Conifer, CO - We’re thrilled to announce the addition of Baer Consulting to the IT Service Alliance (ITSA) family!
Founded in 1982 by Duane and Marilyn Baer, Baer Consulting is a trusted leader in IBM mainframe support and managed hosting, proudly serving customers across government, healthcare, financial services, and education sectors. At a time when mainframes are finding renewed relevance in the AI era, Baer’s expertise in end-to-end mainframe software support—from the operating system to middleware and databases—positions ITSA to play a pivotal role in supporting critical IT infrastructure for mid-market and enterprise customers.
We’re deeply honored to continue Duane & Marilyn’s 40+ years of exceptional service, with Duane remaining as CEO and Marilyn enjoying a well-deserved retirement.
Our team is also at the center of everything we do at ITSA and all full-time employees at Baer Consulting are now co-owners at ITSA, sharing in the growth of our business. Together, we are building a platform that celebrates collaboration and innovation while driving operational excellence for our customers.
