John Fish is an American businessman, the self-made billionaire Chairman, CEO, and sole proprietor of Suffolk Construction Company, the largest building company in New England. Born in Hingham, Massachusetts, his career is rooted in the essential construction and real estate sectors.

Fish was raised in a construction family (his father owned Peabody Construction) and graduated from Bowdoin College in 1982 with a degree in Political Science. His entrepreneurial journey began in 1982 when he and his father established Suffolk Construction Company (an offshoot), immediately placing it under Fish's control. He successfully overcame severe dyslexia (undiagnosed until adulthood), which led to a sense of humility and a keen ability to read a room and motivate others.

• Suffolk Construction Company (Chairman, CEO & Sole Proprietor): The core private asset, the largest building company in New England (responsible for projects like Boston's Millennium Tower and Encore Boston Harbor). He acquired 100 percent of the company in 2006.
• Overcoming Adversity: He successfully overcame severe dyslexia, which he credits with shaping his leadership and communication style.
• Civic Leadership: He is the Chairman of The Real Estate Roundtable and former Chairman of the Federal Reserve Bank of Boston.
• Academic Governance: He is the Chairman of the Board at Boston College, the first non-alumnus in that role.

John Fish's strategic genius was his commitment to high-profile construction projects and building strong community and client relationships (leading to high repeat business). He bought out his father's stake in Suffolk Construction in 2006, becoming the sole proprietor. Under his leadership, Suffolk grew into a national construction powerhouse, responsible for iconic Boston-area developments like Millennium Tower and the Encore Boston Harbor casino.

His structural contribution is immense: his role as Chairman of the Federal Reserve Bank of Boston and The Real Estate Roundtable reflects his influence over both regional and national economic policy. His attempt to lead the private effort to secure Boston's bid for the 2024 Summer Olympics (though unsuccessful) highlighted his profound commitment to civic development. His wealth is secured by the colossal, long-term, stable profitability of the construction and commercial real estate sectors.

John Fish's social impact is structural, stemming from Suffolk Construction's role as a massive employer and foundational provider of commercial, residential, and healthcare infrastructure (building a new facility at Brigham and Women's Hospital). His personal philanthropy is significant, supporting the Boys & Girls Clubs of Boston and receiving the Corey C. Griffin Humanitarian Award.

His structural contribution is tied to his belief that his dyslexia taught him a humility and unique ability to understand people, read a room, and communicate a vision, qualities he instills in his company's culture.

John Fish maintains the professional, composed style of a construction executive. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects stability and immense corporate authority, typical of a leader in the high-stakes construction industry.

Residing in Hingham, Massachusetts, his luxury is the immense security and financial reward derived from his multi-billion dollar fortune. His life is dedicated to construction management, civic leadership, and philanthropy.
