Most people specialize in one or a few fields and progress up through them in what are often called stovepipes or fence pickets. Thornton (Tip) Parker has done the opposite by deliberately working on tasks that require knowledge of multiple fields. He is a generalist with more than forty-five years of widely diverse government and business experience in management, strategic planning, finance and accounting, manufacturing, marketing, personnel administration, transportation, technology management, large computer and information systems, intergovernmental relations, assistance management, and policy development.
