After his return to the U.S. in 1980, Mantooth worked extensively as a pedagogue, arranger, and publisher in addition to performance. He taught at DePaul University and recorded with Phil Wilson, Ashley Alexander, and Kirsten Gustafson. He wrote music for Louie Bellson, Art Farmer, and Carla Helmbrecht among others.
