About Tierney

We are a fully-integrated agency that operates offices in Philadelphia, New York City and Harrisburg, PA. We are proud of our history and are as passionate today about our growth as we were 76 years ago. We have successfully grown our practice by staying ahead of what consumers demand and offering inspired brand solutions. Some of our clients include Yuengling, AmerisourceBergen, Independence Blue Cross, Choice Hotels, PECO, Xfinity (Comcast) and ShopRunner.

Our agency philosophy is to inspire curiosity. To do that, we harness the power of why. Always asking, always searching, and always driving to what’s next. Our curiosity has a purpose. It powers our creativity and allows us to tell a brand’s story in a unique and compelling way. We achieve this through three core values: perspective, openness and passion.
