Mayi de la Vega, Founder and CEO, ONE Sotheby’s International Realty

Cuban American real estate powerhouse, Mayi de la Vega is the Founder and CEO of ONE Sotheby’s International Realty (ONE SIR), a Sotheby’s Auction House affiliate and leading luxury brokerage firm in South Florida, that’s recognized in the Sotheby’s International Realty international network as the 5th highest producing affiliate based on average sales pricing. As a true visionary, de la Vega founded the luxury brokerage firm back in 2008 during the depths of the country’s worst economic crash with one office and 30 agents, which today has flourished to 14 offices and more than 750 agents.

Alongside her son, Daniel de la Vega, the current president of ONE SIR, and Mayi’s leadership, ONE SIR’s development division set the precedent in the luxury market with 18 revered, luxury pre-construction exclusive developments in Miami-Dade and Broward, holding the majority market share of luxury condominiums above the million-dollar mark in their portfolio, which account for more than $4 billion worth of real estate inventory.

De la Vega prides herself in building a sustainable lifestyle, network and community for her clientele and staff. ONE SIR is recognized as the true voice of luxury through de la Vega’s achievements of maximizing the prestigious reputation of the historic Sotheby’s Auction House, challenging the status quo within the Sotheby’s International Realty network with award-winning marketing methods, publishing of ONE LIFE magazine and her induction into the network’s elite Braintrust Consortium.

The woman entrepreneur, philanthropist, real estate expert and avid art collector dedicates a lot of her time traveling the globe, serving as the brand ambassador for ONE SIR, while marketing Miami as an international cultural mecca.

Aside from serving as CEO of her company in the luxury real estate industry, she also dedicates her time to the local community through charitable, philanthropic organizations and educational programs both domestic and international. De la Vega serves on the chair committee for the Cisneros Fontanals Art Foundation and United Way of Miami Dade. She served on the Chair Committee for Nicklaus Children’s Hospital, The Board of Trustees for FIU, and as a “Guardian Angel” for Jackson Memorial.

She currently resides in Miami Beach, Florida.

My story begins like many Miamians. My family fled Cuba when I was three years old, along with hundreds of thousands of other exiles in hopes of a better life and future. I don’t remember much about my homeland, but I have vivid memories of acclimating to our new lives in America. My family settled in a small apartment, and as a child I would tag along with my mother as she cleaned offices. I remember we only had enough money to take the bus one way from the grocery store and my father would sing the whole way home to keep us entertained. A professional baseball umpire in his former life, he had to start over with nothing.
