STS provides a cost effective alternative to in-house transportation headaches by providing competent staffing, proper bus maintenance, efficient and timely routing, and handling of normal daily bus issues.  FISD's relationship with STS remains positive because of their quality of service and understanding of the business.  We have contracted our bus services since 1995 and find that STS is by far the best value.
