  He then immigrated to the United States, more specifically Palm Springs, California, where he was the Chef with Le Vallauris. Subsequently, Willem secured a position as a Chef at the Hyatt Grand Champions Resort.

  Willem continued his affiliation with Hyatt and moved to Dallas, Texas to work for the Hyatt Corporation. He later became the Corporate Chef for Sambuca Mediterranean Jazz Cafes.

  Willem and his wife, Amy, now reside in Boulder, Colorado. He is the Executive Chef for Celestial Seasonings and has also developed his own company: Guilluame's, Inc. where he is the CEO and passes his standards of excellence on to those working around him!
