Downtown Gainesville stakeholders got a first look at the planned expansion of Brenau University into their part of town on Tuesday night. About 50 people, including local business leaders, downtown property owners and city and county government officials, got an overview from university President Ed Schrader of proposed changes with Brenau’s acquisition of the Georgia Mountains Center. The university plans to renovate much of the old convention center space and convert it to classrooms for graduate-level health care programs.
