I enjoy the challenge of the diagnostic process of medicine, which is one of the many reasons I have chosen to work as a nocturnist, which is a hospital-based physician who works overnight. In my free time, I've been known to read books about the American Revolution and Colonial Period, or attend hard rock/metal concerts. Also, '90s music is in my head all of the time.

Before becoming a midwife, I was a labor and delivery nurse at South Shore Hospital for 14 years. Women's health is my passion, and it is a privilege to return as a provider. I am honored to care for women during pregnancy, labor, birth, and throughout the lifespan. My care focuses on a team approach with the patient as the leader. Beyond midwifery, I enjoy hiking and yoga and love being a mom most of all.     

My treatment philosophy is to help educate individuals on their role in disease prevention and develop relationships with patients—working as a team to manage both chronic and acute health issues. I believe that each individual has their own unique set of circumstances that influence their health and working together to overcome barriers is an essential part of providing healthcare. I consider it a privilege getting to know patients and families and always look at the big picture when caring for individuals. Outside of work I love spending time with my family, going to the beach, gardening and hiking. I am teaching myself how to ice skate so I can play hockey with my boys!
