The company is owned and chaired by Jay M. Cashman, who remains the driving force behind its strategy and culture.

In recent years, Cashman has been active in dredging and marine infrastructure projects along the U.S. East Coast, including work in Jacksonville Harbor, Maryland, and Portland. The company is also involved in renewable energy and tax equity, positioning itself at the intersection of traditional heavy construction and emerging clean energy markets.

Jay Cashman, Inc. traces its origins to 1965, when teenage brothers Jay M. Cashman and Jamie Cashman started a snow removal company in Massachusetts. As Jay Cashman recalls, "It all began in 1965 when my brother Jamie and I started a snow removal company. We were two teenage boys armed only with shovels and determination." The venture quickly evolved into rubbish removal and masonry, laying the foundation for a construction enterprise. Over the following decades, the company expanded into increasingly complex heavy civil and marine construction, dredging, and related fields. It grew into a family of companies offering a comprehensive portfolio of services, including heavy civil and marine construction, dredging, renewables and tax equity, prestressed concrete storage tanks, energy, project development, barge and equipment leasing, and mechanical construction. The company has executed difficult projects worldwide, from offshore drilling to the largest remediation dredging project in U.S. history, earning national recognition for engineering significance. Under Jay M. Cashman's leadership as Founder and Chairman of the Board, the company has maintained a culture of innovation, encapsulated in its trademarked slogan "Think Impossible." The company remains privately held and is headquartered in Quincy, Massachusetts. In recent years, Cashman has been involved in major dredging and marine infrastructure projects along the U.S. East Coast, including Jacksonville Harbor, Maryland, and Portland, and has engaged with initiatives such as the Atlantic Resiliency Innovation Institute.
