Embrace the Opportunity

“We have a tremendous opportunity in front of us. One person shouldn’t feel the pressure to uplift an entire community. When each of us individually does our part – together we embrace the opportunity and become a Big Brother or Sister and make a Big difference to a kid who needs it.”

Jordan, Big

We serve all youth, and any child is welcome, including those living in single parent homes, growing up in poverty and coping with parental incarceration.
When would I meet with my Little?
In the Community Based Program it’s up to you and your Little, but most matches meet on the weekends. Bigs and Littles in the Site Based Program generally meet after school or in the evenings.
How much does it cost to be a Big?
There are no additional expenses in the Site Based program outside of an occasional gift around the holidays. In the Community Based program Bigs are responsible for the cost of outings. However, we encourage no cost/low cost activities. We often provide Bigs with free tickets you can use to take your Little to sports games, museums, cultural events, etc. Also, your Match Support Specialist will let you know about low/no-cost events in the community.
Can I be a Big if I don’t know much about kids?
Yes you can! You’ll have a dedicated and professionally trained Match Support Specialist who will assist you throughout the duration of the match with helpful suggestions designed to specifically enhance your relationship with your Little.
How do you match a Big with a Little?
We conduct in-depth interviews with the Bigs, Littles, and parents/guardians enrolling in our program so we can get to know all parties and can make the best match! We make matches based on common interests, personalities, preferences, and geography
Where can I mentor?
Bigs are matched in our Site Based and Community Based program in our four county service area which includes Cook, Dupage, Lake County, IL and Lake County, IN.
How far will I have to travel?
We encourage Bigs in our Site Based program to choose a location they can commute to relatively easily. In our Community Based program we ask if Bigs are willing to drive up to 45 minutes but we try make matches where the Big and Little are within 30 minutes of each other. We recognize that lengthy travel takes up too much time and can undermine the longevity and quality of a match.

Yes! For more information click here.
What kind of background checks do you do?
All volunteers and employees are subject to background checks that include obtaining references from people who know them well. Also we conduct a National Criminal Background Check (recurs twice a month), Federal Background Check, DCFS Child Abuse/Neglect, Public Domain Search, Motor Vehicle Check, and fingerprinting. In addition, in our Community Based program, anyone who lives in the Big’s home who is over the age of 18 must complete a background check.
Can I volunteer even if I have a criminal record?
We handle this on a case-by-case basis. It is important that you disclose this to us and address it fully. In some instances an offense may not be an obstacle because it is minor or long ago. In other instances, for example a case that is still open, it is a disqualifier.
Can I still be a Big if I don’t have a car?
Yes. Volunteers who don’t have a car can be a Big in one of our Site Based programs. Additionally, volunteers can become a Big in our Community Based program if they own or have access to a car they are insured on, use Uber/Lyft, Zip Car, a rental car or CTA.

Going out for icecream, going to a baseball game, cooking a meal, visiting a museum – the Big and Little can decide what they want to do together! In the Site Based program fun and engaging activities are led by the Program Coordinator.
What outcome areas will I focus on with my Little?
