Julian King has resigned from his position as T.C. Williams boys’ basketball coach after six seasons leading the Titans.

King informed T.C. Williams athletic director Steve Colantuoni of his decision last week, citing a desire to focus on his pursuit of a master’s degree.

“I knew there were some things I needed to take care of personally, like going back to school next year for my master’s,” King said. “I feel like the school and kids need someone who’s going to be in the building, and considering I don’t work at the school, the time I would be devoting to my master’s would make it tough to do that.”

King came to T.C. Williams as an assistant for the 2007-08 season and served on a staff that led the Titans to the Virginia AAA state title that year. When Ivan Thomas resigned as head coach after the season, King was promoted to the position. In six seasons, King led the school to three district titles, two Northern region championships and three state tournament appearances. The team finished 4-16 this winter.

“Being at T.C. was a great learning experience and opportunity opened for me by Ivan Thomas, and I had a great run,” King, 40, said. “This past year wasn’t very great, but you can’t dwell on one year. . . . Hopefully after I get my master’s, my body of work will present an opportunity for me to coach somewhere else.”

Colantuoni said the school plans to begin its search for a new boys’ basketball coach next week.

“Julian’s been very successful here, so it did kind of take me aback when he resigned,” Colantuoni said. “But we’re grateful for all he’s done.”
