Upon completion of an extensive survey of the area in September 1961, the Northwest District of our Lutheran Church-Missouri Synod resolved to establish a mission in this rapidly growing community. The “Mother Church” of St. Timothy was St. Matthews in Edmonds. 

Rev. F. Arthur Schweim, the pastor of Mt. Zion, Mountlake Terrace, was selected to serve as pastor of St. Timothy.  This meant he would have to serve two churches on Sunday mornings.  This he did by having the St Timothy service at 9:00 AM. The first services were held at 9:00 AM on May 12, 1963, in the Beverly Elementary School Multi-Purpose Room with 25 present. 

In March of 1962, 4.8 acres were purchased on the corner of 164th SW and 52nd West, and an architect, Mr. Robert Chervenak of Seattle, was appointed.  Preliminary drawings of the proposed $75,000 church and educational unit were then completed and approved. In August of 1963, ground was broken for the church building. The first worship service in the new sanctuary was held on Ash Wednesday, February 12th, 1964.  The dedication was on June 14th, 1964.  Saint Timothy Lutheran was officially affiliated with the Lutheran Church-Missouri Synod in June 1966.

In March of 1970 ground was broken for a new education building which was dedicated in September. In 2007 a narthex was completed that created a new entry and joined the sanctuary and education buildings.
