurse practitioner because it allows me to care for entire families, build lasting relationships and ensure that every patient feels heard, valued and empowered in their health care journey.
I chose a career in nursing after over seven years of caring for critically ill patients, which ignited my passion for preventative and holistic care. This experience inspired me to become a nurse practitioner specializing in primary care, where I focus on keeping patients healthy and out of the hospital, with a particular interest in pediatrics and women’s health.
