Dennis Fahringer began in photography in 1963, started teaching photography in 1970, and became a professional photographer in 1972. He ran a freelance photo business for three years before beginning his career as a missions photographer in 1974 in Washington, DC. (That was with the now defunct Christian Service Corps.) He began serving on Youth With A Mission (YWAM) staff in 1977.

He serves as non-salaried full-time volunteer staff at the University of the Nations - Kona (UofN-Kona). The UofN is the training part of the larger Christian mission organization of YWAM. This is a unique university, with 785 locations of UofN in 163 nations, teaching in 95 languages. Dennis leads the intensive School of Photography I (SOP I) and School of Photography II (SOP II) and their internships. Each of these are 12 week, 12 credit university courses in the UofN.

Dennis pioneered the SOP I in the Netherlands. His January 2020 SOP I was his 47th photo school so far with the UofN, thanks to the Lord.

God has taken Dennis and his cameras to 51 nations so far.
