Marcos Macías, Vice President
Marcos Macías is a commercial real estate broker based in Miami, specializing in sales and leasing across South Florida. Originally from Cuba, Marcos moved to Miami in 2017 and began his real estate career in 2019, bringing a strong work ethic, multicultural perspective, and client-first mindset to every transaction. He is fluent in both English and Spanish.

He approaches real estate as a long-term wealth strategy, advising investors as a trusted partner and helping them identify, acquire, and manage income-producing properties.
