Dietze Enterprises, Incorporated, (DEI) is a privately held company (established in 1989 and headquartered in Chicago, Illinois), fully owned by one person, Mr. Vaughn R. Dietze.  Mr. Dietze offers 30 years experience in the hospitality, travel, convention, exposition, trade show and meeting planning industry.  He is a member of numerous trade associations and understands overall industry dynamics.  Mr. Dietze founded DEI with the idea that a tradeshow manager should not have to hire a registration service contractor company to provide their exhibitors with a 'state-of-the-art" lead retrieval system. His approach to the management and execution of business strategies provides DEI with a competitive edge in capitalizing on their marketing strategies.  Mr. Dietze is an innovator and brings products and services to clients before competitors. The knowledge, experience, and contacts Mr. Dietze has accumulated over 30 years have led to changes in the traditional modus operandi of DEI.
