New Faces at Commonwealth

Was it Heraclitus who said, “Change is the only constant in life”? 

This grain of wisdom rings especially true as we start a new school year following eighteen months of seemingly constant change from in-person to virtual to hybrid to in-person learning again. Not only that, but Commonwealth School is thrilled to welcome a cadre of faculty and staff members for the 2021–2022 academic year. As you might’ve heard, they include Jennifer Borman ’81, our new Head of School, and Lisa Palmero McGrath, our new Director of Diversity, Equity, and Inclusion. 

Joining these equally passionate and compassionate school leaders is a host of new faculty and staff who will soon add to the chorus of learning and buzz of excitement in our little school. And so, without further ado, meet the new faces of Commonwealth.

Bronwen Callahan, History Teacher

A sabbatical replacement for Ms. Grant, Ms. Callahan earned a B.A. from the Gallatin School of Individualized Study at New York University where she concentrated in Middle Eastern Studies and Arabic. She then spent three years as a Peace Corps Volunteer in both Jordan and Georgia, where she taught English to K-12 students. In 2019, she obtained her master’s in Theological Studies at Harvard Divinity School with a focus on Islamic Studies. From 2019 to 2021, she taught Ancient and Modern History at King’s Academy in Madaba, Jordan.  

Dethie Faye, Chef Manager

Chef Faye joined Commonwealth as Chef Manager via Flik Dining Services in June of 2021. He received an A.S. in Culinary Arts and a B.S. in Food Service Management from Johnson & Wales University in Rhode Island. As a student he turned an internship at a Maine restaurant into four consecutive seasons in the kitchen, eventually becoming sous chef in the process. After that, Chef Faye moved back to his home state of Pennsylvania to pursue fine dining at one of Philadelphia’s top restaurants. He later made his way up to Boston, joining the management team for British Airways International Lounge at Logan Airport before joining Flik and coming to Commonwealth. In his free time, he is always cooking, especially making pasta—trying different shapes and introducing new fillings. He also enjoys basketball, art, fashion, and travel. 

Adam Hinterlang, Director of Information Technology and Facilities

Mr. Hinterlang comes to Commonwealth after working in a wide variety of IT and facility positions that range from an Emmy Award–winning motion graphics and design company to interactive event management at auto conventions across the country. Adam received an MFA in Electronic Integrated Arts from Alfred University in 2006 and a BFA from the Kansas City Art Institute, where he double-majored in Photography and New Media, and Art History. In his spare time, you can find him in his studio working on his drawing and animation practice, playing guitar and bass, collecting vinyl records, or making hot sauce. Most of all, he loves spending time with his wife, ceramics teacher, Kyla Toomey; their son, Harry; and their bad dogs, Ruby and Kilgore.

Abby Lawrence, Advancement Coordinator

Ms. Lawrence earned her B.A. in English and Educational Studies at Macalester College in Saint Paul, Minnesota, where she specialized in Creative Writing. Abby is a triplet whose birthday lands on Halloween! During her free time, she enjoys cycling on the Minuteman Bikeway, indoor rock climbing, and doing all things crafty.

Jake MacDonnell, Librarian and Registrar

Mr. MacDonnell earned his B.A. in English literature from Oberlin College, and his M.S. in Library Science with a concentration in archives and records management from the University of North Carolina at Chapel Hill. He has worked in academic, governmental, and school library settings. Outside of work, he enjoys reading books, playing pickup basketball, watching movies, and seeing live music.

Lisa Palmero McGrath, Director of Diversity, Equity, and Inclusion

Ms. McGrath (she/her), a Filipino American who was born and raised in Saudi Arabia, has worked at New England independent schools since graduating from college. Beginning her career as a student activities director and middle school humanities teacher, she discovered that—by supporting DEI programs at her school and in region—she could help build the kind of compassionate, inclusive communities she remembered from her expatriate childhood. Ms. McGrath earned her B.A. in Sociology from Ithaca College, M.A. in English for Teachers from Western New England University, and M.A. in Psychology in Education from Columbia University. She lives in Charlestown with her partner, who was also her prom date; their son, Andrew; and their 14-year-old rescue, Snowflake.
