(formerly Maria R. Massaro)

Maria M. Petrocco focuses her practice on diligently representing the interest of the landowners and mineral owners in oil & gas transactions. She has gained much experience with oil & gas leases, surface use agreements and royalty issues. Mrs. Petrocco has never represented the interests of the oil companies and remains loyal to the surface and mineral owners. Mrs. Petrocco represents landowners, developers, farmers and ranchers, investors, construction companies, owners of equestrian centers, and individual sellers and buyers in a variety of real estate matters. She has extensive experience in due diligence, acquisition and sales. She has also represented several landowners with title problems in quiet title actions. Her experience in the title industry compliments her real estate practice by giving her a thorough knowledge of available title products, title searches and settlement processes.
