Position: President
Region: Bluffton, SC
Contact #:  (843) 815-9931

John retired as the Chairman, President, and CEO of Coltec Industries in 1999 after merging his company with Goodrich Corporation. Being an avid boater and golfer, he and his wife, Monique, chose to relocate from Oxford, Maryland to Colleton River Plantation in Bluffton, South Carolina in July, 2008. While making several modifications to his new home, he was encouraged by his contractor to foam his attic to provide a more comfortable and efficient ambient temperature and his crawl space to seal out moisture as a preventative measure for any interior floor damage due to moisture and to also make the HVAC ductwork more efficient. This improvement was contracted to Energy One, LLC. John was so very pleased with results of the applied insulation and impressed with the equipment and personnel of Energy One that he decided to purchase the company and relocate it from Claxton, Georgia to Bluffton, South Carolina in October 2008. John also opened up a branch in Charlotte, North Carolina. John takes great pride in being the very best in the business of providing the proper spray foam insulation to both new construction, existing residential homes and commercial buildings.
