Father Timothy Sas

Father Tim was born on April 16, 1973 in the city of Simeria, Romania as the eldest of five children in the family of an Orthodox Christian priest. Due to increased persecution at the hands of the Communist regime, his parents fled Romania in July 1988 and ended up in a refugee camp in Sweden. Fr Tim and his siblings were reunited with them in February 1989. In January 1990 Fr. Tim’s family moved to Vancouver, BC, Canada where his father became the pastor at one of the Romanian Orthodox Churches.

Fr. Tim graduated from St. Andrew’s Seminary, Winnipeg, in 1998. In August of that same year, Fr. Tim moved to Winona, Minnesota, to pursue a master’s degree at St. Mary’s University. On the feast of Transfiguration, August 6, Fr. Tim was ordained to the diaconate and on Sunday, August 8 to the priesthood by the hand of the late Archbishop Victorin at St. Stephen Church (ROA) in South St. Paul, Minnesota.

In March 2002, Fr. Tim and family joined our community of St. Mary’s and was an assistant priest to Fr. Harry Pappas. He was subsequently assigned to Twelve Holy Apostles Church in Duluth in September 2004. In January 2022, Fr. Tim returned to St. Mary’s as Proistamenos.
