## About

Navigant Oak was formed in 2015 by Greg Boll after the 2014 exit of Cummins Bridgeway, the Midwest distributor of Cummins engines. The office manages family capital originating from that transaction and maintains headquarters in Northville, Michigan. Capital is allocated across buyouts and growth equity in manufacturing, distribution, services and real estate. Positions include direct co-investments and SPVs alongside fund commitments and secondaries. Geographic reach remains limited to North America. Confirmed holdings reference stakes in Calculated Risk Motorcycle Group and commercial properties in Michigan and Texas. The team consists of three named principals. Greg Boll serves as Principal and CEO. Aaron Cozart and Ethan Allen act as Managing Partners and co-founders. Both are sons-in-law of Greg Boll and participate in the Turnaround Management Association. The John and Marlene Boll Foundation operates as the adjacent philanthropic vehicle. Ownership remains fully controlled by the Boll family with no external limited partners disclosed. Decision authority rests with the three principals who also hold operating roles in portfolio companies.
