Background
Timothy “Tim” Callahan is a Principal and Board Member of Heartland Partners, a Midwest private investment group founded in 2014. Heartland describes itself as focused on investment, growth, and long-term retention, with an emphasis on preserving business legacies and creating value-added jobs in Midwestern communities.
Before Heartland, Callahan served as Chairman and CEO of Extrusion Dies Industries (EDI), a global service provider to plastics manufacturing companies. Heartland’s firm biography says Callahan and his partners bought EDI after a private-equity-fueled bankruptcy, restored it to a global leadership position in its industry, grew annual sales from $23 million to $50 million, and retired the company’s significant debt load.
Earlier in his career, Callahan held roles of increasing responsibility at EDI and Johnson Controls, focused on engineering and manufacturing. His education includes an Associate’s Degree in Tool Engineering from ITT Technical Institute and a Bachelor of Science in Industrial Technology from Eastern Michigan University.
Callahan’s background is operational rather than venture-style: his investing relevance comes from manufacturing leadership, turnaround experience, debt reduction, and scaling established industrial businesses.
