Sergio Rok

Rok has taken the Aventura-based commercial investment, development, management and lending firm founded by his late father from a downtown Miami landlord to developer of oceanfront luxury hotels and condos. 

The trajectory started in the 1970s and 1980s, as his Cuban exile father, Natan Rok, bought single-tenant buildings, often boosting profits by dividing them into multiple units. The younger Rok has set off on a new course with his planned $3 billion waterfront Bahia Mar Fort Lauderdale project, in partnership with Tate Capital and Related Group. The first phase will have three St. Regis-branded towers with 160 condos, 79 condo-hotel units and 197 hotel keys. The project, nearly a decade in the making, has progressed with fits and starts caused by now-settled litigation. 

This is not the first time Rok has partnered with Tate and Related. The trio joined to buy distressed debt and assets during the Great Recession, including Omni International Mall, generally selling them off at a profit over time. The shift to luxe development under Sergio’s leadership has seen the firm pass the baton of largest downtown Miami landlord to Moishe Mana, selling him several neighborhood buildings. 

Sergio also has shown a willingness to sue. He was among the Presidential Estates homeowners who sued over BH Group’s plan for 134 homes on the golf course surrounding the HOA, leading to a settlement allowing 103 homes. In Aventura, Rok Lending foreclosed on a development site in 2025.
