Our Team

Stefan Cazzonelli has been a valuable member of the Parameter team since 2015, and in 2017, he was named sales and marketing manager. Cazzonelli works directly with clients to understand their temperature and humidity control needs and to offer them energy-efficient and cost-effective solutions most appropriate for their circumstances. Originally from Germany, Cazzonelli came to the United States as an exchange student in 2008 with the goals of learning English and experiencing a different culture. He graduated from Montreat College in 2015 with a bachelor’s of science degree in business administration, and concentrations in international business, management and sports management, and he now calls Black Mountain, N.C, home.

Adam has extensive experience in the service industry and applies that expertise to his current role as Sales Project Coordinator. In this role, he communicates directly with PGC customers to ensure that they have the best experience possible. He’s even traveled abroad to China, Mexico, and Australia in order to best serve customers’ needs. In his free time, Adam enjoys spending time outdoors, traveling and exploring the local breweries and restaurants available in the area.
