Prior to joining Cohasset Pediatrics I practiced pediatrics south of Boston for nine years and was Chief of Pediatrics for four years within that practice.  

I received my undergraduate degree in Drama from New York University’s Tisch School of Arts.  Working as an actress afforded me the opportunity to travel professionally and experience life as a performing artist in New York City, Los Angeles and London. While working in show business was certainly exciting, I found my true calling working as a physician partnering with parents to help provide the best medical care for their children.

When not at work, I love spending time with my husband and two children and enjoy singing when I get the chance.

I grew up on the South Shore and attended Holy Cross for college where my concentration was pre-medical sciences and sleep research. During summers in college I worked as an EMT and following college I worked in a collaborative Brigham and Women’s Hospital/Harvard Medical School lab studying allergy and asthma. While at the University of Massachusetts Medical School and Lahey Clinic my focus was on primary care internal medicine. In 2006 I was the recipient of the “Patient Care Award” which is Lahey Clinic’s highest physician honor. I joined South Shore Medical Center in 2006.

I graduated from Colegio Nacional de San Isidro in Buenos Aires, Argentina and completed my medical degree at Buenos Aires University School of Medicine. My surgical and urological residency were spent at the Hospital Italiano in Buenos Aires. I was an attending Urologist at Hospital Roffo in Buenos Aires until I came to the United States. At that point I was a Urology Fellow working on a research project at the Children’s Hospital and Harvard Medical School in Boston. I completed his American residencies in urology and surgery at the University of Massachusetts.

I enjoy spending time with my wife and three children.

I want each patient I care for to feel heard, safe, well-informed and active participants in their healthcare.

Midwifery has been an (almost) lifelong passion of mine. I saw my aunt give birth to my cousin when I was 10 years old and knew instantly that caring for women and babies was what I was meant to do. I started as a labor and delivery nurse in 2011 and completed midwifery school in 2015. I have attended births in the hospital and home setting. I love caring for women in pregnancy and all other stages in their lives. In my free time, I enjoy hanging at our family beach house on the Jersey Shore, snowmobiling in Pittsburg, NH and spending time with my husband and 2 daughters. 

My mission is to guide and empower patients as active participants in their care to promote a healthy lifestyle and prevent disease throughout their lifespan.

As a Primary Care NP, having the ability to form lasting relationships with my patients is what I find especially unique and rewarding. I highly value a holistic approach to patient care, as I believe comprehensive health expands beyond the physical aspects. I want to work together with each patient, since more successful outcomes are achieved through a mutually agreed upon and individualized plan. I like to practice what I preach by living a healthy, active lifestyle outside of work that includes running, yoga, hiking, spending time with family and friends, and traveling.

My job is ultimately about the trust that comes from a long-term relationship.  I am honored that people choose me to care for them and their extended families, and I do my best to give thoughtful and evidenced based advice.  Each of us has unique goals for our long term health, and I really enjoy giving people guidance in this realm.  I also enjoy the challenge of my work.  Each day is extremely diverse and forces me to stay continually current.  When I am not at work, I love competing in triathlon and cycling events, skiing, travel, and being outside.  I also adore being a father to my three daughters.
