Telia Marks-McCall

GILL — Telia Marks-McCall will join Northfield Mount Hermon’s leadership team as director of Athletics, effective July 1.

Marks-McCall will lead NMH’s highly competitive athletics program, comprising 33 sports and almost 70 teams. She will provide strategic vision and day-to-day leadership for all aspects of the program, which promotes physical well-being and competitive integrity while staying true to the school’s educational mission, values, and commitment to developing citizens and scholars.

“We’re thrilled to welcome Telia to the NMH community in this important role,” Head of School Brian Hargrove said. “NMH’s athletics program is an integral part of our school community, with teams for students of all levels, comprehensive PE and wellness programs, and high-caliber facilities. Our coaches are deeply engaged in all aspects of student life, serving as role models, advisors, and mentors to their players and non-athletes alike. Telia’s background and experience leaves her well-prepared to lead our work shaping and supporting our citizen-scholar-athletes.”
Marks-McCall brings a strong track record in athletics leadership, promoting positive cultures grounded in character, integrity, and a strong work ethic. She comes to NMH from Maryvale Preparatory School, where she’s served as director of Athletics and head girls’ basketball coach, overseeing six championship titles and three runner-up finishes across athletic programs while supporting nationally ranked teams in soccer and lacrosse.

Her previous positions include director of Athletics and Auxiliary Programs and head basketball coach at Miss Hall’s School, where she led the development of a comprehensive strategic plan for the program. She also brings athletics administrative experience at the collegiate level, at Quinnipiac University and the University of Iowa.

Marks-McCall holds a bachelor’s degree in sociology from the University of Virginia and a master’s degree in organizational leadership from Quinnipiac. At Virginia, she was the basketball team’s Rookie of the Year. After college, she spent two years playing professionally in Luxembourg and Finland, which helped her bring a global perspective to her approach to athletics and leadership.

“I am honored to join the Northfield Mount Hermon community as director of athletics,” she said. “I look forward to building on its tradition of excellence by fostering a competitive, values-driven program that brings out the best in every student-athlete.”

GILL — David Biancamano will join the senior leadership team at Northfield Mount Hermon (NMH) as chief advancement officer beginning May 1.

Biancamano will lead the school’s advancement and marketing and communications teams, shaping its vision for fundraising and engagement and building the infrastructure and culture necessary to achieve its priorities and fulfill its aspirations for its future. He will serve as a strategic partner to the head of school and the NMH board of trustees, guiding the design and execution of advancement goals that support the school’s mission, strategic plan, and financial sustainability.

“NMH benefits from a proud tradition of alumni, family, and broader community engagement. Current students and employees benefit from this dedication, advocacy, and generosity in profound ways,” Head of School Brian Hargrove said. “Finding the right person to lead our team to honor this commitment and deepen this connection further in the years to come is incredibly important.

“We conducted a national search that attracted a rich pool of candidates. I am thrilled that, in our own backyard, we found Dave,” Hargrove continued. “His record of success in leading diverse teams, bridging volunteer and donor interests with institutional priorities, and shining the light on the power of education as a societal force for good distinguished him throughout the process.”

Biancamano brings to the role nearly 25 years of educational experience, including leading comprehensive fundraising programs and developing campaign strategy, major and principal gift programs, and donor engagement models that strengthen institutional culture and long-term sustainability.

He comes to NMH from the UMass Amherst Foundation, where he serves as an assistant vice president, overseeing fundraising and advancement efforts for a diverse portfolio of university colleges and schools. His previous roles include deputy athletic director for development at UMass Amherst, senior associate athletic director at James Madison University, and director of development for athletics at Rice University. He received his bachelor’s degree in communication from Central Connecticut State University and his master’s degree in sports administration from the University of Miami.

“I am grateful to the Northfield Mount Hermon board of trustees and to Brian Hargrove for the opportunity to join this extraordinary school at such an important moment,” Biancamano said. “Throughout the search process, I was inspired by the clarity of NMH’s mission, the strength of its leadership, and the deep commitment of its community. I am excited to partner with the advancement team and colleagues across the school as we build on the strong momentum. At its core, advancement work connects generosity to impact, and I look forward to ensuring that our efforts continue to strengthen NMH’s mission.”

Biancamano will assume the chief advancement officer position from Trish Jackson, who will retire on June 30 after serving in the role since 2022. Jackson led the successful $275 million “This Place, This Moment: the Campaign for Northfield Mount Hermon,” positioning the school for long-term sustainability and growth as it approaches its 150th anniversary in 2029 and beyond.

“It is hard to overstate Trish’s contributions to NMH as our advancement leader,” Hargrove said. “She stepped in to lead our team on the eve of our campaign launch. It was a daunting challenge and one that she was uniquely suited to navigate and, in fact, master. Her vast experience as an advancement leader, her gifts as a relationship and volunteer manager, and her devotion to centering our mission in all that we do resulted in a smooth transition and, of even more note, success in elevating the program to new heights.

“Trish is a force for good, and I deeply appreciate her commitment to NMH, her service as an educational leader more broadly, and her ability to call us all to the best versions of ourselves,” he added.

Biancamano’s May 1 start will allow his tenure to overlap with Jackson’s, ensuring a successful transition of leadership as NMH wraps up “This Place, This Moment” at the end of the fiscal year.

Stacey Johnson

GILL — Northfield Mount Hermon (NMH) announced that, effective July 1, Stacey Johnson will join the school’s senior leadership team as chief financial and operations officer, a role central to advancing NMH’s strategic priorities and strengthening the operational foundation that supports student life.

Known for aligning financial strategy with mission-driven growth, Johnson has led complex institutions through periods of transformation, modernization, and strategic investment while overseeing up to $500 million in financial resources. She comes to NMH from the Kennedy Center for the Performing Arts, where she served as chief financial officer from 2022 to the spring of 2025. At the Kennedy Center, she directed all finance, accounting, planning, and federal contracting functions.

Prior to that, she was chief financial officer of the American Federation of Teachers, a national labor union, where she developed new, modernized systems and executed strategies to help AFT grow its reserves tenfold during her tenure. She also served as chief financial officer for Alexandria City Public Schools in Virginia, where she garnered the confidence and trust of the School Board, City Council, and broader community, receiving nationally recognized awards from the Assoc. of School Business Officials and the Government Finance Officers Assoc.

As NMH’s chief financial and operations officer, Johnson will provide leadership, oversight, and stewardship for all aspects of the school’s financial resources and physical assets, ensure institutional integrity on fiscal matters, and promote best practices in finance and administration. She will partner with others on the senior leadership team to ensure that approved strategic initiatives are appropriately funded and will serve as staff liaison to the NMH board of trustees’ finance; investment; buildings and grounds; and audit, risk, and compliance committees.

“We met with candidates from around the country, and Stacey distinguished herself as a leader with a deep sense of purpose, a passion for our mission, and a demonstrated ability to apply her considerable experiences and judgment to advance the organizations where she has led,” NMH Head of School Brian Hargrove said.

Monie Hardwick, chair of the NMH board of trustees, added that “Stacey has a long-standing commitment to education and nonprofits. The trustees are confident that she will build on the momentum of the current campaign, continuing to ensure Northfield Mount Hermon is on the strongest possible foundation for the future.”

Early in her career, Johnson also held finance positions at Conservation International, the National Academies, and the Urban Institute. She received a bachelor’s degree in business administration from the University of Miami and an MBA from George Washington University.

She joins NMH upon the retirement of Mary McEneany, assistant head of school for finance and operations and chief operating officer since 2019. In the last seven years, NMH’s endowment has doubled to more than $280 million, capital project investments have exceeded $75 million, and the school has increased annual financial aid allocations by 55%. In addition, faculty compensation and employment retirement contributions have increased by 33%.

GILL — Northfield Mount Hermon has received its largest-ever gift and one of the largest donations ever to an independent school. The $50 million bequest from the late John Mitchell, who graduated in 1956, will endow need-based scholarships and expand support for faculty, key objectives of the school’s $275 million fundraising campaign.

Announcing the gift to the NMH community, Head of School Brian Hargrove and Monie Hardwick, NMH board chair, described it as “an act of generosity from an exceptionally accomplished alumnus who was modest in his profile but profound in his gratitude for the education he received.”

John Mitchell arrived at the Mount Hermon School for Boys in 1952 as a scholarship student from an unheated home in a small town in Eastern Mass. Recognized early as academically gifted, Mitchell participated in several sports and thrived in his NMH courses, graduating as class valedictorian. Following NMH, he earned degrees from Yale and NYU and went on to a long and distinguished career as president of Global Manufacturing at Pfizer.

“John credited his time at NMH as a turning point in his life and held tight to the habits and values nurtured at NMH: hard work, critical thinking, lifelong learning, and service,” Hargrove and Hardwick said.

Mitchell later served on the NMH board of trustees, where he brought a particular focus on finances and campus planning. With characteristic pragmatism and modesty, he made numerous gifts to top off the budget for faculty housing projects, athletics facilities, the early-childhood center, and related campus improvements.
