Though some work remains on a $1.8 million expansion of the Longest Student Health Center, the facilitys renovation is close enough to completion to permit use of the new spaces. For visitors like student Hilary Ratliff, one area of obvious major change is the lobby, now more than twice the size of the original waiting area in the 38-year-old building. Ceremonies dedicating the expansion are planned for the summer. Assisting Ratliff is medical records supervisor Stanthia Oakley.
