Sales, Service, and Support

For over 50 years, the Marinak family has been selling and installing IBM systems. Midrange Support & Service, Inc., founded by Steve Marinak III in 1993, specializes in IBM Power Systems with a specific focus on IBM i. In 2016, Champion Solutions Group acquired Midrange Support & Service, Inc. to bring our two companies together to provide customers with an extensive suite of offerings and unmatched technical expertise. Together, we can be your total solutions and services provider to help you unleash the business value of your IT investments for outcome-based results. MSSi is now a business unit of Champion Solutions Group.

The MSSi technical team consists entirely of former IBM employees. These technology experts hold and maintain multiple IBM professional certifications. IBM has awarded both Champion Solutions Group and MSSi the distinction of “Premier Business Partner”, designating us as a leader among its peers. Exceptional support, legendary service… It’s our name.
