Uncommon Opportunity

Commonwealth is a co-ed independent day school welcoming curious, highly motivated students in grades 9–12. Our close-knit community thrives on making meaningful intellectual and personal connections, while tapping into the opportunities surrounding our home in Boston’s Back Bay.

Meet Faculty and Students

It’s incredible to be part of a community that is this close. I know it's a little bit cliché, but it's just a really cool feeling to be able to turn the corner and see someone and immediately gravitate to them and talk about whatever. There's never, never a dull day.

There are so many different kinds of people at this school with so many different outlooks in life. Even if you disagree with someone's views, I feel like here you can still have a respectful conversation. And I think that's a really important life skill: to be able to talk to people you don't necessarily see eye-to-eye with.

Commonwealth has opened up a path to relationships with both students and teachers that I hadn't really seen before. I have teachers that I can rely on, that I can ask questions of and meet with, and I want to continue having those relationships in the future with my professors in college and bosses at jobs. Commonwealth really built a strong foundation for that.

Really exciting classrooms are where the student is part of the circuit and the electricity is jumping between them and the sources and the teacher. At the beginning of the Enlightenment unit, instead of saying, 'This is what the Enlightenment is.' We say, 'Here's Newton's laws of natural philosophy. Here's a poem about sinful bees. Here’s a little Montesquieu with a little Benjamin Franklin and a little Smith.' And then we try to figure out what they have in common.

I was kind of shocked at how everyone talks with each other at Commonwealth. In my old school, people just stuck with their own friend groups. I thought it would be like that here—but it turned out to be exactly the opposite. I didn't expect to be able to communicate with seniors and juniors and sophomores at all. I feel really good in small communities. You feel seen.  

Chloe ’27

I get a real burst of energy when I’m able to help students navigate the complexities of the research process. I feel so lucky to have such an incredible patron base of high-level readers and thinkers in our students. 

Jake MacDonnell, Librarian and Registrar

There are all of these resources around us that we can take advantage of.… I like how part of your daily routine is going out into the city and still being with your classmates but in a completely different setting.

Felix ’27

You know, I was hearing about all these other schools, and they definitely had a lot to offer, but Commonwealth spoke more to me because I know they take academics seriously here, but they also care about you as a person and finding yourself.

Happening Now

What happens when you splice an extrovert with a budding neurologist with a writer? You get Can ’29, whose eagerness to share his ideas on life, the universe, and everything keeps him up at night—quite literally. Keep reading to learn more about this first-year student from Boston, including his writing practice (he invokes everyone from Ray Bradbury to Bob Dylan), favorite Turkish foods, research interests (from CRISPR gene therapy to the head injuries depicted in Home Alone), and much more.

Jake-Alexander-hero

Jake has always been a fan of satirical news magazine The Onion, so when he discovered The Leek, Commonwealth’s homage to that publication, as a ninth grader, he was charmed. But in this era of dwindling support for journalism, even student-run comedy newspapers are struggling, and The Leek disappeared for a couple years before Jake stepped in to revive it. But underneath the jokes is Jake’s genuine concern for current events, media polarization, and the imperative to help others. Keep reading to learn more about his work with The Leek and at Commonwealth more broadly, plus his pro tips for making sense of the news when it all starts to sound like satire.

Food for Thought: Commonwealth Students' Most Brain-Bending Paradoxes

Commonwealth students love a good mental exercise, which is why we ask them to share the paradoxes that stretch their minds and challenge their assumptions. Tease your brain with the sampling below and enjoy pondering everything from time travel to extraterrestrial life to Pinocchio…

Vedant-Ramesh-thumb

Vedant has only lived in East Boston since July 2025, but you’d be forgiven for thinking he grew up in the area, given the depth of his community involvement. He has become a vocal advocate for his new neighborhood, as well as the Massachusetts Youth Climate Coalition and other organizations, recruiting several of his fellow Commonwealth students along the way. Here he explains his homegrown commitment to fighting climate change, the “fun kind of suffering” in Geometry Advanced, and the key to getting involved.

Will It Work? Dispatches from Alumni/ae in Public Service

The day of the last conversation for this article marked five days until an odd-year Election Day, thirty days of the soon-to-be longest federal government shutdown in American history, 1,344 days of the Russo-Ukrainian war—and found six Commonwealth alumni/ae with a lot on their minds.

In Government Center, a mile’s walk from his old high school, Matt Costas ’14, Chief of Staff to City Councilor Liz Breadon, kept tabs on grassroots efforts to feed residents in the face of impending cuts to food benefits. At the Massachusetts State House, Senator Will Brownsberger ’74 worked to pass limits on the eviction of federal workers affected by the shutdown. Across the Charles River, Kevin Ballen ’16—current Harvard Law student, former White House staffer—was already anticipating the 2026 midterms. (“Elections are long,” he notes.) In New York, Camille Simoneau ’10 joined a State Department delegation at the United Nations General Assembly; in Michigan, State Senator Erika (Swanson) Geiss ’89 moderated a session of complex procedural discussions as president pro tempore. And overseas, longtime diplomat Peter Galbraith ’69 delivered a speech in Croatia, where he was once ambassador, while observing signs of weakness in American institutions that alarmed him.

It was a turbulent denouement to a year variously described by these six in government and politics as “uncertain,” “a roller coaster,” and “a constant inferno.” But in their careers and study, they had to continue to address what Peter calls the “first question about any proposed policy or law”: “Will it work? If it won’t work, you don’t need to consider whether it is the right thing to do.”

If you’ve been pondering that question around something you care about, you’re at the same starting point as the alumni/ae you’ll meet here: several never thought they’d enter their roles until they ran up against a problem they wanted to tackle. They all attest that one critical step in finding any solution is listening deeply to others’ experiences. Start now by hearing theirs.

At Commonwealth, we’re looking for inquisitive, driven, and creative students from a wide range of backgrounds. We encourage you to visit us, talk with teachers and students, and see if Commonwealth is right for you.
