  Chadwick was a founding member of the software consulting company 29Labs, then went on to co-found DraughtLab in 2016, a successful software company that provides companies food and beverage sensory analysis software. Chad had many varied interests; he was a talented bass guitar player, avid downhill skier and skilled amateur photographer. Chad shared his keen interest in science and physics with his son Ben and enjoyed cooking with his youngest son Max.  On weekends he and Erinn enjoyed hiking with their children and two dogs.
