At this time, the College is planning to resume in-person, on-campus instruction, residence life, and student activities as permitted for the Fall 2020 semester. We are exploring various contingencies and measures that will be required to open the campus. Faculty and staff offices will reopen when the state allows as part of the phased reopening.
