In 2010, Munsil was named as the 6th President in the 50-year history of Southwestern College in Phoenix, Arizona. Munsil had been a member of the Board of Trustees for six years and an adjunct professor, teaching ethics, political science and pre-law courses at the College since 1994. In his first year as President, Munsil implemented a name change to Arizona Christian University, invited President George W. Bush to speak at the school's 50th anniversary, drawing 1,260 supporters and raising more than $1.5 million, and presided over the school's largest enrollment and largest freshman class in history. Under his leadership, ACU raised its visibility, expanded its course offerings and majors, undertook campus renovations and building projects, dramatically increased fundraising and experienced large enrollment gains. ACU seeks to attract students who will "transform culture with truth" – building biblical influence in every corner of society. In 2015 he wrote "Transforming Culture With Truth," explaining how ACU's Core Commitments reflect the biblical principles and values that built Western Civilization, and how young people committed to biblical truth are needed in leadership today. After four straight years of record enrollment, in 2017 Arizona Christian University was recognized for the first time in its history as a "Best College" by U.S. News & World Report, placing 16th among Best Regional Colleges in the 15-state Western region, and the highest-ranked university in its category in the state of Arizona.

2006 gubernatorial election
During the campaign, Munsil was endorsed by four Republican Congressmen from Arizona: Jeff Flake, Trent Franks, Rick Renzi, and John Shadegg. He was also endorsed by Senator John McCain and more than 30 state legislators. Early polls suggested that Munsil had significant ground to make up in the primary, indicating in July that he had a mere 12% of Republican voters behind him. Don Goldwater, nephew of the late U.S. Senator and U.S. presidential candidate Barry Goldwater, came in second in a four-way Republican Primary Election on Sept. 12th. Munsil received 51% of the vote, while Goldwater garnered 40%. Mike Harris earned 6% and Gary Tupper mustered 4%. In the general election, just 8 weeks later, Munsil was defeated by incumbent Governor Janet Napolitano by a 63% to 35% margin.
