Dr. Danielle Eve Greenman and Stephen Thomas Gellert were introduced through two dating apps — in November 2016 through the League, and then eight months later on Hinge.

“Oh hey, I remember you,” she said she messaged after swiping right on Hinge, and noticing his last name was the same as her father’s longtime investment partner and family friend. “Are you by any chance related to George Gellert?”

“George Gellert is my uncle,” he said, but their dialogue didn’t gain traction and soon fizzled.

A couple of weeks later, after he showed his uncle a photo of her on his phone at his cousin’s graduation at Cornell, he immediately recognized her, and stepped in.

“She is a really smart girl from a nice family,” he recalled his uncle saying.

“George is not a man who waits for things,” said Dr. Greenman, with a laugh, and the next thing she knew her mother told her: “George Gellert said you matched with his nephew. At least go on one date with him.”
