George Timinskas

Owner and Principal Engineer

Born and raised in Scranton, Pennsylvania, George’s leadership began at an early age as a young Cadet Squadron Commander in the Civil Air Patrol.  Enlisting in the US Air Force, George became an honor graduate of the Air Training Command, which led to his appointment as Lead Recovery Crew Chief on a flight of B-47 SAC Bombers loaded with nukes during the Cold War.  After a distinguished Air Force career, George returned to PA, becoming a Registered Land Surveyor and shortly thereafter earned his degree in Civil Engineering from Penn State University. 

George and his young family moved West to Las Vegas in 1980 to begin his adventure as a Senior Facilities Engineer at the US Department of Energy’s Nevada Atomic Test Site.  During this historic period, George was selected to be the Senior Engineer for the Augmented Test Program, widely regarded as critical to America’s success in bringing an end to the Cold War.  George’s leadership and expertise on this and a wide array of other top-secret projects ultimately led to his nomination as Facilities Engineer of Area 51.  Yes, THE Area 51. George moved to Mesquite in 1997 and founded TEC Engineering, a parent company.  He brings his over 50 years of engineering expertise, critical insight, and immense breadth of competencies across innumerable fields to bear upon each and every project TEC 3 Engineering takes on.
