Professional Summary

As Executive Director - Office Services, I currently handle leasing and sales of office buildings and land throughout Miami-Dade County as well as representing major tenants in the market place.  Considered a veteran in the commercial real estate industry, my career spans more than four decades and has connected me with some of the brightest and best in South Florida, fueling my success. In the last five years, I have leased more than 1.5 million square feet of commercial space.

Prior to Colliers International, I was the Vice President of Flagler Real Estate Services for 19 years. I was also the owner and Chief Executive of Summa Properties, a commercial real estate brokerage, leasing and management firm.  From 1983 to 1991, as the partner in charge of Tishman Speyer Properties’ Miami office, I was responsible for development of the Brickell Square project, Westside Corporate Center and the Federal Law Enforcement Building, and leasing and management of Airport Corporate Center, the SunTrust Building, One Brickell Square and Westland Executive Center.

In the years preceding my Tishman partnership, I managed the CB Richard Ellis Miami Office, supervising more than 30 brokers and support staff, and before that I served as general manager of the Grove Isle development.
