What Crescentia Capital does
Crescentia Capital is the equity buyout business of Calvert Street Investment Partners, a Baltimore-based private investment platform founded in 1995. The firm specializes in control equity investments in lower middle-market companies with $3 to $15 million of EBITDA, targeting three core sectors: Industrial Services, Infrastructure Services, and Specialty Manufacturing. Crescentia partners with families, founders, and owner-operators, often allowing sellers to maintain minority ownership while providing growth capital, operational support, and a hands-on value-creation playbook led by dedicated operating partners. The firm has invested more than $635 million of capital across 70+ companies since inception.
Crescentia employs a thesis-driven investment approach combining in-house sector research with relationships cultivated by its operating professionals and industry advisors to source proprietary deal flow. Portfolio companies are built and scaled through a combination of organic growth initiatives and disciplined add-on acquisition programs, exemplified by TechPro Power Group's seven strategic acquisitions under Crescentia ownership and Synsus's expansion via AmegA Sciences, React Industries, and Emerald Bioagriculture. The firm exited Terra Nova Solutions to Clean Harbors for $225 million in 2026, sold TechPro Power Group to Integrated Power Services, and previously divested Premium Inspection & Testing to Acuren (American Securities).
The firm is led by co-founder and Chairperson Joshua Hall, Managing Partner Brian Guerin, and Partner and Chief Investment Officer Michael Booth, supported by a team of partners, vice presidents, associates, and analysts, plus a bench of operating partners who serve as board chairs or lead directors for portfolio companies. Crescentia's investor base includes institutional LPs, and the firm maintains relationships with buy-side and sell-side intermediaries who receive success fees for sourced investments. The 2024 rebrand under Calvert Street Investment Partners formalized Crescentia Capital as the dedicated equity buyout brand, with Parkway Capital operating separately as the platform's mezzanine debt business.
