In January 1976, Dulaine became dance partners with Yvonne Marceau, who had arrived at the dance studio in 1973. The pair studied in England with John DelRoy, and won several awards. In 1984, they co-founded the American Ballroom Theater Company with Otto Cappel. The Company debuted at the Dance Theatre Workshop in October 1984, and toured widely in the late 1980s. From July 1989 to 1990, the pair appeared in Tommy Tune's Broadway show Grand Hotel, finishing with a five-month run in the West End.
