Make him a graduate of Atlas. He has a connection to the school; one of the others could be a teacher's assistant at the school after graduation while Carmine went on to contract to the SDC and various other business and wealthy people as a bodyguard. Another could have joined the Atlas Military (possibly even be one of Winter's subordinates). They can all get together regularly to hang out and catch up, or do things together like missions. Taiyang and Qrow were teammates and they stayed together after they graduated.
