48-year-old T. Colm O’Callaghan (his first name is pronounced more like “column” and less like “colm”) started in the hotel business at a 14-room hotel in Killarney, Ireland that was owned by his parents. In the late 1980s, he traded experience working in England, France, and Switzerland for New York, California, and Chicago. He was hotel manager at The Peninsula for three years and general manager of Conrad Chicago for two years.
