Framingham-based clean energy infrastructure company Ameresco has named two new co-presidents and an inaugural chief operating officer in an executive restructuring blitz.
Ameresco CEO George Sakellaris has handed over his presidential role to executives Nicole Bulgarino and Lou Maltezos. The two will serve as the company’s new co-presidents starting Wednesday, according to a Tuesday filing with the U.S. Securities and Exchange Commission.
Sakellaris will continue in his roles as CEO and chairman of the company of 1,601 worldwide employees and $2 billion in annual revenue.
Bulgarino and Maltezos are veteran Ameresco employees, having both joined the firm in 2004.
Bulgarino’s promotion expands on her most recent role as president of federal solutions and utility infrastructure. In her new role, she will lead initiatives supporting data centers and large energy infrastructure projects and the firm’s federal solutions business, the company announced Tuesday.
Maltezos’s promotion extends his most recent role as the firm’s president of Central & Western USA, Canada regions. He will now manage the company’s non‑federal project organization and continue to lead Ameresco Canada.
Additionally, the firm has named Peter Christakis as its first COO, promoting him from his former role as its president of East USA, Greece and project risk. In his new capacity, Christakis will continue to oversee the company’s procurement initiatives, U.S. solar and battery operations, and European operations. He has worked at Ameresco since its inception in 2000.
Founded in 2000, Ameresco creates energy infrastructure solutions to reduce costs and increase decarbonization for educational and health care institutions, housing authorities, data centers, and municipalities, according to the company’s website.
With 157 local employees as of 2024, Ameresco is Central Massachusetts’ fourth-largest clean energy company, according to WBJ’s Research Department.
