Dossier Quotes:
Derek possesses all of the best technical skills you can ask for but combines it with a business acumen that is not easy to find. He can not only build anything you can imagine but he also understands its application from a business standpoint. This makes Derek a very valuable asset that I will always value and highly recommend.
