His first assignment following pilot training was flying B17s at Eglin AFB, FL. In 1955, he was selected to be an Air Force Academy (USAFA) Air Training Officer (ATO). During this tour, he met and married Helen Jones. In January 1958, Herman moved to March AFB, CA, to fly the B47 with a follow-on tour to Dyess AFB, Texas. In 1963, Herman returned to the USAFA to teach Economics. One year later, he was selected to attend Harvard University
, pursuing a PhD in Economics. Upon completion, Herman again returned to USAFA to teach. In 1969, Herman was deployed to Vietnam. After completing his tour in 1970, he again returned to the Air Force Academy to teach. In 1971 Herman was transferred to Hickam AFB to serve at HQ Pacific AF.

Retiring from the AF in 1979, Herman moved to Seattle, WA, to work for Boeing. In 1986, he and Helen returned to the city they loved at the foothills of the Rockies.
