Tri Star Med Prep students recently volunteered at Celina Primary Schools’ annual health fair. The Med Prep students manned stations in which they talked to Kindergarten through second grade students about important health topics like first aid, height and weight, and hand washing. According to Med Prep instructor, Brenda Speck, the health fair is a great opportunity to teach her students the importance of community service and to give them practical experience in how to educate others about health issues.
