Join us for the BIG Brunch 2025, an opportunity to learn more about what we do at Big Brothers Big Sisters of Flagstaff and how you can help support the one-to-one mentoring provided in our community.  This event is free to attend and we encourage both long-time supporters and prospective donors to come and learn about how BBBSF makes an impact.  This year the BIG Brunch is being held in memory of Marlene DeRosa, a long-time supporter of BBBSF.  

 

The BIG Brunch is Big Brothers Big Sisters of Flagstaff's most significant fundraising event. Contributions received allow for continuation and growth of one-to-one mentorship match pairings of Bigs and Littles in our community.

BBBS mentorship has positive outcomes in educational, social, and economic areas.
