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.
"The coming days, weeks, and months will certainly be challenging as we work together to get back to full strength, but we are blessed to be in such a strong community that sticks together in good times and bad," said Eugene McDermott Headmaster David Dini. "In recent days there has been an outpouring of generous support from across the area and around the country. From alumni, parents, and friends of the School to our ISAS colleagues across North Texas and beyond, we’ve been blessed by kindness, compassion, and thoughtfulness. We are incredibly fortunate."
