Thereafter he stayed busy performing hither and yon in the greater Los Angeles area, including 30 years with the Pacific Symphony, 24 years as a founding member of the Hollywood Bowl Orchestra, 12 years in the Composers Brass Quintet, and of course, a decade or so in Hoyt Bohannon’s garage on Tuesday nights.

He has been a member of the Bill Watrous Refuge West Band, the Jack Sheldon Orchestra, the Jimmy Cleveland Orchestra and did two, all too short, tours subbing with the west coast iteration of the Toshiko Akioshi-Lew Tabackin Big Band.
He is presently retired from low brass performance, serves as president of Local 7, American Federation of Musicians, and has taught trombone at California State University, Fullerton for more than three decades; where he co-founded (with Jeannie Little and Alex Iles) Trombone Day in 2004.
