William and Joyce Nyilas established the Springfield company bearing their name in 1975. From the very beginning, Nyilas Cleaning Service was based on a philosophy of total customer satisfaction. Bill figured the best advertising was happy clients telling their friends about his great company. Thirty years - and thousands of satisfied customers later - Bill and Joyce decided to take it easy in 2005, selling the business to Darrell and Angela Tureskis. As the new owners of Nyilas Cleaning Service Inc., the Tureskis' follow the same policy of complete customer satisfaction.
