Over the course of our 135-plus years in business, one thing has remained the same: We're a family business! Wm. J. Mills & Co. is currently owned and operated by the fifth generation of the Mills family.

Our customers come to us for quality in both the goods we produce and the service we provide. All of our products are handcrafted in our shop in Greenport, N.Y. on the North Fork of Long Island and certified Made in the USA!

In our 15,000-square-foot shop we boast new computerized stitching machines, the largest computerized cutting table on Long Island, the largest sail loft on Eastern Long Island, and a fully equipped machine shop with custom-designed fabricating equipment.

Cumulatively, our manufacturing staff has over two centuries of experience! We employ a full-time, professional staff that handles the installation of all our products and man a fleet of six trucks, all of which are on the road daily during the height of the season. Our staff is quick and efficient, leaving only the finished and installed product behind.
