Golley Slater has been creating memorable ideas for a long time. We first opened our doors in 1957. Shortly after, we aired the first live to air TV ad. But that’s where the history lesson ends.

All of our work and strategic expertise focuses on tomorrow, not yesterday. We create beautifully effective communications based on what people really want, not what they say they want. We’re proud to be based in Wales, but our reputation for beautifully effective, award-winning campaigns pays no attention to geographical borders.

In recent years our advertising team has been recognised on the international stage, winning a Cannes Gold Lion to add to Creative Circle awards among others. Our PR team continues to win Welsh and UK awards, including the CIPR’s Consultancy Team of the Year, for campaigns promoting many of Wales’ best known public and private sector organisations. Our growing media business now represents the majority of Wales’ public sector bodies.
