Romans' communication is the best part. There is nothing unclear, and you're never left wanting to know anything. He is extremely clear and breaks things down for you. In addition, his system admin skills are really above what I've seen other senior admins be able to do. He is able to grasp completely new concepts with absolute ease and has fulfilled every project ahead of time.
