campuses became two separate institutions, and the La Sierra campus became La Sierra University. La Sierra remains a major feeder school for LLU particularly for its medical programs. After the separation, Fritz Guy became La Sierra University's first president. He was followed by Lawrence T. Geraty in 1993, Randal Wisbey in 2007, and Joy Fehr in 2019. In 1999, over 20 percent of the student body signed a petition criticizing the university's core curriculum due to its alleged lack of focus on the Bible, politically liberal leanings, and "subversive attacks on Christianity and monotheism". La Sierra sold approximately 200 acres of its land to a developer in 2000, in what the university described as "the most significant physical change to La Sierra in the institution's 78-year history." The land, which the school formerly used for agriculture and a dairy, became a planned development known as "Riverwalk". Biology curriculum controversy In 2009, the university's science curriculum became a subject of controversy as the school was publicly accused, primarily by former pastor David Asscherick, La Sierra University student Carlos Cerna, and former La Sierra University student Louie Bishop, of teaching exclusively evolution in its biology classes, which the accusers felt was contrary to the teachings of the Adventist church. Concerned about the allegation, a campaign collected over 6,300 signatures to an online petition which called for Adventist universities to teach the Genesis creation narrative. The university's board of trustees unanimously affirmed the Seventh-day Adventist Church's 28 Fundamental Beliefs but some viewed that as inadequate. In 2010, the regional accreditation agency responsible for La Sierra, the Western Association of Schools and Colleges, gave the university an eight-year accreditation extension despite concerns over academic freedom and institutional autonomy. La Sierra was accused of apostasy by the executive committee of the Michigan Conference, one of the church's regional governing bodies. In 2011, the denominational accreditation agency, the Adventist Accrediting Association, gave La Sierra an accreditation extension ending in 2012, but required it to make changes to better promote Adventist teachings. In June 2011, three La Sierra University staff members resigned after a recording surfaced in which they were heard consuming alcohol and speaking critically of church officials. They alleged that they were compelled to resign in relation to the ongoing controversy but the university denied those allegations; the staff members sued the university but lost their case. Later that year, the board of trustees voted
