About Us

For more than 30 years, Big Brothers Big Sisters of the Mississippi Valley has operated under the belief that inherent in every child is the ability to succeed and thrive in life. As a donor supported volunteer organization, Big Brothers Big Sisters makes meaningful, monitored matches between adult volunteers (“Bigs”) and children (“Littles”), ages 7 through 18, throughout eastern Iowa and western Illinois. We develop positive friendships that have a direct and lasting effect on the lives of young people.
