How do you think studying business in Pacific Lutheran University?
It's a fine school, but you should apply to MBA programs that best meet your personal goals, so consider many different schools and apply to many different schools if possible.

The same goes for Seattle Pacific University and the University of the Pacific. Pacific University Oregon was founded in 1849 while Hawaii Pacific was founded over 100 years later in 1965.
