I got a haircut from the elite New York City barber who cuts Jack Dorsey's hair - and it was incredible

Dzenad Bicic - better known as Geno - is one of New York's most talented and respected barbers. But if you talk to him, you might think he's also an amateur philosopher or village elder, dispensing hard-earned wisdom with the greatest of ease.

He has cut the hair of everyone from Twitter and Square CEO Jack Dorsey to actor Daniel Day-Lewis, but if you ask him how he became so successful, he'll respond with just one piece of advice.

"If you're patient, everything will come," Geno tells me as we sit in his barbershop on Greenwich Avenue in New York City's West Village. Looking around at everything he's built for himself, it's hard not to believe him.

We spoke with the Montenegrin owner, operator, and (still) full-time barber of Geno's Barberia to see what it takes to cut the hair of New York's elite. (Hint: it's a lot of skill and a super-positive attitude).
