A valet became a key source of support for cancer patients at a N.Y. care center

Kate Fink is a breast cancer survivor. It is a success she credits, in no small part, to the unlikeliest of people who work at her care center in Buffalo, New York: the hospital valet.

"Absolutely, I mean he's made an impact," the 41-year-old Fink told CBS News of the valet. "Not just me, but so many other people."

The person Fink speaks so highly of is Jon Avery, who parks cars at the Roswell Park Comprehensive Cancer Center.
