Stone Masters Inc.

Award Winning Countertop Fabrication and installation


Dan DiTomaso

My favorite part about running Stone Masters is the stone. I love the stone. In fact, I am passionate about stone. Everyone who works with it is too. That is because it is stunningly beautiful. You never get tired of its beauty.

Just recently, I was asked by an interviewee, “What was my favorite thing about Stone Masters Inc.?” I had never been asked before, and I never thought about it but I found the words just came spilling out; “the stone”. If I was pressed for my favorite stone, it would have to be soapstone. That is the beauty of it. There is not right or wrong stone….only your favorite stone!

Our Story

Today, Stone Masters is family owned and operated by Dan and Ann Marie DiTomaso. I am Dan and this is how we became Stone Masters Inc.

The Beginning

Back in the 90’s  when Ann Marie and I started to remodel our own kitchen. We wanted granite. But, there were only 2 or 3 places and they were not friendly at all. In fact, they were demanding to know who our kitchen designer or builder was before they would even talk to us about stone! Still, we needed to select stone slabs.  Back then, there was the Yellow Pages and no internet. After a lot of searching we ended up at Lowes, only to be sent to a local fabrication facility. Unfortunately, they had a very limited and cramped slab selection. So, we thought to ourselves, “there must be a better way”.

Before we were in the stone business Dan and Ann Marie were buying, renovating and selling houses. And, all of the houses got granite kitchens and tile bathrooms. Dan would fabricate the stone counters and set the tile himself.  Red Barn Repairs is the name of this company.  Finally, Ann Marie would find, stage and sell those houses. We renovated scores of our own houses and got better at it with each passing home. Dan bought more and more stone working tools until we were fully equipped and started to do this for other people who saw our work. Pretty soon home buyers who saw our houses asked us to do the home they were selling to make it more marketable. And, on and on…

Feel Good Buying From “The Green Company”

Recycled and Green

The Stone Masters factory uses over 12 million gallons of recycled water per year in the manufacturing of our counter-tops. Hence, we maintain our on-site water recycling equipment. As a result, there is a combination of reverse osmosis, mechanical, cyclonic and gravity filtration to clean then reuse the water in our facility.

Environmentally Stewardship

All used cardboard, plastic and metal wastes are recycled in our recycling program. Plus, our new stone storage building was purpose built to make the maximum use of natural lighting via a 132 foot by 4 foot translucent light panel. So, free natural light eliminates 100% of energy waste during the day. This is supplemental to our electric overhead lighting. As you know, natural light can’t be beat for viewing true colors of stone slabs.
