Superior craftsmanship and dedicated customer service have been family traditions for five generations at Wm. J. Mills & Co. Known first as sailmakers, Wm. J. Mills & Co. came to Greenport at the tip of Long Island's North Fork in the late 19th century. William Mills, a Scottish immigrant, moved from Northport, on Long Island Sound, to Patchogue on the South Shore, and then to Greenport. A growth spurt in New York City led to greater demand for fish and for shipping in general. Greenport was the bustling place to be for recreational and commercial water-related activities.
