About BIG BROTHERS BIG SISTERS HAWAII INC

Big Brothers Big Sisters Hawaii, Inc. is a Honolulu-based 501(c)(3) youth mentoring organization that supports keiki (children) across the Hawaiian Islands through professionally supported one-to-one mentoring relationships. The organization operates community-based and school-based mentoring programs that serve children aged 6 and up, guiding matches with trained volunteer mentors and providing enrollment, monitoring, and family support. In recent years BBBS Hawaii expanded its statewide reach through strategic partnerships and organizational consolidation, offering programming free to families and working with schools, community partners, and volunteers across multiple counties. The organization has reported program-level impacts (including hundreds of youth served, routine family outreach and match support, and scholarship awards) and has launched recruitment campaigns such as the ALOHA 100 / 100 Men in 100 Days initiative to address mentor shortages for boys and other youth in need.
