Paul quickly advanced through the ranks—earning his Master Oil License in 2015 and adding propane and natural gas credentials along the way. In 2014, he founded Spaulding Heating, now a trusted name in the Topsham area known for expert service and efficient energy solutions.
Paul joined our team in 2025, when he began working as an adjunct instructor to teach our evening propane and natural gas courses. He has since joined our staff in a more permanent capacity!
