hey opened North Park Laundry Mat in 1975 when they bought the business from Earl and Mary Jane Caldwell. A couple years later they acquired the fire extinguisher business from Dillon Donohoe. It was about that time they moved to the apartment above the cleaners and out of the Union Pacific Railroad house. Dorothy was always busy. When she wasn't working at the cleaners, she would volunteer her time as a den mother for the Boy Scouts, taught Sunday School at the North Park Community Church, was in the Lady's Auxiliary of the V.F.W.; and was a Rebekah. As a Rebekah she was president of the club, district president, and state warden for the Rebekah's. She received the decoration of chivalry from the Rebekah's state organization in 1984, and she was an advisor for Theta Rho as well. She audited the books for the Rebekahs for several years, served many meals for the North Park Fair and V.F.W. Rodeo, North Park Rodeo, Never Summer Rodeo, along with her sister Rebekahs. She was instrumental in the Halloween Carnival the Rebekahs started before passing the Carnival to the local FFA Chapter. Dorothy and Chris had the cleaners for forty years. They retired in 2000 when they sold the cleaners. They moved to Yuma, AZ, and lived there all year long and would really enjoy the winters when their snow bird friends from North Park would come down to enjoy the winter. Dorothy was very active in her church, Gila Mountain Methodist Church and volunteered with the Helping Hands ministry. She made many dear friends over the years in Yuma and will be greatly missed.
