Veteran South Florida broker Mark Zilbert has joined ONE Sotheby’s International Realty. 

Zilbert will launch The Zilbert Group at ONE Sotheby’s Miami Beach office and focus on luxury residential and preconstruction sales across South Florida. 

Zilbert entered real estate in 2003. Since then, he has facilitated more than $5 billion in transactions, including at luxury Miami condominiums The Continuum, Surf Club Four Seasons, Oceana Bal Harbour and Acqualina Estates. 

He founded Zilbert Realty Group, which rebranded as Zilbert three years ago with a focus on AI-powered lead generation. The Zilbert website will continue to operate as a referral source.  

At ONE Sotheby’s, Zilbert plans to expand The Zilbert Group across major Florida markets, including Miami-Dade, Palm Beach and Indian River counties and markets new to the brokerage.  

“ONE Sotheby’s International Realty is proud to align with a forward-thinking professional like Mark, who is a leading light in our industry,” ONE Sotheby’s President Daniel de la Vega said in a press release. “Welcoming him into the ONE Sotheby’s family is a testament to our commitment to fostering talent of the highest caliber. Backed by our cutting-edge technology, agent-centric tools and unparalleled access — Mark will further elevate his brand and take his business global.” 

“ONE Sotheby’s International Realty offers the global brand recognition and platform to extend my reach on an international scale,” Zilbert added.  “With this move, I gain a brand with a local footprint and worldwide presence that I can see represented no matter where I travel, here or around the world.”
