David Boyle

David A. Boyle is the Chief Executive Officer of Mid Oaks Investments LLC, a Buffalo Grove, Illinois private investment firm. He joined Mid Oaks in 2005 with a background in finance, M&A transactions, banking, and investor relations, and rose through the firm's senior ranks — long serving as a Managing Director and Chief Financial Officer — before being named CEO in 2025, when he assumed responsibility for all day-to-day operations of the firm.

Before Mid Oaks, Boyle served as Chief Financial Officer of Globe Union Group, a holding company whose subsidiaries are primarily engaged in the manufacture of plumbing products. He began his professional career at Arthur Andersen, where he advanced to Senior Manager in the Transaction Advisory Services group, giving him a deep grounding in deal diligence and transaction structuring.

Boyle earned an MBA from the University of Notre Dame's Mendoza College of Business and a B.S. in Accountancy from Northern Illinois University. He has served, and currently serves, on the boards of directors of various Mid Oaks portfolio companies.

Mid Oaks itself was founded by Wayne C. Kocourek (now Chairman) and is run alongside a small senior team including Vice Chairman Michael A. Kocourek and Managing Directors David L. Crouch and Daniel A. Nadler. The firm invests its own capital rather than managing outside limited-partner funds, which gives it flexibility on holding periods and exit timing.

• Invests Mid Oaks' own principal capital in middle-market companies "that possess a substantial opportunity for value creation" — no third-party LP fund, no fixed holding period
• Seeks to partner with entrepreneurial management teams with "the foresight and vision necessary to elevate an enterprise to the next level of performance"
• Targets established, profitable operating businesses (control buyouts/recaps), not early-stage venture or seed rounds
• Strong preference for manufacturing, plus distribution and services; will not invest in financial, insurance, real estate, oil & gas, or retail
• Focuses on North American companies, generally in the ~$25M–$250M revenue range
• Patient, long-term orientation: because it uses its own capital, the firm can hold investments until the right value-add outcome emerges rather than to a fund clock
