About Us

A Personal Message:

Hello, my name is Patrick Mahler. My wife Teresa, and I are the Founders and Owners of Natural Stone Care & Restoration Co. I started in the specialized field of stone & tile restoration, honing, polishing, sealing and repair over 30 years ago in 1988. I was introduced to this specialty at the age of 17 right out of high school, and I still absolutely love what I do to this day. I have a passion for transforming surfaces and seeing my clients eyes light up when they see our results. It gives me a lot of great personal satisfaction.

We are a small, family owned and operated company that offers personalized service and customized results. Teresa is the Office Manager and I work in the office and in the field alongside fellow Owners and Project Managers, Tony Morgida and Brian Watanabe. We pride ourselves on being super friendly and accommodating, experienced, and highly skilled. Please call me to discuss your needs. All estimates are free of charge, and all work is satisfaction guaranteed! I look forward to speaking to you.

We are different. Why are we different? Because we pay attention to the minute details. Because we exceed expectations. Because WE CARE!
