“I worked as a peer of David's for the past 10+ years. Consistently during that time he continued to impress me with his extensive knowledge and experience in the Construction Industry. He is a very effective Senior Project Manager, and he is also an effective leader of Project Managers. He continuously analyzes projects (from conception through completion) to keep the costs as low as possible balanced with high quality and with an eye toward meeting set deadlines.
