Big Brothers Big Sisters is one of the only prevention programs in Wyoming proven to affect a broad range of social issues. Program evaluations consistently show that after entering the program, children are less likely to become delinquent, use alcohol, tobacco or drugs, or drop out of school. Thus, investing in Big Brothers Big Sisters is more cost effective than investing in single issue prevention programs.
