A legacy

Built Across Generations

Arthur C.S. Choo founded his structural engineering practice in Boston in 1966 after an extraordinary journey that began in Singapore during World War II.

After immigrating to the United States with little more than determination and ambition, he earned degrees from the University of Oregon, Yale University, and Harvard University before contributing to some of Boston’s most recognizable landmarks, including the Prudential Tower, Boston City Hall, and the JFK Building.

His dedication to thoughtful engineering, civic leadership, and enduring construction helped shape both the city and the foundation of the firm today.

That legacy continues through the next generation.
