Singsaas was born and baptized in Hølonda Municipality, Norway and grew up in Buvika and Melhus.

He was ordained as a minister in Melhus Church on 8 January 1978, with Bishop Tord Godal officiating.

[3] 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.
