Team Principles

Roberto LaRocca

Roberto LaRocca, joined his father’s well established construction firm,  LaRoccaGroup in the 80’s and convinced his father to expand their vision to the real estate market and to get into other fields like office buildings, middle income housing projects, luxury apartments, luxury homes, hotels, etc. While developing different projects, they still invested time and resources looking for new construction technologies and started to develop their own construction system using panels.

Roberto, a Mechanical Engineer from Universidad Simon Bolivar and MBA from Instituto de Estudios Superiores de Administración (IESA) has carried all this technology and construction knowledge to Global Sigma Tech, and the legacy continues with his son Robert.

Leonard Albanese

Leonard Albanese has a family building legacy, for three decades, he has established an unparalleled reputation as a master builder of custom homes and outstanding communities. A licensed Building Contractor and Real Estate Broker with a degree in Business, Leonard has deep roots in the construction business.
