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.

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.

Natan-Shapiro-meet-our-students-hero

To be successful, you should feel like you’re failing. At least, that’s what keeps Natan motivated, especially in the history classes he can’t get enough of at Commonwealth. Those history lessons dovetail perfectly with his other great passion: politics. And while national politics might dominate the headlines, Natan knows the real action is local. “There's drama, things are happening, and it's where you can really make a change, especially as a teenager.” Keep reading for his advice for other students hoping to make an impact, plus his recess shoutouts, the key to good grilled cheese, and the Commonwealth club everyone should join…

Meet-Dive-In-students-Violet-hero

Violet will be the first to tell you: Dive In Commonwealth is hard. “It was a bit challenging,” she says, “but the classes pushed me to grow in ways I didn’t think I could. It forced me to think deeper, work harder, and all around just made me a lot more confident in my academic abilities.” Here’s your chance to get the inside scoop about Dive In Commonwealth, as Violet recaps what each summer day entails, as well as what to expect as a student.

faculty-research-how-did-we-get-here

Like Henry David Thoreau wearing down the path around Walden Pond, Melissa Glenn Haber appreciates a good thinking walk—and it took many steps to plan her most recent elective at Commonwealth, U.S. Politics and Policy in the 21st Century. A product of a Hughes/Wharton grant, the class challenges students to examine how we got to this political moment, starting with a philosophical foundation, digging into fifty years of economic and social policies, looking at the impact of COVID and the attention economy, and much more in between. Keep reading to learn more about Ms. Haber’s how and why.

Searching for Truth in the Age of Misinformation

Between debates over bias in mainstream media outlets, the prevalence of inaccurate information online, and the increasing number of bots on social media, Americans’ trust in the information they consume has waned, accelerating a downward trend that has been observed since the 1990s. A Pew Research survey from late 2016 found that one-third of Americans said they often saw false information about politics online, and twenty-three percent said they had, whether knowingly or unknowingly, shared false information online themselves.

Nearly a decade later, we’re no closer to putting a cap on the spread of fake news. While by nature difficult to measure, misinformation (inaccurate information from a mistaken source) and disinformation (inaccurate information deliberately shared with the intent to manipulate) seem increasingly unavoidable, especially on social media. Reporting in October 2025, Gallup found that twenty-eight percent of Americans express trust in mass media, down from forty percent just five years earlier, in 2020.

But who is “the media,” and what has this era of misinformation meant for them? For Commonwealth alumni/ae working in newsrooms, there’s a clear imperative to face the evolving realities of our times head-on—and to carry on delivering good journalism to a public that needs and deserves it.

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.
