At GH, we prefer to have your back instead of being out in front.

Staying invisible to your competition – that’s our surprise move. The win that seems to come out of nowhere. We admit we are obsessed with being your undetectable secret weapon.

Only with our clients’ permission do we provide referrals for potential clients.


Our clients are an impressive mix of corporations, family-owned businesses, non-profit organizations, and individuals. From Philadelphia to London, they come from the finance, healthcare, biotech, education, consumer service, IT, agriculture, and social service industries. We also have a few famous authors and politicians as clients – and that is always fun!

They care deeply about building their brands and staying connected with their clients, consumers and online audience. They are passionate about what they do, and recognize our work gives them a distinct lead on their competition.


We are multi-disciplinary. Our team of public relations professionals, sociologists, digital marketing strategists, and creative content designers capture the attention of our clients’ target audience and influence their actions.
