Big impact—proven results

We’ve always known we were making a positive impact on children and empowering them to succeed. A nationwide study confirmed it for us.

Each time Big Brothers Big Sisters pairs a child with a role model, we start something incredible: a one-to-one relationship built on trust and friendship that can blossom into a future of unlimited potential. And thanks to the first-ever nationwide impact study of a mentoring organization, we have the facts to prove it.

“My Little and I are both Hispanic females. I graduated from UCSD with a Bachelor’s Degree in Human Biology. I currently work as a medical assistant and I am planning to go to medical school in the future. A few weeks ago, my Little told me that after meeting me, she realized that she also wants to be a doctor and she said “if you were able to do it, then, I can do it too.” Hearing these words reminded me why being a Big has been one of the best decisions I’ve ever made.” – Big Sister, Manuela

For a few hours twice a month, you can ignite a child’s potential. Sometimes it’s as simple as grabbing lunch, going to a museum, or just taking a walk.
