Construction and project management throughout the Caribbean

Marvin brings more than twenty-five years of construction experience to Sagoma, across hospitality, heavy industrial, educational facilities, custom homes and private island resorts. Throughout, he has combined a passion for the built environment with technical skill and a strong engineering background to deliver full-service solutions to a wide range of clients.

He has been President of Sagoma Construction International since 2011, responsible for establishing and maintaining the relationships that bring clients back. His dedication shows in the personal, hands-on service he offers — which is what makes a project not just successful but a good experience for the person who commissioned it.

Before Sagoma, Marvin worked on projects throughout the southeastern United States and the Caribbean. The value of assets he has managed across his career is in excess of one billion dollars.

• Chub Cay, Berry Islands, Bahamas$250M
• Grand Lucayan Resort, Freeport, Bahamas$235M
