People searching for “Ralph Stone and Company” are usually looking for one business: Petrillo Stone Corporation, the Mount Vernon, New York stone company co-owned and run by Ralph Petrillo. It is a family firm with more than a century of work behind it and a portfolio that runs through some of New York City’s most recognizable buildings.
Here is who Ralph Petrillo is, what his company does, and why architects, contractors, and homeowners keep coming back.
Who Is Ralph Petrillo?
Ralph Petrillo is part of the third generation of the Petrillo family to lead the company. He and his brother Frank are the grandsons of founder Antonio T. Petrillo, who established the business in Mount Vernon in 1907.
Ralph grew up around the shop, worked there as a young man, and now runs the business. He graduated from the University of North Carolina and holds an MBA from Iona College. Read more about Ralph Petrillo and his role in carrying the family tradition forward.
A Family Company Built Over Three Generations
The Petrillo family has stayed in the business since its founding, and its fabrication shop has operated from the same Mount Vernon location since 1926. That continuity is rare in any trade, and especially in one that depends so heavily on skills passed down by hand.
Ralph has spoken about the business as a link between three generations of craftsmanship and ideas. His own early memories include his father and uncle, John and August Petrillo, fabricating the travertine for Lincoln Center in the family shop during the 1960s.
What Ralph Petrillo’s Stone Company Specializes In
Petrillo Stone imports, wholesales, fabricates, and installs natural stone. That full range means one company can source the material, shape it, and set it, rather than splitting the job across several vendors.
The core materials are marble, granite, and limestone, along with bluestone, brownstone, and other natural stones, much of it imported from quarries around the world. The work spans interior and exterior applications, from facades and lobbies to kitchens, fireplace surrounds, and carved architectural detail.
Old World Craft Meets Modern Fabrication
What sets Petrillo apart from a typical stone yard is its blend of traditional hand skill and modern technology. The shop pairs hand carving for intricate detail with modern cutting equipment for precision and scale.
That balance lets the company handle both restoration and new construction. A hand-carved column or a restored historic ornament calls for traditional technique, while a large contemporary facade benefits from machine accuracy, and the same team can deliver both.
A Portfolio That Shapes New York City
The clearest evidence of leadership is the work itself. Petrillo Stone’s projects include the St. Regis Hotel, Rockefeller Center, and Lincoln Center, along with 11 Madison Avenue and the former AT&T Building.
The company’s relationship with Fordham University dates to 1936, when Antonio Petrillo took the contract to fabricate the cut limestone for Keating Hall at the Rose Hill campus, much of it hand-carved. Eighty years later, in 2016, the Petrillo team carved and installed a 16-foot Fordham seal finished in 23-karat gold leaf at the Lincoln Center campus.
Why It Pays to Source Stone From an Industry Leader
Stone is one of the most permanent decisions in any building, and mistakes are expensive to undo. An established supplier and fabricator brings decades of solved problems to your project, from reading a slab correctly to planning delivery around New York job-site constraints.
Experience also protects your schedule and budget. A company that controls sourcing, fabrication, and installation in one place has fewer handoffs where errors and delays creep in, and one team accountable for the result.
Finally, a long track record means proven quality. A firm whose stonework has held up on landmark buildings for decades has already demonstrated what newer outfits can only promise.
What Sets Petrillo Stone Apart
Several things distinguish Ralph Petrillo’s company in a crowded market. The first is longevity: well over a century of continuous operation under one family.
The second is in-house control. Because Petrillo fabricates in its own shop, it manages quality from the slab to the finished installation instead of outsourcing it. The third is local knowledge, built from generations of work on New York’s historic and modern buildings, which matters when a project involves landmark restrictions or older structures.
The fourth is range. The company works with architects, designers, contractors, and homeowners alike, applying the same standards to a hotel lobby and a residential kitchen. To learn more, see why architects and builders choose Petrillo Stone.
Working With Ralph Petrillo’s Team
Whether the project is a landmark restoration, a commercial interior, or a custom piece for a home, the process starts with understanding the design and selecting the right material. From there, the Mount Vernon shop handles fabrication, and the team manages installation.
