Since the age of 12, Mark has been a natural businessman. Selling garbage bags door to door, the seed was planted early on for what would eventually become long-term success. After graduating from Indiana University – where he briefly owned the most popular bar in town – Mark moved to Dallas. After a dispute with an employer who wanted him to clean instead of closing an important sale, Mark created MicroSolutions, a computer consulting service. He went on to later sell MicroSolutions in 1990 to CompuServe.
