General Gorenc was born in Ljubljana, Yugoslavia, present day Slovenia. Frank and his older brother, Stanley immigrated with their parents to the United States from the former Yugoslavia in 1962 when they were 8 and 4. After arriving in America, their father worked as a tailor, and their mother served as a factory machine operator. General Gorenc said that he was required to go to summer school each year simply because the opportunity for education existed and was available. “We didn’t know the language,” Frank said. “We didn’t know the culture, and we came to learn (that) the United States is truly a land of opportunity.” Frank went to visit his older brother, then a freshman cadet, during Parents’ Weekend at the U.S. Air Force Academy, and there he developed his first interest in the Air Force. “As a freshman in high school walking on the academy campus, you couldn’t help but be inspired,” the younger brother said. Coming from a lower-middle-class background, the opportunities seemed boundless.
As a Brigadier General, Gorenc was the Director of Operational Plans and Joint Matters, Deputy Chief of Staff for Air, Space and Information Operations, Plans and Requirements at the Headquarters U.S. Air Force, Washington, DC. He was responsible for developing and integrating operational strategies, organization concepts, policies and plans supporting aerospace power employment. The General's six divisions orchestrated Air Force participation in joint and regional war and mobilization planning communities, as well as operator and warfighter talks with allies and sister services. He oversaw the Air Force's concept of operations development as well as its interface with Joint Staff and National Security Council issues. Prior to assuming this position, he was Commander, 332nd Air Expeditionary Wing, Balad Air Base, Iraq.
General Gorenc served as the Commander, Third Air Force, Ramstein Air Base, Germany. As the U.S. Air Forces in Europe component numbered air force for U.S. European Command, 3rd Air Force supports the USAFE and EUCOM commanders both at the operational and tactical level directing all USAFE forces engaged in contingency and wartime operations in the EUCOM area of responsibility. Third Air Force includes the headquarters Air Force forces staff, a multidisciplinary, professional cadre responsible for planning, deploying, employing, sustaining and redeploying Air Force forces as the supported and supporting air component of USAFE to EUCOM. Other 3rd Air Force units include the 603rd Air and Space Operations Center, 10 USAFE wings and two stand-alone groups. Gorenc relinquished command of 3rd Air Force to Lt. Gen. Craig A.
