phatch, I thought this to be only season 4.
First season the winner was Michael Wray and he accepted an offer to work with Ramsay in London, but later chose not to go because of "family issues"
Second season the winner was Heather West and she was named senior chef of Terra Rossa at the Red Rock Resort Spa and Casino. Her contract has currently expired and she is now a chef at the Broadway Grill in Seattle, Washington. Sounds like she traded up and made a good career decision.
Third season the winner was Rock Harper and he was named head chef of Green Valley Ranch's Terra Verde. Currently, he is no longer a day-to-day chef with the restaurant, and is instead handling public relations for Terra Verde and the Green Valley Ranch Resort. Judging from how he spoke to this years contestants he seemed to be well in control of his career and even though he's not the Chef, it sounds like he made a positive career choice as well. :chef:
