Eric Williams will take over as superintendent July 1. (Noah Stephens)

Next week marks the end of a more than two-decade run at the helm of the Loudoun County Schools for Edgar B. Hatrick III.

The longest-serving schools chief in the region will retire June 30. Eric Williams, a relative unknown to county residents, will take charge. Williams has been the superintendent of York County schools in Virginia since 2008. He’s also a former high school history teacher in Fairfax.

By way of introduction, the incoming schools chief offered parents some biographical tidbits about himself during a recent visit to Loudoun.

Here are some highlights — nine things you may not have known about Eric Williams, courtesy of Loudoun schools spokesman Wayde Byard.

1. Williams is one of seven children of an Air Force colonel.

2. When his father was stationed in the Washington area, he became a lifelong Redskins fan.

3. He met his wife, Michelle, when they were students at William & Mary.

4. Michelle Williams is a middle school Spanish teacher. The couple taught together in Sao Paulo, Brazil.

5. President George H.W. Bush once spoke to Williams’s government class at James Madison High School in Vienna. (The father of one Williams’s students worked in the White House.) “We had no advance warning that he was going to come speak to our students,” Williams told parents during a meeting with the Loudoun Education Alliance of Parents. “The Secret Service showed up and told the principal.”

6. Williams’s daughter, Lexi, just completed her sophomore year of college and is a Division III soccer player.

7. His son, Bryce, is entering his senior year of high school and is part of a state championship relay team in track. (Williams also is an avid runner.)

8. Williams has coached his children’s soccer teams since they were 3 years old and even coached a travel team while superintendent.

9. He opened a high school as an assistant principal with 1,400 students, with that number growing to more than 3,000 by the time Williams became principal.

“I’m empathetic or understanding of the growth that we face here in Loudoun,” he told parents.
