Brother William Mann, who has served as president of Saint Mary's University since 2008 - is stepping down in May.
70-year-old Mann announced his departure Tuesday in a university-wide letter, writing that it's time for him to return home to the East Coast, and to spend more time with his family.
He says, "While I am in good health, it seems appropriate that I prepare to change the intensity and the pace of (my) activities."
He began his career as an English and religion teacher at Christian Brother high schools in New York and Rhode Island, before holding a number of leadership positions within the Christian Brothers.
Mann served on the Saint Mary's Board of Trustees from 1996 to 2001 and was a well-known member of the Saint Mary's community when he was named the university's 13th president in late 2007.
Under Mann, Saint Mary's has achieved historic levels of fundraising success, more than doubling its average annual proceeds.
Chair of the Board of Trustees, Mary Ann Remick, says -"In a time of immense challenges for higher education, Brother William has provided Saint Mary's University with a clear, innovative and strategic path for a strong future. His successor will have big shoes to fill."
The Board of Trustees will begin the search for Mann's successor in the coming weeks.
