Education That Makes a Difference. For more than 150 years. Niagara University has been educating students in the Catholic and Vincentian tradition. This tradition emphasizes ethics, lifelong learning, and service to others and prepares our graduates for lives and careers that are both successful and fulfilling. Within this site, you will learn how the university is making a difference in the lives of our students, and how those students in turn are using the knowledge gained here to make a difference on campus, in the surrounding community, and in the world at large
