In March 2006, Chef MacMillan was invited to The Food Network’s kitchen stadium to compete in an episode of the hit series, Iron Chef America.  Chef MacMillan was pitted against Iron Chef Bobby Flay in “Battle American Kobe Beef.”  Ultimately, Chef MacMillan’s cuisine reigned supreme, letting him claim victory over Flay. He is a regular on several of Food Network’s most recognizable shows, including Guy’s Grocery Games, Best Thing I Ever Ate, and Cooks vs. Cons, and has made multiple appearances on The Today Show. Chef MacMillan served as the Executive Chef for the Sanctuary at Camelback Mountain from 2001 through 2021 before transitioning to his current role of Director of Culinary Operations for Clive Collective and oversees the new restaurant concept Cala in Scottsdale, Arizona.
