I believe in the prevention of disease and the promotion of healthy lifestyles for all children through education and dedication to quality care.

I like to treat each patient and family as individuals. I enjoy earning their trust and getting to know them as well as helping to navigate their child’s successes and challenges. I take pride in making sure we have full and open communication in our visits and your visit never feels rushed. My mission is to provide our patients with the best and most comprehensive pediatric care possible from birth until 21 years of age. I adhere to the “Golden Rule” in my life and practice which is the principle of treating others as one wants to be treated. Outside of work I enjoy exercising, horse back riding, and spending time with my family. I am an avid animal lover and we have many animals in our family.

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.

Dr. Meredith Faggen, Medical Director of Medical Oncology at Dana-Farber/Brigham Cancer Center at South Shore Health

My mission as an emergency department physician is to provide timely and excellent care to patients while helping them through what are likely very stressful and difficult emergency situations.

I grew up in southern New Hampshire and attended Providence College in Rhode Island. I then obtained my MD at the University of Connecticut. I completed my emergency medicine residency at the University of Cincinnati and while I loved the Midwest, I always planned to come back to New England and was happy to move to the South Shore. In my free time I enjoy hiking, skiing, and spending time with family and friends.

I love caring for children and their families, whether it be supporting parents as they learn how to care for their newborns or helping a sick child recover from an acute illness. I believe in shared decision-making and incorporating each family's individual needs and goals into their child's care. Outside of work, I enjoy spending time with family, running, and traveling.
