After returning to Texas from abroad, Mayfield was appointed Director of Music for The Austin School for the Performing and Visual Arts, and also Executive Director for the Austin Brass Center, both 501-C3 non-profit organizations. He is currently Instructor of Trumpet at Texas A&M University in College Station, TX. Along with trumpet virtuosi Paul Merkelo and Rex Richardson, he is one of the three trumpeters in "NEXT" Ensemble, an international group that incorporates baroque, jazz and classical/romantic trumpet in contemporary/experimental settings. A firm believer in expanding the trumpet repertoire, Mayfield has premiered and recorded works by composers Eric Ewazen, James Stephenson, Eric McIntyre, P.K. Waddle, and Filip Sande of Norway.
