Anthony Closson

Colossal Contracting, LLC is a company built on military core values, experience, skill, and dedication to excellence in all they do. Colossal is comprised of former military professionals who have turned their dreams into reality. CEO Anthony Closson envisioned this opportunity while deployed in Iraq as a communications specialist. Closson’s experiences in Iraq and working stateside at Joint Base Andrews taught him the crucial relationship between government employees and civilian contractors.

Mr. Closson’s final assignment at Joint Base Andrews as an IT Project Manager cemented the foundation of his dream to start Colossal Contracting LLC. He then called on his former wingmen and family to join in his quest. That is why Colossal is proud to be “BUILT ON MILITARY CORE VALUES.”

Colossal understands the importance of taking care of their customers. Through dedication to customer service and a commitment to excellence Colossal continues to make a name for itself in the IT industry. Owner Anthony Closson attributes the early success of Colossal to the “Can Do” attitude of his entire team at Colossal Contracting, LLC.
