Since 1981, TanTara Transportation Corp. has called a few places home. Mike Riggan started the business in his home garage. He then moved to a small two-stall garage with an office that had room for just four desks.?As Mike continued to grow TanTara, he purchased a 12-acre lot where he built a 10,000 square foot maintenance shop. We are located in the Muscatine Industrial park, near the Mississippi River.
