Inside the sold-out charity event that pulled in young Wall Streeters on Thursday night

Young Wall Streeters headed to New York City dance club Marquee on Thursday night, decked out in sparkling cocktail dresses and dapper suits for the sixth annual Toast to Wishes charity event organized by Make-a-Wish New York's under-40 board.

The event, which has brought in $1.5 million over the past six years, helps grant the wishes of children diagnosed with life-threatening medical conditions.

"We felt like there was a void in the market, so to speak, of really fun - truly fun - charity events that supported great causes," Zach Coopersmith, the 30-year-old organizer for the event, told Business Insider. Coopersmith is a cofounder of Lending Ridge Capital. "For me, the impact that Make-A-Wish has on kids and their families dealt such a tough hand is unmatched, unparalleled," he told last year's attendees.

With an open bar, a DJ, and plenty of hors d'oeuvres, the gathering attracts 650 people and features silent auctions and raffles. Tickets cost $185 for general admission; the event sold out.
