Mark is probably best known for his Mastering Windows Server and Complete PC Upgrade and Maintenance Guide books, both of which have seen more than 12 editions and sold over a million copies. An audience member at a recent talk remarked that he believed that Mark could "do a talk on watching paint dry that would be so good that people would be motivated to go home and paint a wall just to experience the joy of drying paint." While this has led to many very tempting offers from the likes of Sherwin-Williams and Behr, he's decided to stay with his first love... technology. Mark's humorous, provocative and yet informative style makes him a favorite of audiences around the world. Mark's firm, MR&D, is based in Pungo, a town in Virginia's Tidewater area which is distinguished by having one and only one traffic light.
