Shamrock’s Management staff has over 150 years combined experience in the Sign and Custom Lighting Industries. We have partnered with Pittsburgh Corporate Leaders in the Finance, Health Care, Professional Sports, Retail, Broadcast Media and Business Services Industries on a wide range of Signage projects.

We are proud of our part in creating one of the Country’s most beautiful skylines with our unique, custom high-wall signage which is often seen during nationally televised sporting events. We believe that Pittsburgh’s vibrant downtown skyline is a reflection of the pride that our corporate leaders feel in having chosen The City of Pittsburgh as their Corporate Headquarters.
