About Us

Ontra Stone produces the finest custom quality natural and engineered stone kitchen counter tops, fireplaces, baths, vanities, and special project work in this part of the country. We are a Natural Stone Institute (formerly Marble Institute of America) Accredited Fabricator as of 2016, one of only five fabricators in Connecticut and about 100 in the nation to achieve accreditation though the most prominent guiding body in our industry. As a member of the Natural Stone Institute who set the standards in our industry, Buddy Ontra is known nationally for his passion for stone. Buddy was elected by his peers to the NSI (MIA) Board of Directors for a five-year term beginning in November of 2015. As a board member, he represents all facets of our industry from fabricators to installers to designers and architects for every state in New England, from Connecticut to Maine. The kind words and shared finished products of our homeowners have kept us in business for a decade and continue to fuel our desire to push the limits of design and the boundaries of our craftsmanship. The marble and granite craftsmen at Ontra Stone Concepts are widely known as the finest in the industry. Having moved from Monroe to Bridgeport in 2012, our fabricating and installing crews have been working together as a well-oiled machine for close to a decade and have the experience of working with all types of natural and engineered materials, from granite, marble and quartzite to quartz, sintered slabs like Neolith and Lapitec, and glass. Referrals are gratefully provided from designers, builders and homeowners who have often worked with us for years and multiple projects of varying scales.
