Students, faculty and staff at McClure Health Science High School will be greeted by a muscular mannequin named “Duke” when they enter the school’s front doors Aug. 5.

The brand new 303,690-square-foot high school is the second of three new high schools Gwinnett County Public schools projects to open by 2022 — Paul Duke STEM High School opened last year and Seckinger High School will mark the final phase.
