Meet Faculty and Students
I've never seen a school like it before, from the building to the close-knit community. I look forward to going to school everyday, as I never know what will happen next.

It is humbling and exhilarating to come to work every day to a place where people are working for a common goal with such a mix of competence and humanity.
César Pérez, History and Languages Teacher
I was first interested in Commonwealth by the small class sizes and the very rigorous environment. Visiting and having a virtual class was what drew me in. I'm very happy about making the choice to come here. The classes are intriguing, to say the least. There is difficulty but nothing I can’t handle. And the opportunities, such as Project Week, are unique, and they allow us to develop our own interests.

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.
Melissa Glenn Haber ’87, History Teacher
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
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
“‘It’s always about noticing,’” Natalie Mills ’13 recalls Commonwealth art history teacher Judith Siporin telling her students. “‘What do you notice? What do you see?’”
Natalie fell in love with noticing at a young age, entranced by trips to art museums with her parents. After taking two impactful art history classes at Commonwealth, her passion for the subject and determination to pursue it further solidified. But the journey wasn’t quite how she pictured it...
These days, Joe Reid ’75 begins his mornings practicing Chopin or Mozart, warming up for the day before heading to a gig, helping students perfect their technique, or some of both. But forty years ago, Joe couldn’t imagine his love of music paying the bills.
Commonwealth has always had a reputation for athletics: specifically, that we’re not very good at them. There was something charmingly countercultural about embracing that identity, as many students and alumni/ae have. We’re nerds! We have our Plato and our problem sets. Let the other schools have their sports, and let our (nonexistent) football team remain undefeated. The joke in the 1980s: “Why did the Commonwealth student cross the road? For sports credit!” (Though that’s an unfair characterization; the ’70s and ’80s had solid fencing and squash programs, and a strong dance program under Jackie Curry.)
That reputation has held fast, even though the school has required athletic participation for more than forty years for all the reasons one would expect: camaraderie, leadership opportunities, general health and fitness, etc. Then, in yet another COVID-19 pandemic shift, Commonwealth saw not just an influx in applicants but a hunger amongst students (and families) for connection, including on the courts and fields.
Enter Jackson Elliott ’10, who returned to Commonwealth as our Director of Athletics and Wellness in January of 2022, bringing with him not just passion for sports and a deep familiarity with the school but a commitment to harnessing our recent growth to shape an athletics program that both speaks to student interests and stays true to our ethos. Jackson now coaches students as they face off against the same schools he played as a student athlete, amongst a host of other responsibilities. Keep reading as he and Head of School Jennifer Borman ’81 reflect on the evolution of Commonwealth athletics and moving toward their shared goal.
Long-timers at Commonwealth eventually lose track of how many hats they’ve worn. Some of Don Conolly’s: teaching Ancient History, coordinating academic support, serving on the admissions committee, leading trips to Rome and Naples, and teaching electives on philosophy, Greek tragedy, art history, Russian literature, and precolonial Mesoamerican cultures. This fall, he embarked on his second year of teaching English 9 and spearheaded the new “Classics of World Cinema” discussion group, launched with the screening of a short film by the Soviet director Andrei Tarkovsky at Hancock. The next night, the talent show opened with the Beatles’ “Good Day Sunshine,” arranged by Don for an enthusiastic faculty band. His fellow long-timers are used to seeing him pivot from loading speakers and keyboards into the equipment van to paraphrasing Tarkovsky’s idea of the purpose of art: “to plough and harrow the soul, rendering it capable of turning to good.
Students commute to Commonwealth from more than forty cities and towns, drawn to our academic environment, of course, but also empowered by our central location in one of America’s greatest cities: Boston. Aside from its historical significance and charm, Boston is a hub for scientific research, academia, the arts, and so much more—and Commonwealth students take advantage of it all. Keep reading to hear students’ perspective on learning in Boston from our cozy home in the heart of Back Bay.
