Vincent Troiano
I’ve used O’Sierras Construction Services multiple times over the years for both residential and commercial projects, and I continue to be impressed. He just completed renovations in my new office, and—once again—the results were outstanding. His attention to detail is top-notch, the quality of his work speaks for itself, and his rates are more than fair.
