Marketing Programs That Deliver Results

Forty-five years ago, we started creating content. Today, we deliver award-winning marketing strategies and programs for more than 50 companies, healthcare organizations, and professional associations across the country. Whether your content is delivered via print, digital, video, or social channels, a good program starts with a sound strategy and improves through measurable results.

What Sets Us Apart?


In 1969, the buzzword “content marketing” didn’t exist, but the goal of creating great communications programs did. More than four decades later, we’re still delivering.


We have one of the lowest turnover rates of any marketing agency. People join GLC and stay. That solid consistency is good for our business but even better for our clients.


Clients don’t just hire us; they partner with us. Transparency, accountability, flexibility, and relationship-building are key to our collective success. After all, we’re a team.


We believe in continuous improvement. That means always analyzing data and metrics to ensure we deliver brand awareness, engagement, loyalty, impact, and revenue.

Our Services

Strategic, Original, Actionable, Measurable


A robust strategy fully analyzes the who, what, when, where, and why of your entire communications plan—so you can move forward with an efficient roadmap toward measurable results.


We’re expert storytellers and provide branded content developed specifically for you and your audience. Our content is never repurposed; always authentic, original, and actionable.


We know print is as powerful as ever. Branded magazines, journals, newsletters, marketing collateral, brochures, and books are essential ingredients to any robust content strategy.


Websites, blogs, videos, social media marketing strategies, e-newsletter programs, and marketing automation. These are just a few of the measurable digital solutions we offer.


Our award-winning design team knows how to bring a brand to life, creating imagery and layouts for websites, magazines, apps, annual reports, and advertisements. We can do it all.


We all know content is king, but distribution is queen. Making sure your message reaches its intended audience—and that they engage with it—is paramount to your success and to ours.
