Nansemond-Suffolk Academy is looking for its third Upper School head in a little more than two years, according to its regular email newsletter.

Mike King will not be returning to the position for 2014-2015 after leaving “to pursue another professional opportunity.”

Kim Aston, a 1988 graduate, will serve as King’s interim replacement for the upcoming academic year, while also continuing in her role as the Upper School dean of students.

King’s service to NSA was short-lived; he came on board in the role in July 2013, to replace Christopher Cox.

Cox had also left the position after a brief stint. His replacement of Brenda Kincaid, who retired after 33 years with the academy, was announced in March 2012.

Beyond the newsletter, Head of School Debbie Russell declined to comment on the turnover.

Aston, also varsity coach of the girls’ basketball program, started with NSA in 2008 after 12 years as a teacher and coach at Western Branch High School.

“Given Kim’s passion for NSA, proven leadership experience in the Upper School, knowledge of the day-to-day workings of the Upper School, and relationships with both the Upper School faculty and students, Kim will easily transition into this new role,” according to the newsletter.
