Our Team

James Valiensi, PE, CEM

Clara McCarthy, PE
James has worked in the operations, maintenance, installation and design of HVAC system since 1985. Unlike most engineers, he started his career in owner-side facilities, gaining practical experience repairing and putting together HVAC systems and collaborating with design professionals. His hands-on experience combined with an engineering education is a rare combination and allows him to solve problems where other engineers cannot. Whether it’s a simple project with rooftop unit replacements or a complex central plant design, James’ approach results in cost effective solutions that work, are easily buildable, and simply maintainable.
Clara brings incredible energy and enthusiasm to CJ Enterprise. Her talent and skills are far beyond her limited experience as an engineer. Clara loves to solve problems and is persistent in finding solutions that best serve the client’s needs. She can visualize what the project will entail and what the finished product will look like because of her extensive time surveying mechanical systems in the field. Her excellent written and spoken communications turn complex ideas into easy-to-understand concepts. Clara brings a fresh and bold perspective to a mature industry and challenges old ideas to provide more modern designs.
