I care for women throughout their lives—from adolescence through adulthood. I especially enjoy building long-term relationships and being with my patients through each step of their lives. From routine gynecological care to preconception, pregnancy, post-partum and menopause, I am here for my patient throughout her life. I chose OB/GYN as my specialty for the diversity of practice. It involves medical care, surgical care, and delivering babies. 

My parents inspired me—my father was a surgeon and my mother a nurse. I initially wanted to forge a different path and received my bachelor’s degree in Economics. I worked in financial public relations for a short while, but I kept coming back to what really interested me: medicine. I eventually went back to medical school to pursue my true passion. Outside of work, I love being outdoors—hiking, biking, boating, paddle boarding, and snowboarding. I also love to travel and spend time with my family and beloved dog and in quieter times enjoy reading and knitting.

As a Maternal-Fetal Medicine physician, I am dedicated to caring for women and families navigating high-risk and medically complex pregnancies with expertise, compassion, and individualized attention. 

I strive to integrate evidence-based medicine with a holistic approach that recognizes the physical, emotional, and social factors that shape each patient’s experience.
