Two UCF alumni who have excelled in their careers and devoted decades of volunteer service to the university will speak at summer commencements Saturday, Aug. 3.

Ceremonies at the CFE Arena will begin at 9 a.m. and 2:30 p.m., with the procession of graduates starting 20 minutes before each ceremony. Doors will open about 90 minutes before each ceremony.

The speaker at the morning ceremony will be Micky Grindstaff, chair of the UCF Board of Trustees and a partner in the law firm Shutts & Bowen LLP.

Grindstaff is a past chair of the UCF Foundation and a past director of the UCF Athletic Association and UCF Alumni Association. He is a member of the College of Business Administration Hall of Fame, and he won the college’s 50th Anniversary Award for Excellence.
