Wow, so sad. So many outstanding memories of Dave. Although I had a couple nice contacts with him in Colorado after he retired the majority of my good fortune with Dave was in our work practice. As a young naïve and sometimes careless design build contractor trying to find my way Dave was an integral part of the early days and was the discipline we needed when we needed it. He was also creative, fun and brought enormous energy to all of our teams, and I’d like to think a lot of that rubbed off on me. All the Clark, families prayers, and thoughts.
