Message from the Dean

“The Greehey School of Business presented me with endless opportunities to develop myself academically, personally and professionally. My professors mentored me and helped me to make the most of my education. I gained the knowledge and skills needed to be successful after graduation. Most importantly, I was able to develop into a well-rounded, ethical leader fully prepared to go out and face the challenges of today’s evolving business world.” – Leanne Fuentes (B.B.A. ’16)

“I attribute my professional growth to St. Mary’s University faculty and culture. They taught me essential skills, such as how to communicate effectively, act with intention, be a good leader, and the list goes on. I had friends at big state universities who didn’t have the same opportunities I did at St. Mary’s. Given the smaller student body in the Greehey School of Business, the odds were in my favor to be selected for conferences, projects and leadership roles. To this day, my former professors know me by name, and we keep in touch.” – Lisa Martínez (B.B.A. ’13)
