I've had the pleasure of working with Derrick, on the FX team and as a partner, over 7-8 years. He always addressed me as 'Mark' or 'bud' and was always willing to go above and beyond to help. As someone based across the bid pond in Dublin, I never met Derrick in person. But I know how highly his colleagues in both New York and Buffalo regarded him. A very friendly, kind, thoughtful gentleman - I'm glad I got to get to know Derrick and as a result I am qualified to know how he will be missed by so many. Rest well, my friend, until we again meet.
