Description

The Mayo Clinic in Jacksonville opened to patients 30 years ago, including 2,700 people from 30 states who already made appointments.

When Mayor Jake Godbold talked in 1986 about Mayo in Jacksonville serving as the “medical center for the Southeast,” he was overstating the case at the time.

Not any more.
