From helping with coordination of moves, storage, shipping, and anything else I needed, to playing softball together or just taking a break to talk about our kids, or to talk shit about our colleagues, he was always there. I always knew where to find Derrick whether that be Building 7, or third base, it's an absence I'm not going to easily get used to. His smile. His laugh. That way he leaned back and gave you a little head tilt with one eye almost closed while taking a drag from his cigarette if you needed a reality check. Crofoots, please know he was loved by all here at the lab, and our hearts go out to you. May you find strength in family and loved ones. Hold them tight. Derrick will be with us always.
