Opened in Fall 2008, Sampson Hoffland Laboratories provides state-of-the-art facilities for the biology and chemistry departments. The 64,000-square-foot building, located adjacent to the east wing of Valders Hall of Science and boasting a range of "green" features, includes 17 teaching labs, faculty-student research areas, lab and research support/storage areas, 21 faculty offices, more than 4,800 square feet of study area, and space for collaborative student-faculty research projects. A multimillion-dollar naming gift for the building's construction and maintenance was given by Milton and Dorothy Roelfs of Escondido, Calif. Its name honors Dorothy's parents, Marie (Hoffland) and Freeman Sampson.
