About Us

Tri-Group Construction has been in business as a general contractor since August 1, 2001 performing solely public works projects within the limits of San Diego County.

Our team is lead by the Assi brothers. Ghassan Assi, President, has over 30+ years experience as a field superintendent, and Hani Assi, Vice President, has spent his 20 years with Tri-Group as it's Project Manager and Chief Estimator, and served as a Resident Engineer for the City of San Diego for over a decade prior.

Each and everyone of our crew has worked within the public works construction industry for several years and are proud as a company to continue to employ many crew that have been around since Tri-Group's infancy.

Tri-Group employs over 25 field crew, ranging from laborers, cement masons, carpenters, bricklayers, operating engineers and site-superintendents. Of course, our field crew is backed by its tremendous office staff consisting of estimators, project managers, project coordinators, accountants, and labor compliance officers.
