Angelo and Mario D'Alessandro learned the art and trade of masonry from their father who ran a very successful family business for over 30 years. After working under the supervision of their father: a professional, successful, business owner and expert mason, and working together under the company name, Mario D'Alessandro Contractors, brothers Angelo and Mario decided to create A&M D'Alessandro Contractors in order to continue the traditions and craftsmanship learned over the three decades while incorporating modern designs, products and techniques. A&M D'Alessandro takes great pride in being family owned and operated, as well as fully licensed and insured.
