Larson went to FCC in 1977 to serve as director of institutional development.
He was promoted to his current job in 1979. Larson developed the campus master plan and supervised the planning and construction of the college's most extensive capital improvements project, including the Arts and Student Center, the Children's Center, library and other major campus renovations.
Prior to coming to the college, he served as director of community services at Berkshire Community College in Pittsfield, Mass.
Larson earned a master's degree in government and politics and a doctorate in higher education administration from the University of Maryland at College Park. He received bachelor's degrees in English and government at Norwich University in Northfield, Vt.
Members of the public will be able to question Larson, Spencer and Donohue during community forums scheduled for next week.
The forums are part of each candidate's two-day interview process, which also includes meetings with students, faculty, support staff, administrators and college trustees, said FCC spokesman Michael Pritchard.
The board of trustees is expected to make a decision by early November.
Frederick Community College President Lee Betts will retire at the end of December after 11 years at the college's helm.
