School Leadership

Read this message about Riordan’s next president, Andrew Currier, who will begin his tenure in July 2017.

Meet Our Principal – Vittorio Anastasio ’84

Vittorio Anastasio RiordanOver the past 25 years I’ve had the privilege of experiencing Riordan from many viewpoints as an alumnus, teacher, counselor, coach, and administrator. I truly believe that Riordan provides the best education for young men.

What impresses me most is something that is not easily found elsewhere: the genuine culture of Brotherhood. At Riordan, students treat their classmates like brothers and develop a deep spiritual understanding and purpose of helping others. This was the case when I was a student here, and continues to this day.

Part of the Marianist philosophy of education on which our school was founded is to educate the whole person. We utilize our rich academic program in conjunction with co-curricular offerings to build character and prepare our students for the world beyond high school. Moreover, we embrace a diversity of learning styles and challenge students to work to their potential.

The best way to learn about our school is to experience life as a Crusader. I invite all prospective students and families to visit campus and get to know our exceptional students. You will also get to meet our dynamic faculty and staff who help transform our students into young men.

Thank you and Go Crusaders!

It is his goal to guide students to become well rounded, thoughtful and faith-filled young men. Mr. Zumbado graduated from University of San Francisco with a BA in Economics and earned a MA in Diplomacy from Norwich University in Vermont.

Catherine Mifsud, Dean of Community Life
Catherine Mifsud is Riordan’s new Dean of Community Life and will oversee all aspects of student life, including Campus Ministry and Student Activities. She will also be leading Riordan’s Marianist Integration Team and teaching Sophomore theology.

Though she did not attend a Marianist school, Mifsud’s family connection to the Riordan community was a driving force in her decision to join the Administration. Her father, William Mifsud ’56, and uncles Ronald ’61 and Michael ’67 graduated from Riordan, and her uncle Fr. James Mifsud, SM was a Marianist priest.

A native of Hollister and graduate of the University of San Francisco with a major in Communication Studies, Mifsud earned a Master’s in Theology from Boston College. Since her graduation from BC, Mifsud has taught theology and served as Director of Campus Ministry and Dean of Students at coed and single-gender schools in Louisiana and California. Most recently she served as Dean of Students at her alma mater, Notre Dame High School in Salinas.

Mifsud is also the CEO and co-founder of a nonprofitorganization, Strada Leadership, which trains and develops student leaders in Catholic elementary schools.
