Growing up on a farm in central Minnesota, Conley Janssen learned that welding was a fact of life for repair and modification of the farm equipment. He first taught himself to weld at around 10 years old. After his service in the Marines he decided to get some "formal" schooling in the welding trade. In 1996 he attended Dunwoody Institute for welding in Minneapolis Minnesota. He graduated in the top of his class and then stayed on to take advanced night school classes and assist in teaching the basic night school. Conley also has a strong back ground in electro-mechanics, with this and experience he found work at Minneapolis Oxygen welding supply company as a welder repair, service and set-up technician. This job included set up of some very complex welding systems and instructing the owners how to use them. After working here for 2 years he started Janssen Fabricating, a broad based fabrication business to work with everything from emergency vehicle modification and build-up to large shop welding projects.

Conley also has worked for Motorola as an installer and Emergency Vehicle modifer. He is experienced in the building of emergency vehicle lighting, sound, and communications systems. He also has experience with the repair and modifcation of the GM 6.5 Turbo diesel engine. One of the things that JFE offers for sale is a 6.5 injector socket.
