At 17, I began heating courses given by what was then the Institute of Boilers and Radiation. My tech skills grew in the field as my role in the business grew more critical to its success and I received my NYC Master Plumber’s License on my first attempt in 1998. Today, with over 30 years of experience in my trade, I am the specifier of all heating products and designs for the company which I now own with my brother. My services extend from single-family residences to mid-rise NYC commercial real estate. GPH is currently under contract in some of the finest and largest renovation projects in NYC and are routinely asked to stay on the jobs to provide service and maintenance.
