Mark Langer, Managing Director at CenterOak Partners, reflects on the experiences that shaped his approach to private equity—from early grit and middle-market investing to deploying capital in Africa and building enduring CEO partnerships. He explains why servant leadership, trust, and long-term thinking matter more than control in lower middle-market value creation. Mark also shares candid lessons on risk-taking, mistakes, and navigating the non-linear reality of business building. This is a grounded, hard-earned perspective from someone who has seen the full arc of private equity—hit play.
