Why we chose it: The university's two-year IMBA (or, Integrative MBA) has been in existence for 14 years. The unique courses in this program 'integrate' all elements of starting a business by placing professors of different fields (marketing, accounting and finance, for instance) in the same classroom as part of the multi-faceted teaching method. The program emphasizes the use of the latest information technology in each startup plan. Louisville also provides specialized MBA programs for law, engineering and accounting students who have an entrepreneurial bent. And thanks to its strong Ph.D. program for entrepreneurship, the school is a research leader.
