Thirty years ago, Don discovered a way to combine his passion for travel with his love of marketing when he founded MMGY Global. He credits a degree in architecture for his obsession with building things. In the case of MMGY, his resulting legacy is the largest and most respected marketing firm in the world that specializes solely in travel and hospitality. In 1997, Don created the Vail Summit as a think tank for the top marketing minds in the industry. Now approaching its 20th year, the Summit has attracted brand leaders from around the world.
