Be a Defender of Potential

Become a Big

You can be the difference

All youth have potential, they just need someone to defend it. One-to-one mentoring provides young people with the support and opportunities they need to help build successful futures. Our Littles dream big, and our mentors empower them to reach their fullest potential.

There are a lot of Littles who want a positive role model in their life. We need more mentors to ignite the power and promise of our youth. As a Big, you’ll change a young person’s life, but they’ll also change yours.

Steps to becoming a Big

Join an info session

Sign up for an information session with our staff to learn about our different programs, what’s required, and the application process.

Step Three

Fill out an application

We’ll review your application to make sure you meet the requirements and run a background check.

Attend a deep dive session

You’ll get more details about the program, mentor expectations and the interview process. You’ll also learn more about the youth we serve and situations you might face as a mentor.

The interview determines if you’re accepted into the program. It’s also important for us to learn as much information about you as possible to make an appropriate match if you become a Big.

A lot of thought and intention goes into our matching process, so wait times can vary. We match mentors based on the best fit for you, the child, and their family.
