It has been a pleasure, educational experience, and an honor to have worked with David at two different companies… While at Sysomos, I reported to David and you could not ask for a better leader or mentor. He was born for a leadership role. It is his way with people and the ability to inspire – not just because of the fantastic work he produces. I will make sure that David and I work together again. You need to make it a point to work with him too.

David is one of the most forward-thinking digital marketers I know. His work ethic and desire to push clients in ways that get them outside their comfort zone is amazing. He’s a stellar speaker and does a great job relating emerging digital content and new technologies to why brands should care and how they can best take advantage. He is very passionate about what he does and a true team player. I enjoyed working with David throughout my time in the Agency Lead role!
