...University is truly a unique and student success focused institution.” I have shared that statement with numerous groups and it simply summarizes my basic philosophy of what Sullivan is all about. When I say that Sullivan is “student success focused,” I feel as President that I owe a definition of this statement to all who are considering Sullivan University. First, Sullivan is unique among institutions of higher education with its innovative, career-first curriculum. You can earn a career diploma or certificate in a year or less and then accept employment while still being able to complete your associate, bachelor’s, master’s or doctoral degree by attending during the day, evenings, weekends, or online. Business and industry do not expand or hire new employees only in May or June each year. Yet most institutions of higher education operate on a nine-month school year with almost everyone graduating in May. We remained focused on your success and education, and continue to offer our students the opportunity to begin classes or to graduate four times a year with our flexible, year-round full-time schedule of classes. If you really want to attend a school where your needs (your real needs) come first, consider Sullivan University. I believe we can help you exceed your expectations. Since words cannot fully describe the atmosphere at Sullivan University, please accept my personal invitation to visit and experience our campus for yourself. Sincerely, Glenn D.
