Auxiliary groups, grants, foundations and corporate partnerships allow us to make meaningful matches between adult mentors and children in our local community. Their support helps ensure children in the Big Brothers Big Sisters programs live up to their full potential.


Beyond School Walls

This site-based program matches a local corporation with a school in our community.  Employee “Bigs” are matched, one-to-one with a student from the partner school and the matches meet in a group setting once a month at the partner corporation.  Learn More →

Sponsor a Match Activity

We coordinate a number of fun activities for our matches throughout the year—usually about one event per quarter. Some of our fun events include Snow Tubing and snow boarding, bowling, laser tag, camping, and a trip to Mosby Farms Pumpkin Patch each fall.

Invite a Big Brothers Big Sisters Representative to Speak

Can our staff come in and present about being a Big?  We are happy to come into your team meeting for as little as 15 minutes to educate your employees on the rewards of being a mentor to one of the children on our waitlist.


Does your company have products or tickets you can donate for our auction or for our kids?  Contact us to see if you have something we need!

Third-Party Events

Would you like to coordinate a golf tournament, run or shopping experience or other event with the proceeds benefitting Big Brothers Big Sisters?  We have a team dedicated to assisting you with event logistics, payment collection, social media, marketing and invitations.
