Who We are at Mark 3 Systems

Mark 3 Systems, Inc. is one of the nation’s leading Texas-based providers of enterprise-class servers, storage, and networking products and associated support services.  Leslie Powell, a third-generation Houstonian, formed the company in 1995 after a successful career in medical sales.  Ms. Powell was seeking a new challenge and recognized the tremendous opportunities available in the growing field of large-scale business computing.  She was one of the first companies in Houston to start a relationship with IBM that has continued ever since.

Over the past 15 years, Mark 3 Systems has grown from a one-woman enterprise to a $40 million company with a team of experienced IT account and technical professionals.  Because of our dedication to customer satisfaction and maintaining the highest level of technical skills, we still have relationships with nearly every customer we have sold to including our first one in 1995.  We sell to all industries and the public sector, and are please to have MD Anderson Cancer Center, Travis County, Woodforest Bank, Landry’s, and Baylor College of Medicine among our list of valued customers. 

The key to Mark 3 Systems’ success is credited to our uncompromising focus on total customer satisfaction.  In an industry often characterized as simply moving boxes, we custom-tailor a solution to meet each customer’s specialized requirements.  Our customers appreciate this, and consistently give Mark 3 Systems approval ratings in the high-90s.

Mark 3 Systems can help your company meet its information technology requirements with productive and cost-effective solutions now and in the future.  For more information on any of our products or services, please call us at 713-664-9850.  We look forward to working with you.
