Mike Bruno has served as Managing Partner since 1989, and works with a balanced team of financial and operating professionals with extensive industry experience. Taking an active, hands-on approach to value creation, Stonebridge Partners has invested over $650 million of capital in 62 separate acquisitions.

The Partners and Principals at Stonebridge Partners bring over 160 years of collective private industry experience to the company, with an average of more than 17 years at the Firm. Everyone on the team possesses a strong background in finance and operations and is committed to executing a consistent long-term strategy to satisfy the Firm’s investors and the management teams of portfolio companies.
