In 1969, four decades after our founding and in response to the growing need for skilled workers in the area, the Washington Institute of Technology was founded and licensed by the Pennsylvania Department of Education, Private Licensed Trade Schools Board. The Institute started with three electronics students, and in the years to come it would offer quality training in electronics; drafting; and heating, ventilation, and air conditioning. In 1979, Penn Commercial was incorporated into the Commonwealth of Pennsylvania. The popularity of our offerings and quality of our programs led to significant growth over the years. In 2001, we purchased a building in the Oak Spring Plaza in Washington, Pennsylvania--our current location--and immediately began renovating the 64,000-square-foot facility. The renovated building opened later that same year, offering current technology, various labs and classrooms, a student services center, and ample (free) parking.
