...and Top Dogs

As Onello tells it, a certain type of person seems to be drawn to boxing. "The guy who takes the risk but also wants the reward. These are guys who want to be top dog, and a lot of them are."

While Onello has no trouble relating to his clients, sometimes when they talk about Silicon Valley, he admits he tunes out. "That tech world is almost like a foreign language, like they're speaking Chinese," he says. "I started playing with a computer at age 35. They probably did at 5."
