Sean Cleary, Seclay's founder and President earned a BS in Mechanical Engineering from Western New England College and was awarded his first patent for structural mechanical design in May 1998. As a licensed California General Contractor he taught himself the art of marble and granite fabrication.

His designs were his own just as his creations were the result of a solo endeavour in hand-crafted stone work. His debut year was prolific, highlighted by a beautifully crafted 28 piece art-deco marble fireplace. Demand paved the way for many more original designs, each one the manifestation of his passion for engineering, design and for melding form and function without sacrificing one for the other.

In December 2000, he had the notion to insert narrow strips of granite into ten picture frames he was making as part of a 50th wedding anniversary gift for his parents. The seemingly simple process of inserting stone strips into the hardwood frames proved anything but. It was soon afterward that a better method came to mind resulting in the birth of PrecisionStone™ and the founding of Seclay.

By the end of 2004, Mr. Cleary had designed and equipped a facility to manufacture marble and granite Inlays - once again a solo project. His experience with an unusually wide array of tools and materials had served him well as the process that renders Seclay's products today is actually the result of combining tools, techniques and machinery used in stone fabrication, the machining of metal, woodworking, and resin casting.
