After graduation and working in the field, Mario established his own shop in Brooklyn, NY serving the area's leading architects, designers and collectors. His shop handled projects that included new construction, renovation, millwork, furniture restoration and refinishing, architectural woodwork, and fixtures and furniture reproductions. His work has been featured in Architectural Digest, Country Living, House Beautiful, Metropolitan Home, Hudson Valley, McCalls, Fine Woodworking and the New York Times.
Mario has taught in the Restoration Department at the Fashion Institute of Technology in New York City for almost 18 years, as well as many of the leading woodworking schools in the country.
From 1992 to 1997, Mario directed the Warwick Country Workshops from a small barn behind his Federal period farmhouse. These specialized classes were devoted to traditional hand tool topics such as hand cut dovetails, carving a ball-&-claw foot, hot glue hammer veneering and planemaking. Today, he still speaks at regional woodworking organizations and clubs.
For the past 26 years, Mario has written extensively for the leading woodworking magazines (Fine Woodworking, Fine Homebuilding, Home Furniture, Popular Woodworking and American Woodworker), primarily focusing on traditional hand tool techniques and projects. He has written two books: Traditional Woodwork and Building Fireplace Mantels, both published by Taunton Press.
In 2017, Mario left PFW to pursue other interests, but will continue to write, build and teach at the Waldorf School of Philadelphia. PFW wishes Mario well in his new endeavors.
