SALISBURY — One of Knox Middle School’s co-principals has resigned, the Rowan-Salisbury School System announced in an e-mailed press release.

Dr. Latoya Dixon resigned effective Tuesday. Dixon and co-principal Dr. Mike Waiksnis were hired in June 2014 as the system’s first tag-team administrators in the hopes that the two would revitalize Knox Middle School.

During her time with the school system, Dixon was named Principal of the Year in August and worked with Waiksnis to transform Knox from a struggling middle school into a magnet program. The program, the Knox Center for Accelerated Studies, begins in August.

Until Dixon and Waiksnis, Knox went through five principals in four years, Superintendent Dr. Lynn Moody said.

The two had overlapping contracts with the school system, the city of Salisbury and Catawba College as part of a local incentive to attract and retain principals at Knox. In addition to their salary from Rowan-Salisbury School System, the two received a pay supplement from the city of Salisbury and taught in Catawba College’s master of education program.

Moody said she’s glad that Knox had the same administrators for two years.

“I hate to see her leave. … It’s a big loss to our school district,” she said.

But Waiksnis is staying at Knox, Moody added, saying she hoped it would bring some continuity to the school.

According to the press release, Chris McNeil has been named interim administrator at Knox, and Moody said the system plans to advertise for a “deputy principal,” who will learn from Waiksnis and help with the running of the school.

“Dr. Moody is working Dr. Waiksnis and administrators on the next steps to be recommended to the Board of Education,” the release reads.

Dixon will become the director of the Office of School Transformation at the S.C. Department of Education.
