MayDay Sioux Falls allows our community to join together in celebration and service. We will work across our city to make a difference. We will serve the agencies that meet the needs of the young, old, poor, lonely, sick and abused. These agencies serve our neighbors. And our neighbors have sounded their Mayday call. They need us. They need you. Join an S.O.S. Team today. Invite your friends. BE THE DIFFERENCE IN SIOUX FALLS!
