We build a solid foundation of trust and expertise.


LEFKO Construction evolved out of three generations of builders and entrepreneurs.  The company began operations in 2004, when brothers David Lefkovits and Marc Lefkovits, both Georgia Tech engineers, decided to team up with their father Tomas Lefkovits. Tomas had previously run a large and successful construction company in his native Venezuela.

LEFKO Construction’s first project was in the City of East Point, near Atlanta, after which the company quickly won accolades and more projects. Since then, the company has continued to grow by being a trusted business partner to numerous private and public entities in the Greater Atlanta Region.

Today, LEFKO’s core group of professionals safeguard the quality and process of each project, executing each project from start to finish with the goal to always exceed clients’ expectations.

The key ingredients of LEFKO’s ongoing success are professionalism, work ethic and strong values.  From Tomas and Marc on down, there is a commitment to transparent communication, outstanding customer service, as well as extensive construction expertise and a unique ability
to get things done.



We build long-lasting relationships with our clients and partners.



Our team of professionals gets the job done right – on time and on budget.

Georgia Hispanic Construction Association history is intimately tied to LEFKO’s own story.  The organization was founded in 2012 with the objective of bringing together Hispanic construction companies in Georgia to aid their business development, networking and education.

Tomas was a founding member, Treasurer and Board member, while Marc has served as a Board member since 2013 and as GHCA’s President for 2019 and 2020.

The Lefkovits’ support for innovation, education and establishing a business support system for the Hispanic construction community found a natural home in GHCA and underlies their belief in giving back to the community and fostering entrepreneurship.



Our team of project managers and superintendents, comprised of civil engineers and architects, is uniquely qualified to handle all your construction needs.  Our education, experience and industry contacts set us apart from others in the industry.  Moreover, our open, collaborative working environment allows us to build long-standing relationships and deliver enduring value for our clients.
