Guerin Prep students participate in community service throughout the year. The Sophomore Nolan Scholars chose The Ronald McDonald House as their charity in 2011-12. The students volunteered to serve breakfast there and raised $1,000 through a number of student fundraisers including a Prom Fashion show.
Another service project that the Guerin students participate in is the Teens for Jeans. Through the Key Club, students collected more than 400 pair of jeans for the program which donates the jeans to needy and homeless families in the area.
