Our Mission

Mission Statement: In our club, we will strive to serve our community of Orange County. We will do this by volunteering our time to the Orange County Food Bank. Through volunteering, you can learn new skills, take on a challenge, be a part of a community, meet new people, and most importantly have fun!

Description: Once a month, we will go as a group to volunteer at the O.C. Food Bank (usually on Saturdays) and we will be a part of their assembly line of volunteers. The boxes that will be made will go to low-income senior citizens. We will also meet once a month, during the Advisory Period.

Co-Presidents: Michelle Chaput '25
