“I am humbled and honored for this responsibility and privilege to work alongside our coaches, staff, student-athletes and all of Cougar Nation,” Santiago said. “BYU is one of the premier athletic programs in the country, but it is so much more than that—it is part of BYU’s sacred mission. We are blessed with incredible leadership in President C. Shane Reese and Vice President Keith Vorkink, as well as the university’s Board of Trustees chaired by the President of The Church of Jesus Christ of Latter-day Saints. We are here to build student-athletes academically, athletically, spiritually and to prepare them to go make a difference in the world. As an athletic department, we stand united in this charge.”
