Jim Meyers
VP of Business Development and Partnerships

Jim is VP of Business Development and Partnerships for AT, and focuses primarily on new business development and consulting projects, as well as managing client and partner relationships.

After a long career as a mortgage lending professional, Jim was introduced to Bryan Hartsock and Mark Granquist, partners with AT, and started immediately ‘drinking from a fire hose’ to learn iMIS, IT networks, managed services, hosting and VoIP technology.

Jim works closely with both the AT iMIS consulting/deployment and network teams on new sales, deployment projects, and ongoing support and guidance.  One of Jim’s greatest satisfactions is fostering relationships with organizations to develop them into ‘full service’ clients – iMIS users, as well as hosting and managed services customers.
