About G Adams Group
Federal experience built from the ground up.
Founded by Selina Freytas in 2009, G Adams began its government-contracting journey through HUD’s Neighborhood Stabilization Program. That early work established a lasting commitment to public-sector performance, small-business participation, and disciplined project delivery.
Since then, G Adams has procured more than $50 million in construction-related materials and services and supported work for the Department of the Navy, National Guard, Department of the Air Force, U.S. Army Corps of Engineers, General Services Administration, Drug Enforcement Administration, United States Postal Service, and public-sector clients.
Today, G Adams Group applies that experience through General Construction, Construction Management, Owner's Representative Services, and a specialized Roofing Division.
Federal Experience
Experienced where performance matters most.
G Adams Group brings federal construction experience supporting work associated with GSA, the U.S. Air Force, the U.S. Navy and the U.S. Army Corps of Engineers.
We understand the planning, communication, documentation, and field coordination required to deliver work in occupied and mission-sensitive environments.
