## About

Marshall Street Capital was founded in 2014 by Thomas J. Hauske, Jr. The office oversees assets derived from the sale of operating companies previously held under the Everett Smith Group, including Albert Trostel & Sons and Eagle Ottawa. Hauske serves as Executive Chairman and also leads the Hauske Family Foundation. The portfolio allocates across private equity, direct co-investments, fund-of-funds commitments, hedge funds, private credit and real estate. Investment stages span buyout through late-stage growth. Confirmed geographic focus remains North America. The firm has shifted from direct ownership of operating businesses to a conventional mix of traditional investments while retaining exposure to industrial tech, supply chain, energy transition and healthcare services. Named partners include J. Douglas Gray and Bruce Betters, both former CEOs or CIOs of the office. No public headcount or AUM figure exists. The firm maintains its headquarters in Milwaukee with additional property holdings at 800 N. Marshall Street. Adjacent vehicles include the Hauske Family Foundation and participation in the Chicago Booth Family Office Initiative, where Montgomery sits on the steering committee. J. Douglas Gray holds board roles at Method Capital and the Chicago Council on Global Affairs. In the last 24 months no dated operational announcements have appeared in public records. A structural differentiator is the creation of Claridges Trust Company as a dedicated Tennessee private trust company that serves as professional trustee for family trusts, separating trust administration from the investment office while preserving family control through Hauske's chairmanship.
