About us

We’re authors. We’re artists. We’re visionaries. 

At GMA, it is our passion and expertise to amplify your voice as a visionary creator. Our clients are looking for more than a traditional talent agency; they’re looking for a partner to help them brainstorm, strategize and execute. 

For thought leaders, GMA helps visionary creators, authors, keynote speakers, and entertainers such as yourself bring ideas to life through published works and transformative experiences. 

GMA also thrives by connecting inspired and driven organizations to engage with today’s most extraordinary talents. If you’re searching for a curated collection of keynote speakers, authors, entertainers, or storytellers, you’re in the right place.

We’re ready to put pen to paper, so come on in, sit next to the fire, grab a cup of tea (or other cozy beverage), and let's get to work.
