While cooking for Wolfgang Puck after graduating from the CIA, Huppin began designing and making more comfortable chefs pants for friends, then friends of friends, in the industry. This led to the creation, in 1990, of Chefwear, Inc., a company that specializes in clothing and accessories for chefs. She has outfitted celebrity chefs such as David Burke '82, George Morrone '83, and Jonathan Waxman.
In addition to her successful catalog and Web business, Huppin is still a working chef. She is the executive pastry chef and founding partner of Beacon, an Asian-inspired café in the Culver City neighborhood of Los Angeles.
