Old Ironsides Energy, LLC was founded in August 2013. The firm’s principals began working together when the economic drilling and development of unconventional plays was beginning to emerge as a nascent industry. Since then, unconventional drilling has grown to become the primary driving force behind the U.S. energy industry, making vast new hydrocarbon resources available for drilling and development, and along with them, the need for new processing plants and pipelines to move the oil, natural gas, NGLs and refined products to domestic market centers and international export facilities.

Since the firm’s founding, we believe the Old Ironsides team’s experience and investment philosophy has produced a record of value creation, represented by a mixed portfolio of more than 20 upstream and midstream companies and drilling joint ventures.

USS Constitution

Why are we called
“Old Ironsides”?

Our name comes from a famous piece of U.S. Naval history. Commissioned in 1797, the USS Constitution was one of the original six ships of the U.S. Navy. The Constitution is a wooden-hulled, three-masted heavy frigate. Moored today at the Charlestown Navy Yard in Boston Harbor, she is the world's oldest commissioned naval vessel still afloat. The ship was nicknamed “Old Ironsides” by her crewmen after an opposing ship’s cannonballs were seen bouncing off the oak sides of the Constitution during the War of 1812. The British vessel that was engaged in the battle with Old Ironsides was heavily damaged and eventually surrendered. (Source:
