Science Center Taking Shape at St. Marks

Construction is progressing on the new Winn Science Center and McDermott-Green Science Building on the campus of St. Mark’s School of Texas, with the outside of the building nearing completion and indoor facilities underway.

Countertops, sinks, cabinets, lab tables, and more are being installed in the classrooms and science labs as the state-of-the-art facility eyes its’ 2019-2020 grand opening.

“The new building will put even more of science education in the hands of the students,” said Fletter Carron, the Stephen M. Seay ’68 science department chair at St. Mark’s. “There will be more and better outlets for their creativity and more opportunities to explore their curiosity.”

The center will include a planetarium, a science lecture hall, greenhouse, robot lab, biotechnology lab, a classroom for lower-school science activities, an atrium, and outdoor learning center.

The McDermott-Green Science Quadrangle has long been a staple at St. Mark’s, but the Winn Family Foundation donated $10 million in 2014 for a larger, more advanced science center. Over the next three years, another $32 million was given by 55 families, and the Board of Trustees approved construction of the center.

Groundbreaking took place in 2017.

“St. Mark’s is an incubator that turns a boy’s dreams into the accomplishments and character of a man,” Steve Winn said. “We want to continue what Eugene McDermott and Cecil Green started nearly 60 years ago.”
