Admissions Contact Information

David J. Holquin
Director of Admissions

Mr. Holquin arrived at Justin-Siena High School in the summer of 2004. He assumed the role of Director of Student Recruitment and Campus Ministry. Since then, he has spent time getting to know students, staff, and families in the Napa, Solano, and Sonoma counties.

When Brother Robert J. Wickman, F.S.C., named Mr. Holquin as the Director of Admissions, Holquin noted that he looks "forward to meeting each student and family as they discern which school is the right fit for them. Of paramount importance to me is that a student and family choose a school where each student will feel successful and welcome. Plus, it is always best when a family believes and supports the mission and tradition of Justin-Siena. That’s what makes our community so great!”

A product of Lasallian education himself (graduating from Christian Brothers High School in Sacramento and Saint Mary's College in Moraga) Holquin believes in the importance and the power of a strong Catholic, Lasallian education. "In a Lasallian school, lives are transformed, and that is no small task."
