Audience members (alumni, current students and staff) shared what the department has meant to them as well. Gifts and appreciation were conferred to retiring Student Affairs Officer Glenda Jones. This most-loved department member served us for over a decade and will be missed by all. Best wishes were given to her as she enters this new stage of her life.
