The 2019-2020 academic year brought many challenges to the St. Mark’s community. First, a damaging tornado and then a disruptive pandemic. Through it all, our Marksmen and their teachers endured, supported by our alumni community along the way. Guided by the strategic initiatives laid out in Goals for St. Mark’s IV, the St. Mark’s community finished a renovation to the McDermott-Green Science Building, continued to invest in Character and Leadership education, rolled out new health and wellness initiatives, and unveiled a new daily schedule for 2020-2021. In the classrooms, fine arts studios, and on the playing fields, Marksmen reached tremendous heights, always representing with courage and honor.


On the evening of Sunday, October 20, 2019, an EF-3 tornado touched down in the Preston-Royal neighborhood, striking a direct hit to the St. Mark’s campus. Winds up to 165 miles per hour blew down the east and west walls of Hicks Gym, damaged the roofs of several buildings, and sent debris flying across campus. As the sun rose on Monday morning, crews quickly assessed the damage and began to clear debris. While School was closed for the week, the community quickly rallied together to support one another. Hockaday and Greenhill hosted St. Mark’s Homecoming games and festivities on the Friday after the tornado, as originally scheduled. The Drama Department relocated its fall play 1776 to Northpark Presbyterian Church, where they performed three sold-out shows. With Hicks Gym destroyed, St. Mark’s renovated Spencer Gymnasium into a regulation basketball court in time for the winter season. 

St. Mark’s will continue grappling with the tornado’s many impacts for years to come. Repairs and construction will be ongoing as the School seeks to provide students the best possible facilities in which to thrive. But the October 2019 tornado made one thing very clear: The St. Mark’s community is stronger than ever.

Days before the start of the 2019–2020 school year, St. Mark’s celebrated the culmination of the Science Center Project and more than five years of planning and construction. On August 21, 2019, members of the community, including donors, Trustees, parents, alumni, faculty, and staff gathered for a ceremony to rededicate the completely renovated McDermott-Green Science Building. Mary McDermott Cook, the daughter of Margaret and Eugene McDermott, joined Melinda and Steve Winn ’64, Eugene McDermott Headmaster David Dini, Board of Trustees President Clark Hunt ’83, Vice President Kathy Crow, and Stephen M. Seay ’68 Science Department Chair Fletcher Carron, in cutting the ribbon from the Winn Science Center into the McDermott-Green Science Building. The two buildings are now joined through a two-story glass connector, uniting 75,000 square feet of science education facilities.

Goals for St. Mark’s IV challenged St. Mark’s to “explore, design, and implement a daily schedule that better addresses the evolving needs of students and faculty.” In response, a Schedule Review Committee, comprised of administrators, department chairs, and faculty members, has worked tirelessly over the past several years, exploring ways to allocate time for realizing strategic priorities.

In an effort to build on the School’s longstanding sense of community during this remote learning, St. Mark’s recently launched 10600, a new webpage that featured engaging content from teachers and students. Community members submitted videos and photos, sharing how they learned and stayed active during this time of social distancing.


On what would have been their last day of school, the Class of 2020 visited campus for the first time in two months for a Blue Shirt Parade. As faculty and staff cheered on from a safe distance, the boys received a copy of the 2020 Marksmen yearbook and handed over their blue senior shirts to be draped on the Perot Quadrangle sign.


Although the spring seasons were shortened due to COVID-19, 2019-2020 proved fruitful for Lions athletes. To celebrate the hard work, dedication, and achievements of our student-athletes, a virtual Athletic Banquet was launched and included Major Awards, Team MVPs, and a video retrospective.
