These doormen guard the residences of New York's wealthiest residents

Many of New York's wealthiest people reside in multimillion-dollar condos on Park Avenue on the Upper East Side. There's 740 Park Avenue, where John D. Rockefeller, Blackstone founder Steve Schwarzman, and business tycoon David Koch have all lived. Just down the street at 730 Park Avenue, "billionaire bidding wars" have led to some sky-high home sales, including a penthouse that reportedly sold to hedge funder Daniel Benton for $39 million in 2012.

Guarding the entrance to these and other tony buildings along Park Avenue are the doormen who often live vastly different lives than those inside. A doorman's tasks can vary greatly, as they assist residents with everything from running errands, to loading up their cars, to calling cabs, and most importantly, providing security. As of 2014, unionized doormen in New York City made an average of $49,402 a year.

It was the unusual job of the doorman that photographer Sam Golanski was most interested in when he visited New York in 2015. He convinced them to pose briefly for his camera. "These guys are real people who need more attention. [They're] not pampered celebs wearing their Gucci bags and expensive watches," Golanski told Business Insider.
