Meet the jet-setting architect who designed some of the world's most expensive casinos, including the ultra-famous Cosmopolitan in Las Vegas

Sometimes the biggest power players are the ones who stay behind the scenes. 

Architect Brad Friemutter may not be a household name, but together with the firm he founded in 1992, the Friedmutter Group, he has provided the design muscle behind some of the most expensive integrated resorts and casinos in the world: the Cosmopolitan in Las Vegas, Harrah's in Atlantic City, and the recently opened Studio City in Macau, just to name a few.

His projects are often worth billions - Studio City, for example, publishes at $3.2 billion - and the resort owners he works with are usually billionaires. 

"They know all of the nicest things in the world. They've been to the nicest hotels, and restaurants, and places in the world," Friedmutter told Business Insider. "We as designers have to have seen those places as well, so that we understand."

We recently caught up with Friedmutter and his wife Kimberly to hear a bit more about their jet-setting lifestyle.
