Gary Fuller and I worked together early in my consulting career. He oversaw the network technicians; I ran the help desk, so we found ourselves collaborating a lot.

Gary was a friend the way many colleagues are friends — we enjoyed working together and schmoozed during breaks, but we didn’t socialize after hours. Older then me, and with more consulting experience, he also served as a mentor when I needed one, even when I didn’t recognize the need.
