Tri Star’s Dennings Building juniors and seniors volunteered with the Mercer County Angel Tree on Thursday, as part of a community service project for their SkillsUSA student organization. Welding, Med Prep, Precision Machining, Engineering Technology, and REC Tech students helped set-up, unload, and sort truckloads of donations to be given away. Prior to Thursday’s work, these Tri Star classes collectively raised $2790 and then went shopping to purchase clothing and toys so they could sponsor 147 Angel Tree children. Tri Star students were among a number of volunteers who worked to prepare for the annual event that helps Mercer County families.
