Become a Big

We’re so thrilled you’re interested in becoming a mentor ("Big") with Big Brothers Big Sisters of FSW. As the country’s largest mentoring program, you can feel confident that by volunteering, you will make a significant and very real impact on a child’s life. We ask that, once paired, you arrange time to meet with your mentee ("Little") just four hours a month. Depending on the Big Brothers Big Sisters program you’re in, you will meet at your Little’s school, at your workplace or in the community. We match volunteers over the age of 21 with children between 7-17 years old in Westchester County. We are especially in need of male volunteers to match with our large wait list of male mentees.

Being a Big Brother or Big Sister is incredibly fulfilling and fun, so please don’t hesitate to reach out with any questions by contacting us at 914-937-3779 or review our frequently asked questions section on being a volunteer mentor.

Suggested Activities

Your Little can join you for the kinds of activities you already like to do – shoot some hoops, play a board game, go to the movies, share a pizza, take a walk in the park, or just hang out together and talk.
