About

Long Island Waterjet

Long Island Waterjet is a precision waterjet cutting shop in the heart of Long Island. This family owned and operated small business was started over 23 years ago by the company's previous owner, Ron Dennison. With a passion for metalwork throughout his whole life, Ron wanted to start something different after owning a welding shop for over 17 years. He took a leap of faith into the waterjet cutting world, without knowing how to operate such a machine, but he knew it was something he wanted to learn and become a master of after seeing a waterjet machine in action one time.  Fast forward just a few years and he had become a master of the trade, and had built a business to be proud of, a business that could be carried on, and a business his son would be proud to take over one day. Now owner-operator A.J. Dennison also has that same strong passion for metalwork that was taught to him by his father. After working together everyday for nearly 13 years to build the business to where it is today, with a nice spacious shop, and three OMAX waterjet machines, Ron Retired in January 2024, leaving behind a business legacy with big shoes to fill! A.J. is always up for the challenge, and is ready and eager to help on any project you may have pertaining to waterjet cutting!

Our three top-of-the-line OMAX waterjet machine centers can cut virtually any material, minus a few, up to 8 inches thick. We'll turn your project around quickly and accurately and specialize in precision cutting of letters, signage, shapes, and custom truck and car parts all the way to machine parts. If you can think of it, chances are we can make it.

We are always open to the public for walk-ins, and we have the flexibility to do small runs or large quantities with the fastest turnaround times. We stock the most common metals, including steel, stainless steel, and aluminum in various sizes and thicknesses to help with faster turnaround time for our customer's projects. Feel free to stop in and ask any questions or contact us. We are always willing to lend a helping hand, so come on in to meet us. We are happy to show everyone our shop and what our machines are capable of!
