One Thousand Museum

One Thousand Museum, South Florida’s most prestigious new residential tower is redefining Miami’s skyline. This infusion of Art, Architecture & Design comes from the prolific imagination of Pritzker Prize Winning Architect Zaha Hadid. Over the past 30 years, Zaha Hadid has become internationally renowned for her designs of sensuous, soaring buildings that push the limits of innovation and blur the lines between art and architecture. Located at 1000 Biscayne Boulevard on a coveted property overlooking Museum Park and Biscayne Bay, One Thousand Museum will be Zaha Hadid’s first residential skyscraper in the Western Hemisphere. Rising to more than 60 stories, it will be comprised solely of half- and full-floor residences. Museum Park (formerly known as Bicentennial Park), the home of the Peréz Art Museum Miami and the Frost Museum of Science, is rapidly becoming one of Miami’s most prestigious cultural destinations. One Thousand Museum will offer iconic architecture, unprecedented amenities, stunning skyline and ocean views, and close proximity to Miami’s finest museums and performing arts institutions.

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.

 With Covid now, what’s your biggest challenge to balance personal life and running a business?

When the business environment started to shift in the wake of COVID-10, my focus went to the almost 1,000 ONE Sotheby’s International Realty agents that needed our team’s support. Our team’s every thought was about leveraging our technology and tools to keep our agents productive. We reinvented the business in a matter of weeks, boosting our virtual marketing efforts, launching seven new tech tools in less than 90 days. We promoted more marketing content than ever, and communicated on a daily basis with agents. I am so proud of our agent’s resilience during this time and I know this experience is makings us smarter and stronger for the future.
