Before the school year officially kicked off, the Lynbrook High School Key Club already received recognition for their hard work volunteering for a good cause.

Lynbrook High School Key Club members were given the opportunity to volunteer at the 10th annual Rose Brucia Golf Outing at the Stonebridge Country Club in Smithtown on Aug. 21. Upon students’ arrival, they were greeted by members of the Rose Brucia Educational Foundation, which works to reduce child abductions. Students and fellow golfers were treated to a barbeque lunch before heading to the course on golf carts. Students worked in pairs on different areas of the course, where they handed out refreshments and supervised to ensure the event rolled on smoothly.

After the game, Key Club members enjoyed dinner during an awards ceremony, during which they received a standing ovation for their dedication and service. The Key Club was also presented with a plaque. Helping hands were still used to hand out raffle tickets and prizes, before students concluded the night by enjoying scoops from the ice cream bar.

The Class of 2027 took their first steps as freshmen at Lynbrook High School during their orientation on Aug. 30 and 31.

The high school’s newest class packed the bleachers in the gymnasium to hear from Principal Matthew Sarosy, assistant principals Salvatore Brescia and Bryan Garcia, and fellow building administrators who reviewed the basics. With their new schedules in hand and with guidance from volunteer seniors, freshmen toured the building, taking note of important offices and classrooms. On the second day, students followed a shortened version of their classroom schedule to help them be fully acclimated once school begins on Sept. 7.
