The Ridgebury team is composed of dedicated investment and maritime professionals infused with a dynamic, entrepreneurial spirit that continues to deliver operational excellence.

Robert P. Burke

Chief Executive Officer

Robert Burke

Westport, CT

After graduating from the US Merchant Marine Academy, Bob spent three years sailing US-flagged tankers as a ship’s officer. This gave him plenty of time - while studying the horizon - to think of other more dynamic aspects of the global shipping business. Coming ashore to obtain his MBA at Columbia, Bob enjoyed a number of operating and banking roles before joining GE Capital, where he ultimately ran the maritime structured finance division. After founding and running Great Circle Capital with Hew in 2000, Bob left to organize the highly successful purchase of Chembulk, where he served as CEO until the firm was sold in early 2008.

Fun fact: Bob’s maritime life began at age twelve, working at the family’s drydock and repair yard, Union Dry Dock – which operated as the last such facility along the New Jersey waterfront until its sale in 2017.

Hew Crooks

Chief Financial Officer

Hew Crooks

Westport, CT

Beginning a traditional investment banking and private equity path in New York at Lehman Brothers and Investcorp, Hew changed gears when he moved to Peru and founded an investment firm focused on privatizations and infrastructure investment. Later expanding to Eastern Europe, his experience spanned industries including steel, mining, agriculture, power and shipping. Hew met Bob Burke in 2000, when they merged their respective business efforts to form Great Circle Capital, where Hew focused on logistics, infrastructure, ports and terminals.

Fun fact: Hew spent three years as SVP Operations with Safe Water Network, a developer of drinking water projects in Ghana and India. This innovative NGO now serves 1.3 million people in 389 communities with affordable, safe drinking water.

Nikhil Sarna

Vice President, Finance and Operations

Nikhil Sarna

Limassol, Cyprus

Nikhil brings a unique combination of financial acumen and practical maritime experience to Ridgebury. From 1993 through 2006 he sailed for various companies including Maersk, Bergesen, OMI and others, reaching the rank of Master Mariner. He followed this with an MSc in trade and finance at Cass Business School, then joined a leading ship manager and investment company in a finance and business development role. There he was involved in negotiating a wide range of successful creative solutions and restructurings to bring the business through the aftermath of the financial crisis.

Fun fact: Despite hating cold weather, Nikhil sailed for an entire winter on an ice-classed tanker in the Baltic Sea. Compared to that experience, life at Ridgebury is quite tolerable.
