TK Capital

Dennis J. Keller established TK Capital after co-founding DeVry Inc., now Adtalem Global Education. The office deploys family capital generated from that education business and industrial fastening operations. Multiple Keller family members hold principal roles and direct specific holdings. TK Capital acquires controlling interests in platform companies and works as an engaged owner. It deploys across private equity, direct co-investments, real estate, and select venture stages from seed through Series B. Confirmed activity spans North America with exposure to manufacturing, education services, and enterprise software. Portfolio examples include Sellers Manufacturing and Molten Metal Equipment Innovations. The team remains small and family-led with no disclosed headcount or additional offices beyond Lake Geneva. Dennis Keller maintains board roles at the Smithsonian Institution and University of Chicago. Templeton Keller serves as trustee at Loomis Chaffee School and holds an Ashoka Fellowship. Family principals retain direct operating responsibility for several portfolio companies, creating a hybrid owner-operator model distinct from typical outsourced family offices.
