He began his career immersed in the fast-paced world of healthcare strategy, where he learned how small operational shifts could transform entire organizations. From optimizing virtual care delivery to redesigning triage systems, Sebastian helped healthcare networks and private equity groups uncover opportunities for growth and scalability. His work wasn’t just about process — it was about people, systems, and creating the kind of structure that allows innovation to thrive. That same analytical mindset and eye for value later guided him into the world of commercial real estate. Today, as an advisor with ONE Sotheby’s International Realty, Sebastian manages and markets one of Miami-Dade’s most extensive portfolios — more than 100 active listings spanning office, retail, industrial, and development spaces. He crafts strategies that don’t just fill vacancies, but position properties to attract the right tenants and investors, helping owners realize the full potential of their assets. Whether he’s advising on a healthcare expansion or structuring a real estate deal, Sebastian approaches every project with the same focus: to identify opportunity, refine execution, and deliver lasting value. His journey reflects a commitment to strategy and adaptability — two traits that continue to define his work across industries.
