Environmental Systems Co. promotes Mike Amedeo to President
WEST HARTFORD, Conn. – July 7, 2025 – Environmental Systems Co. (ESC), a Fidelity Building Services Group (Fidelity) company and leading provider of building technology solutions throughout Connecticut, is pleased to announce the promotion of Mike Amedeo to President.
Amedeo brings more than 30 years of experience in building systems—including HVAC, electrical, mechanical, building automation, and security—to his new role. As President, he will lead ESC’s strategic vision and operations with a strong focus on innovation, customer satisfaction, team development, and long-term business growth. A collaborative leader, Amedeo is committed to continuing ESC’s legacy of delivering high-performing building solutions and exceptional service.
“I’m honored to take on this new role and continue building on the strong foundation that has made ESC a leader in the industry,” says Amedeo. “It’s been a privilege to work alongside such a talented and dedicated team, and I look forward to guiding the company into its next chapter.”
Amedeo joined ESC in 2009 as the Energy Division Manager before being promoted to Vice President of Sales in 2019 and to Executive Vice President in 2021. In these roles, he oversaw the strategic direction and daily operations across multiple divisions, including Automation, Security, Fire/Life Safety, Energy Solutions, Audio Visual, and Mechanical Services.
Amedeo’s promotion follows the retirement of Mike Mullin, who has served as President of ESC with outstanding leadership, professionalism, and vision. Mullin joined ESC in 2011 and was instrumental in leading continuous improvement initiatives and strengthening the company’s operational and financial performance. Since ESC became part of Fidelity in 2023, Mullin played a key role in aligning the company with Fidelity’s long-term goals and values.
“Mike Mullin has been a mentor and a trusted leader throughout his time at ESC,” says Carmine Mistichelli, COO/Partner at Fidelity Building Services Group. “We are incredibly grateful for his many contributions and wish him all the best in his well-earned retirement. At the same time, we are confident that under Mike Amedeo’s leadership, ESC will continue to thrive and deliver proactive, world-class results for our clients and Team Members.”
