Calvert School’s Board of Trustees is responsible for the strategic vision and direction of the School. Currently, the Board is comprised of 19 elected members and Head Master Andrew Holmgren, who serves as an ex-officio, non-voting member. Ward Classen ’71 leads the Board and is the 21st Chairman of the School. By charter, the Trustees serve as a resource for the growth of our School and provide guidance and oversight of operations, endowment, expenditures, and all properties of Calvert. The Board establishes broad policy goals and supports long-range planning to ensure Calvert’s legacy.
Calvert School is proud to welcome three new members of the Board of Trustees. Chosen for their knowledge, passion for education, and expertise,Dave Bramble, Wendy Griswold, and Andrew Schapiro’95 will bring a wealth of knowledge to the School.
P. David Bramble dedicates his time to sourcing transactions, financial structuring, and overseeing project underwriting and execution. A corporate and real estate attorney by training, David brings a deep knowledge of all aspects of the real estate cycle.
Prior to MCB, David served as the Director of commercial lending for a regionally based full-service lending firm, which he co-founded in 2000. Prior to devoting all his time to commercial real estate investment, David practiced law in the transactions group of a D.C.-based international law firm, where he provided corporate and real estate advisory services.
His practice focused on complex workouts, primarily in the real estate and financial products space. David currently serves on the advisory board to the Brown School of Business and Leadership at Stevenson University and the Foundation Board of the Mt. Washington Pediatric Hospital.
David has also served on the Board of Directors of a federally chartered bank, served as a Commissioner on the Maryland racing commission as well as on the Boards of multiple real estate and non-real estate related charitable organizations. David received his J.D. from the University of Pennsylvania, and an A.B. from Princeton University.
Andrew believes that great storytelling, design, and experiences can create moments of delight while developing deep, meaningful relationships between people and the world around them. He has sought out purpose-driven work throughout his career and has built brands, teams, and products across industries.
Andrew recently joined Calm as the company’s first Executive Creative Director. He is responsible for the expression of the mindfulness platform's brand across all touchpoints. Prior to Calm, Andrew spent seven years at Airbnb, where he started and grew a brand creative team; led an award-winning rebranding; and helped launch and steward the company's mission and core values. During his time with Airbnb, Andrew helped get significant initiatives off the ground, such as the company's Experiences vertical, an e-commerce platform for hosts, and an unlikely format in the tech industry: a print magazine.
Education is an important cause to Andrew. He volunteered time over the course of a year to rebrand Malala Fund with Malala Yousafzai, her father, and their team. He serves on the Board of Directors of Vida Verde, a Northern California nonprofit working to promote educational equity in the outdoors. In addition to joining Calvert's Board of Trustees, he has also served on Calvert’s Alumni Board since 2018.
Andrew lives in San Francisco with his partner and their dog, a retriever whose name, Alta, comes from his favorite ski mountain.
Wendy Griswold has been both a longtime volunteer and leader across Baltimore’s philanthropic sector. She has served on the board for several local organizations, including the Maryland Institute of Art, and she served as board president at Ladew Gardens, where she remains a current trustee.
Wendy lives in Glyndon with her husband, Ben, who is a member of Calvert’s class of 1952. Her family has long had a strong connection to Calvert. Wendy has four sons, Laurence Constable '85, James Constable ’79, Charles Constable ’82, and William Whitridge, Jr. ’90. Her two grandchildren, George ’18 and Octavia ’21 continue to keep her active at the School.
Wendy and Ben are leading Calvert 125, a fundraising campaign in honor of the School’s 125th-anniversary celebration. They have long prioritized Calvert in their charitable giving, loyally supporting the Calvert Fund and athletics.
