Guided tours of Rockefeller Center don’t usually start with cocktails and bar snacks at the upscale French restaurant Le Rock. Nor do they typically end with pasta and a 30-layer chocolate cake at Jupiter, a popular Italian restaurant at the plaza in Midtown Manhattan.

But Beverly Nguyen, who led a group around Rockefeller Center on a recent Tuesday evening, is not your standard tour guide. For the group of marketing and public-relations executives from brands like Ralph Lauren, Cartier and Versace that she was showing around, Ms. Nguyen had arranged access to some “special spaces,” she said, while standing in front of Isamu Noguchi’s plaque sculpture “News,” carved into the facade of one of the plaza’s Art Deco-style buildings.

Though not a household name, Ms. Nguyen, 33, has, through a multi-hyphenate career, made a name for herself in various industries.

She is a fashion stylist and consultant who has worked with clothing brands like Kallmeyer and magazines like HommeGirls. She is the living editor at Family Style, a quarterly food and culture magazine. She is the owner of a home-goods store, Beverly’s, and became the first Asian American woman to have a shop at Rockefeller Center when she opened a Beverly’s pop-up in the plaza in 2021. (It has since moved to a permanent location on Orchard Street on the Lower East Side, not far from where Ms. Nguyen lives in Dimes Square, a neighborhood buzzing with young creative types.)

In 2022, Ms. Nguyen appeared on the cover of New York magazine’s annual “Reasons to Love New York” issue along with 71 other New Yorkers, the artist Alex Katz and the model Emily Ratajkowski among them.

This year, Ms. Nguyen was hired by Tishman Speyer, the real estate firm that owns Rockefeller Center, as an adviser on projects at the plaza involving brand activations with social media and hospitality components. She is among the latest in a string of local culture shapers — Le Rock’s chef-owners Lee Hanson and Riad Nasr; the J. Crew-executive-turned-reality-star Jenna Lyons; the Pebble Bar guys — tapped in recent years to burnish the image of the 85-year-old plaza.
