The following year, the graduate curriculum once again was expanded with the introduction of the master's degree program in business administration. Guillot also directed a substantial expansion of the university's physical plant, including the construction of the Education and Nursing Building (now Stevens Hall), additions to Collier Library, Flowers Hall, and the Student Union Building (later renamed Guillot University Center), and renovation of Braly Municipal Stadium. Following a reorganization in 1991, the university's administrative structure consists of four divisions: Academic Affairs, Business Affairs, Student Affairs and Advancement, each headed by a vice president. In 1993, the Board of Trustees, anticipating continued and steady enrollment growth, adopted a new master facilities plan to ensure that UNA ultimately will be equipped to accommodate 10,000 students. Robert L. Potts, who succeeded Guillot following his resignation in 1989, undertook a series of measures to compensate for shortfalls in state funding, including the reactivation of the UNA Foundation as the university's charitable arm. Two other measures included the reorganization of the alumni relations department and provision for an annual giving program. Curriculum expansion continued with the establishment of new graduate programs in English and criminal justice. The university's nationally renowned commercial music program was enhanced with the development of an Entertainment Development Center. UNA also emerged as an early leader of distance learning. International student enrollment also underwent explosive growth. By 2004, international enrollment increasing to nearly 300 students representing 35 countries. William G. Cale Jr., became president of the University of North Alabama on January 15, 2005, four days after the university marked the 175th anniversary of its founding as LaGrange College. A Philadelphia native, Cale came to UNA from Pennsylvania State University-Altoona, where he served as chief executive officer and dean. Previously, he was the executive vice president for Academic Affairs at Lamar University in Beaumont, Texas. After an interim by John G. Thornell, then vice-president, the presidency was assumed in 2015 by Kenneth D. Kitts, formerly provost at the University of North Carolina at Pembroke. Kitts also taught at Francis Marion University in South Carolina, the University of South Carolina, and Appalachian State University in North Carolina.
