    Leslie T. Powell

    President, Co-Founder

    In 1995 Leslie Powell saw the early trend in Information Technology to move sales into the channel. As a long-time sales representative in the healthcare industry, Leslie took the opportunity to start Mark III Systems, which focused initially on IBM IT infrastructure, but has since expanded to all aspects of IT infrastructure, software, services, cloud, cognitive, and digital. With her sales background, Leslie understood the value of having strong resources to support our customers, which is why Mark III has a ratio of close to 3:1 system engineers to sales reps and a team of DevOps engineers and developers to assist clients with digital and cognitive initiatives. This formula has led Mark III from humble beginnings to one of the most innovative IT solutions providers and IBM Platinum Partners with clients all across North America.

    Leslie is a graduate of The University of Texas at Austin. She is a widow with two wonderful sons. An avid reader, Leslie is the best customer of the Friendswood Public Library. She enjoys traveling, and her favorite hobby is hunting for sea glass on quiet beaches.
