A Friendly word from The Queen herself 


You’re here and you’re now. So let’s get you in the know in this new social interactive dawn of media and TV. I dare YOU to join me, Marki Costello, on this game-changing journey to becoming a successful, working on-camera personality.

We are at the dawn of a new media era where broadcast and digital are merging. Broadcast outlets are investing tons of resources into their dot com’s as well as their TV channels. Double the outreach equals double the available work, BUT also double the chances for the viewer to get the content they need. With that being said, it’s becoming increasingly difficult to engage your audience. The mistake that many of today’s on-camera hosts make is modeling the old way of hosting. But generically pretty, polished, perfect hosts are OUT, and personality-driven delivery is IN. Your job as an on-camera host/personality is to create a compelling need, through your personality and point of view, for viewers to get content from you.

They say insanity is doing the same thing over and over again and expecting different results. So I’ve made it my personal and professional mission to continuously deliver new information. I provide the necessary tools and resources to help you navigate, thrive and survive in this ever-changing business, and I will help you discover, define and deliver your brand in a way that nobody else will. I know exactly what buyers, I know what the trends are, what’s in and what’s out. The biggest mistake you can make as talent would be to seek information from an out-of-work host turned host coach, who ultimately has no idea what buyers want and need. But I know this business like the back of my hand. I am in the trenches and I am in the know.

 So, I’ve already dared you to join me. Now for the truth – and that is, that everybody can succeed in this genre because you don’t have to have a lick of talent to be YOU
