At CenterOak, we invest in lower middle-market private companies, with a core team that has successfully invested together for over 20 years

Our team’s tenure is evidence of our effectiveness as a unit. In our collaborative investment process, we bring together the perspectives we earned throughout our professional careers, including being the CEO of a closely held family business, selling and operating the company with multiple private equity investments, and assessing deals as investment bankers, lenders, legal counsel, accountants, and consultants.

For more than two decades, our senior team has been working together to deliver advice and guidance to portfolio companies and their management teams to help create value for all stakeholders.
