Tennessee Technological University is celebrating a century of education, a century that has seen the Cookeville campus flourish and grow from its humble beginnings as Dixie College.“Turning 100 is a big deal for anybody or any institution,” said Tennessee Tech president Dr. Phillip Oldham during his address Thursday to the Rotary Club of McMinnville. He, along with former school presidents Dr. Angelo Volpe (1987-2000) and Dr. Bob Bell (2000-2012), were in attendance. “It came from a grassroots beginning,” Dr. Volpe said.
