Become A Big! 

Being a Big Brother or Big Sister is one of the most enjoyable and fulfilling things you'll ever do. You have the opportunity to help shape a child's future for the better by empowering them to achieve their goals.

Volunteer Opportunities

Link Up Mentoring - NEW!

Bigs serve as mentors for a small group of high school students. Group mentoring sessions explore teens' interests and provide a variety of fun opportunities. Groups are facilitated by a BBBSF staff member alongside other mentors. 

Community Based In-Person Mentoring:

Spend time with your Little a couple hours a week, a few times a month.  You and your Little will participate in activities that you both enjoy or try new things together – play a sport, go for a hike, or cook a meal.


Community Based Virtual-Only Mentoring:

Meet with your Little virtually via video chat and/or phone weekly for around 30 minutes. Do simple things together you both enjoy such as – learning a new hobby, completing a craft, playing a virtual game, or just hanging out.

School Based Mentoring:

Bigs are matched with a Little in 1st - 5th grade at one of 5 local Elementary schools. Matches meet after school once a week for ten weeks in the Fall and ten weeks in the Spring semesters. School Based Mentoring focuses on developing friendships within the school environment and providing positive role models to the children in our programs. 

Step Up Mentoring:

A collaboration between Big Brothers Big Sisters of Flagstaff and Coconino Juvenile Court Services, Step Up Mentoring connects local teens to positive resources in their community with the help of appropriate adult mentors. Participate weekly in group mentoring sessions to explore teens' interests alongside other mentors and provide a variety of unique opportunities for success.
