Corey has graduate degrees in Mathematics and Statistics. He has worked as an engineer for Intersil, a financial manager for Ryder, and as a business change manager for DHL's international businesses in the Caribbean. Managing 33 islands for DHL, each with different languages, legal systems, cultures, currencies, propensities for disasters (mud slides, volcanoes, kidnappings, hurricanes, etc) and widely varying political structures was a life lesson in diversity and adaptation. Corey left DHL in 2004 and started his own international shipping company which he sold in 2007. In 2007 Corey joined Lou Carter, the president of The Best Practice Institute, and together they are making organizations better by helping identify and implement organizational and individual best practices.
