Not only did his professionalism match his depth of knowledge, but his dedication to the mission of improving the lives of veterans was unequalled. I learned a great deal from David, and would relish the opportunity to work with him again, on any project, in the future. To say he is an asset to any company is an understatement." and "Dave was a tremendous mentor at AT&T.
