The Gwinnett County school board Thursday night approved two leadership changes at local schools. The board agreed to move Beaver Ridge Elementary School principal Jose DeJesus to the Berkmar school cluster to run Berkmar Middle School. The board also approved moving Bethesda Elementary School principal Deborah Harris to the South Gwinnett school cluster, where she will lead Grace Snell Middle School. DeJesus came to the school system in 2005 as assistant principal at Berkmar High. Harris joined the system in 1996 as a speech-language pathologist at Rockbridge Elementary.
