Joseph Mancino

Founder & CEO

Joe Mancino is the CEO & Founder of GreenSigns. As a 35+ year billboard veteran, Mancino led multiple outdoor advertising companies to success before establishing GreenSigns. 


Joe immigrated to the United States from Sicily when he was seven years old. The son of industrious and venturesome parents, he was determined to make the most out of his family’s journey from a small farming town to the city of Chicago. 


While building his OOH career, Joe ran for mayor of Hawthorn Woods – a suburb 25 miles northwest of Chicago. During his 12-year term, he became involved with multiple environmental initiatives that impacted the entire Chicago region. He also led regional boards that addressed transportation, sustainability, and housing in the greater Chicagoland area.


All this inspired him to build GreenSigns – an eco-friendly billboard company that gives environmentally-conscious clients a choice to fully live and operate in alignment with their values. 

Joe rarely sits still. As an accomplished amateur boxer, private pilot, and avid biker, he is always on the go. You can get in touch with him at
