When he's not going up on a stage to talk, Dean Gemmell sits down and writes. In addition to stand-up material, he's co-authored a best-selling book about fitness training for curling, his favorite sport. He's also written a short guide that helps curlers improve a specific aspect of their game. And he somehow managed to sit in front of his laptop long enough to get a novel done. Finally, he writes all kinds of communications — traditional advertising, blog content, collateral, news releases — for a range of clients.  Thanks to spending more than 15 years as a copywriter and a creative director at agencies in New York City and the Midwest, he knows how to produce great work quickly and without drama.
