While Jim Shooter acknowledges his own talent, he's also the first one to tell you he couldn't do it alone. There are a handful of people in the industry who have remained loyal to Shooter through the years. If you research Shooter's career, you'll invariably see some of the same names popping up, here is a incomplete list of the names I see repeatedly:

Chris Claremont
Geof Isherwood
Janet Jackson
Joe James
J.G. Jones
David Lapham
Christopher Priest
Pauline Weiss
