Colleagues describe him as "I worked with David at both Ciena and Nortel where his considerable technical skills and calm, diplomatic demeanor were key assets to the team. His insight and ability to boil down a complex technical issue so the rest of us could not only grasp and understand the nuance, but also become opinionated and make decisions was key. In the rarefied world of telecom standards, he is a known and trusted authority. It would be a privilege to work with him again in the future." and "Dave was our lead system designer. He had a great understanding of the technology, the standards and the need to support the sales and manufacturing people.
