In the 1970s, Mr. Jay M. Cashman founded his first company, J.M. Cashman, and quickly established a strong reputation for performing heavy civil and marine contracting projects throughout the Northeast. Notable work included reconstructing destroyed seawalls and jetties after the Blizzard of ’78 and developing a new marine facility in Martha’s Vineyard for the Steamship Authority and small dredging projects throughout New England.

Throughout the 1990s, Mr. Cashman established Jay Cashman, Inc. and continued to expand and prosper - executing major, large-scale heavy civil and marine construction projects and dredging projects primarily using mechanical dredges.
