ORONO, Maine — It’s a big day for college commencements with ceremonies being held at the University of Maine System and other campuses across the state.

Entrepreneurs Heather and Abe Furth are the keynote speakers Saturday at the 215th commencement exercises at the University of Maine. The two met at UMaine in 1999, and have founded restaurants, a brewery and a property company.

Commencements are also being held at other University of Maine System campuses: Fort Kent, Presque Isle, Farmington, Machias and Augusta, along with the University of Southern Maine.

Unity College, St. Joseph’s College and the Maine College of Art are also holding commencements. Bates, Bowdoin and Colby colleges hold commencements later this month.
