Singsaas started his career in 1978 as a substitute minister at
Høybråten Church in Oslo, but the same year he was assigned to the permanent position of
chaplain for the
Diocese of Nidaros, a job he held until 1991. From 1991 until 2004, he was the resident chaplain at the
Nidaros Cathedral. From 2004 until 2008, he was the
Dean of the
Byåsen prosti (
deanery) in
Trondheim Municipality. In 2008, the bishop of Nidaros,
Finn Wagle retired and Singsaas was one of several nominees for that seat, and was consistently favored to win the appointment. He was appointed Bishop of the
Diocese of Nidaros by the
Norwegian Council of State on 27 June 2008. He was
consecrated as Bishop on 14 December 2008. ==References==
