Cornerstone Builders Group is owned
and operated by Leo Feola and Frank Cardone.

Leo Feola

Leo began his career over 20 years ago as a carpenter’s apprentice. Over the years he quickly evolved and went on to become a superintendent, project manager, and owner’s representative for both regionals and NJ based development construction firms. His reputation and impressive track record lead to several requests from clients and developers to oversee multi-million-dollar commercial, residential, and mixed-use construction projects. Leo’s solid reputation amongst his peers and consistent track record of successfully taking large-scale projects from contract development through construction completion despite potential logistical challenges separates him from the rest.

Leo’s true passion is taking raw land and creating a home or repurpose an existing commercial property. He has always been a leader in residential renovations but can bring the most value when the home owner can trust in his guidance. There are very few builders in Bergen County New Jersey that can produce a product consistently that meets the high expectations expected of a contractor each day.

Leo’s responsibilities include but are not limited to the management of large teams of field personnel and subcontractors ensuring adherence to deadlines, budgets, quality standards, plans and specifications. In addition, he is an expert in the management of design professionals, while adhering to production targets of ownership with the ability to quickly and creatively resolve issues as they occur.

On Leo’s downtime, he enjoys unwinding at his home in Franklin Lakes with his beautiful wife and daughter. He and his wife enjoy hosting at home and cooking for family and friends.
