In a tradition that spans more than a decade, the School of Dental Medicine hosts a special "welcome back" event at the start of the fall semester for students, faculty and staff, and this year's activity was an ice cream social. Chilly Billy's ice cream truck pulled up recently in front of Squire Hall offering sweet treats. Dean Marcelo Araujo (center) joined the fun and welcomed all to the new semester.
