WATERVILLE, Maine — Colby College President William D. Adams announced on Wednesday that he will retire next year.

Adams, affectionately known as “Bro,” will retire on June 30, 2014. Michael Gordon, chief operating officer of New York-based Angelo Gordon and Company, will chair a search committee to find Colby’s 20th president.

“I am honored to have had the opportunity to lead such a remarkable place,” Adams said in a statement. “Colby is an outstanding institution; among the very finest of its kind anywhere. But the thing you notice, living and working on this campus among our students, faculty and staff and working with the college’s volunteer leadership, is that Colby never forgets that it is meant to grow and improve.”

Adams, who became president of Colby in 2000, led a $376 million capital campaign, the largest in Maine history, which included numerous building projects, the college’s expansion on the Colby Green and the gift of the Lunder College of American Art, said Colby spokeswoman Ruth Jacobs in a statement.

“He has been an extraordinary leader, mentor and friend to many across the entire Colby community,” said board of trustees Chairman Bob Diamond. “His positive impact on our curriculum, our physical plant and Colby’s broader reputation with alumni, parents and prospective students has been enormous.”

Before coming to Colby, Adams served as president of Bucknell University for five years. He also taught political philosophy at the University of North Carolina at Chapel Hill and Santa Clara University. He coordinated the Great Works in Western Culture program at Stanford University and was vice president and secretary of Wesleyan University. He is a graduate of Colorado College and the University of California, Santa Cruz.
