Steering the US Marina Group ship is a duo who have had extraordinary careers and are now sharing that knowledge under the USMG name. Individually, both Jim Bronstien and Kevin Quirk are known in the industry for their extensive experience and expertise in executive marina and boatyard management, oversight and analysis. Together, they have combined to create US Marina Group, a premier marina management company for marinas in the US and abroad. Between Jim and Kevin, they each have 30 years operating and/or owning the most iconic marina and boatyard businesses in the industry, so they undoubtedly know how to make a marine business successful.

Decades on Deck

From 50 slips to 500, from dry stack to superyachts, US Marina Group is well-versed in all aspects of operations, sales, marketing, customer service, and financial controls. In fact, the extensive backgrounds of Jim and Kevin include a history of long-term executive management and ownership at some of the most well-known marina facilities in the world including Bahia Mar, Pier 66, Rybovich, Saunders Yachtworks, and Marina Pez Vela. In addition to its expertise in all aspects of marina management, USMG also has decades of hands-on experience in marina and boatyard layout and design.
