Mad River Valley Ambulance Service: Since 1970, the Mad River Valley Ambulance Service has been providing 24-hour Emergency Medical Service to residents and visitors of the Mad River Valley, and Sugarbush and Mad River Glen ski areas. Since its inception, MRVAS has undergone considerable growth to keep pace with the growing needs of the community, as well as advances in emergency medical care. Our donation enabled MRVAS to invest in their new ambulance rig!
