April 19, 2019

     During its monthly meeting in April, the Gwinnett County Board of Education approved three principal appointments for the 2019-2020 school year. Cortina Harris, an assistant principal at Lovin Elementary School, will become the principal of Alcova Elementary School. She will fill the position currently held by Dr. Todd Langley who has accepted a district level position in another school system. Jonathan Day, principal of Mulberry Elementary, is transitioning to the principal post at Harmony Elementary. He will succeed Principal Anne Marie Keskonis who is retiring at the end of the school year. Niki Ross, an assistant principal at Phoenix High School, will become the next principal of that school as Principal Donna Scott retires. In other personnel action, the Board named South Gwinnett High School Principal Monique Lee as Assistant Director of Positive Behavioral Interventions and Supports. With the approval of these appointments, the district will soon begin its process to identify new principals for Mulberry Elementary and South Gwinnett High School.
