Explore This Residency Program

Mass General for Children (MGfC) is a children’s hospital within a world-class hospital. You can glimpse the depth and breadth of the patients by browsing the NEJM Case Records of the MGH. Leveraging the resources of this academic center, we are able to meet the diverse and unique learning, research and clinical interests of each of our incredibly talented residents. We do that within a close-knit community where resident support and mentorship are the cornerstones of a safe and productive learning environment. We as a program are invested in your individual and very personal experience of residency.

A Program Designed to Meet Your Individualized Needs

Academically, you are encouraged to design residency to meet your individualized needs. Rather than track residents into pre-defined pathways, we provide an opportunity for residents to explore their diverse interests and create their own path in residency, tailored to individual learning and career needs. Nine months of our residency training are determined by the resident. Residents choose even the “core” subspecialty months, rather than being simply scheduled for a required inpatient subspecialty month. Three months can be completely self- designed and we have had residents create incredibly rich and diverse rotations such pediatric care on a ship-hospital in Cambodia, comparative zoology with veterinarians, creating an emergency medicine curriculum for a brand-new residency program in rural Kenya and working with the Chief Quality Office of the hospital. At MGfC, one-size does not fit all and no two residents have the exact same training experience because no two residents are exactly the same.

MGfC is truly my ‘perfect fit’ – an incredible combination of clinical training, research opportunities, mentorship and focus on advocacy and caring for underserved populations.

A Program Committed to Diversity in All Aspects of the Word

MGfC strives to create a welcoming environment for its residents, faculty, staff, and patients. As an MGfC resident, you will have the privilege of caring for patients from a wide range of different racial, ethnic, and socioeconomic backgrounds at our main campus in Boston, our community health centers in Charlestown, Revere and Chelsea, and our affiliated community hospitals in Cambridge, Salem and Newton. MGH Chelsea Health Center, for example, cares for one of the largest and most diverse immigrant populations in all of Massachusetts! Our residents and staff come from many different backgrounds as well. We cannot think of a more perfect example than our own Pediatric Cardiology Department, where our staff of doctors is fluent in at least 5 different languages! MGfC is committed to recruiting and supporting a multicultural workforce of pediatricians to reflect our beautiful and diverse patient population. We are proud to collaborate with the MGH Center for Diversity and Inclusion as well the LGBT Employee Resource Group to promote and support underrepresented minorities in medicine throughout Mass General. Learn more about diversity and cultural competence at Mass General for Children.

Unparalleled Access to Senior Faculty

Our approach to mentoring is multi-faceted and is adjusted to the needs of the residents. Early in the intern year, residents participate in a mentorship workshop, complete mentoring self-assessments and have an in-person meeting with the chief residents who then work with the administrative team to carefully choose a mentor for each resident based on his/her self-identified interests and mentorship needs. There are group mentoring sessions designed to help residents choose scholarly projects and meet faculty doing research in a speed-dating type model. In the fall we have faculty and graduates come together in the evening for discussions over dinner about careers in acute care, hospital medicine, pediatric medical subspecialties and primary care. These are but a few examples of ways that we try to actualize the view of mentorship as a network, not a single person. At MGfC, not only are you working in a world-class environment, but you are working directly with the world-class leaders.

The Resources of Massachusetts General Hospital

Institution-wide resources within the Centers of Expertise allow trainees numerous opportunities including small group workshops, funding opportunities, and access to faculty leaders to refine their skills in the areas of Global and Humanitarian Health, Health Policy and Management, Medical Education, Patient Care Quality and Patient Safety and Research). Through initiatives such as this, you gain access not only to leaders in the field of pediatrics, but leaders in medicine across specialties and you become part of a broader community of graduate medical trainees at Mass General and Mass General Brigham. With the current speed of medical advancements, pediatrics can no longer stay insular and pediatricians must work in a broader context of medicine.

Life-Long Relationships

The motto of care for patients at MGfC is “Once we start caring, we never stop;” it is meant to reflect the value we place in caring for patients from in utero through birth, childhood, adolescence, adulthood and end of life. Once a patient at Mass General, always a patient at Mass General. Similarly, once you’ve joined the MGfC Residency family, you will always be a part of it. Graduates routinely return to “catch up” and share news of personal life events with program directors and faculty, but even more importantly, to receive mentorship as their careers unfold.. It is not a coincidence that many of our graduates over the years have stayed or come back to the MGfC at some point in their careers, and we take pride in the extended family of MGfC pediatricians we are creating.

One of the best things about the Mass General for Children Pediatric Residency is the people!

Each year, the residency program gets together for multiple exciting social activities, taking advantage of the incredible city of Boston around us as well as the beautiful New England countryside that surrounds the city on three sides.

Specifically, we have official activities hosted by our Wellness Committee throughout the year, most recently including peach and apple picking, wine tasting at Nashoba Valley Winery, drinks and appetizers at resident homes, picnics on the Charles River, bowling at Sacco’s with gourmet brick oven pizza, hiking on Mt. Wachusett,

social gatherings at the program director’s house, and many more. And there are plenty of unofficial resident-initiated activities throughout the year because we just like to hang out with each other outside of the hospital! We have so much fun together and we can’t wait to share it all with you!

Here are some quotes from current residents when they were asked about the Resident and Community life at MGfC:

“After my first day of intern orientation, my first thought was: wow, this decision was the best I've ever made.” –An MGfC Intern

“I love my life at MGfC! Residents ahead of me told me that they think of MGfC as another family and very quickly into intern year I understood exactly what they meant. These are my people. While so many fun memories have occurred outside the hospital (Red Sox games, many great meals out, resident happy hours, the list go on),

Fall fun!

it's the camaraderie within the hospital and within our program that makes it so special. This is a program that looks out for each other, lifts one another up when you need it, and at its core, helps you become the pediatrician that YOU want to be. Residency is a challenging time no matter where you go, feeling supported and valued and having a great time while doing so has made all the difference.” –An MGfC Junior Resident

“I love my co-residents because we always have each other’s backs- always lending a hand to help or support each other.” –An MGfC Senior Resident

As you can see, we love MGfC and hope you will too!

Resources for Applicants


The mission of the Mass General for Children Pediatric Residency Program is “To develop a diverse group of independent, innovative pediatric leaders through education and personalized mentorship in a supportive academic learning environment committed to excellence in family centered clinical care, research, and advocacy” We aim to train the next generation of pediatricians to practice innovative, evidence-based, multi-disciplinary medicine.

Our training program teaches residents to provide state-of-the-art patient care in diverse settings. At Mass General for Children (MGfC), residents work in "a hospital within a hospital," allowing them to leverage the resources of one of the oldest general hospitals in the world. While at our community hospital sites (Newton-Wellesley Hospital and Cambridge Health Alliance), they provide expert care in neighboring communities, in conjunction with MGfC specialists, close to patients’ homes, easing the burden of illness for families. It also affords residents the opportunity to learn how to recognize disease at its first presentation in the community and how to identify children who need an increased level of care. Our residents then learn how to care for children who require more specialized or intensive care when they rotate through our state-of-the-art 18-bed NICU and 14-bed PICU at MGfC. The MGfC Pediatric Emergency Department is also an incredible learning environment as the only center in the region with simultaneous designations as a level I adult trauma and burn center and level I pediatric trauma center.

Residency Program

The bedrock of general pediatrics training allows our residents to explore varied career opportunities and prepares them to achieve extraordinary professional success. Our graduates are some of the most trusted primary care providers in their communities and some of the region's top subspecialists. About half of our graduates continue their training in the most competitive fellowship programs in the country.

Our residents are a diverse group of extraordinary individuals who form a tight-knit community and excel in many areas above and beyond pediatrics. We have an extraordinarily active advocacy group that has been honored with several awards including the prestigious national Anne E. Dyson Child Advocacy Award. Many of our residents are involved in the MGfC Global Health Program. Residents enjoy each other's company outside of medicine as well (To learn more about resident life, visit the Resident Life and Community tab.)

We hope that you’ll enjoy learning more about our program. We look forward to learning more about you through the application and interview process.
