Mark A. Devey, Head of School
Born in Pittsburgh, PA, and raised in Bethlehem, PA, Mark A. Devey grew up on the campus of Moravian Academy with his father at the helm as headmaster. At the University of North Carolina, Chapel Hill, he earned a BA in English and went on to earn a master’s degree in Educational Leadership from Columbia University’s Klingenstein Center Teachers College, with a concentration in Private School Leadership.
Mr. Devey began his teaching career at Fessenden School in Massachusetts, where he also served as coach, theater director, and dorm parent. Subsequently, he has worked as an Assistant Academic Dean of Students at Harvard-Westlake School in California, Middle School Head at The Kinkaid School in Texas, Head of Middle School at The Episcopal Academy in Pennsylvania, and Head of School at Indian Mountain School in Connecticut.
At Indian Mountain School he oversaw the planning and building of a new dormitory and new student center that became the hub of the campus and integrated art, music, and all academic disciplines with the cutting-edge Fabrication Laboratory as a focal point. Under his leadership, the school revamped its academic programs, expanding the STEAM program (Science, Technology, Engineering, Arts, Math) to include robotics, rocketry, a SeaPerch underwater robotics program, and a variety of opportunities that resulted in multiple students earning top achievement awards at the Connecticut State Invention Convention.
He has swiftly molded his legacy at Perkiomen School since arriving in 2015. Mr. Devey’s creation of the Entrepreneur Institute, fueled by a multi-million-dollar campaign to fund Perkiomen’s state-of-the-art Innovation Center, redefined the school’s education model. This trend of innovative learning strengthened further when the School launched the Medical Institute in 2018, followed by the Artificial Intelligence Institute in 2019, and the Design Institute in 2022.
In the fall of 2025, the Helen and DeLight Breidegam Jr. Student Center officially opened, the culmination of Devey’s vision to build a student-focused hub, establishing it as the symbolic heart of the Perkiomen community, and anchoring it as the physical heart of the campus. Perkiomen’s longstanding social hangout, café, and bookstore, Roberts Hall, known to the community as “Robbie’s,” was added in 1958, a time where Perkiomen served a population of less than 150 boys. More than 65 years later, it was time for this well-used space to accommodate the needs of today’s student body. The Breidegam Student Center is a space more technologically attuned, more dynamic, and can accommodate a population now more than twice as large as Robbie’s intended to serve. The project was funded through the Our Moment to Lead Campaign, a six-year, $45 million capital campaign that was the largest in school history.
While Mr. Devey consistently worked to expand and elevate academics and the arts, he also built and strengthened a highly successful athletics program as an essential part of a comprehensive school experience. Despite Perkiomen’s relatively small size, the school captured multiple state championships and helped develop dozens of elite student-athletes, some of whom went on to become college All-Americans and professional athletes. Yet for Mr. Devey, athletic success is never measured solely by championships or individual accomplishments. He believes that athletics should complement the broader educational experience — developing discipline, resilience, teamwork, and character —while ensuring that student-athletes remained fully engaged in the intellectual, artistic, and community life of the school.
In addition to implementing strategic initiatives, he prioritizes daily contact with students. The Head of School can be found coaching soccer, singing with the band, cooking in the teaching kitchen, or brainstorming with students about future campus projects.
With Mr. Devey’s vision for dynamic, authentic learning, Perkiomen School seeks to reimagine traditional education by emphasizing creative thinking and problem solving. By providing students with a toolkit of applicable skills they are enabled to excel at the university level and succeed as professionals in an ever-changing world.
