Originally built in 1950 and last updated in 1972, Postle Hall received a $95 million makeover in 2020. Postle Hall houses the state’s only and the country’s fourth largest college of dentistry. To complete this renovation, the four-story eastern portion of the building was demolished, and 150,000 square feet of new space replaced it. New features of this space include pre-clinical simulation and technology labs, eight small-group student practice clinics, four ambulatory surgery units, an expanded radiology center and three new classrooms. The courtyard was also remodeled, creating additional civic space for the students.

Postle Hall includes a dental clinic that treats some 460 patients each day. To overhaul this dental hub, at 305 W. 12^th Ave., on the corner with Neil Avenue, OSU received $26 million in state funds with the remainder subsidized by the university through alumni and corporate partnerships. The OSU School of Dentistry awards degrees in dental hygiene, a Doctor of Dental Surgeries (DDS) and dental specialties, like orthodontics.
