John and Louise Richey assumed the leadership of the new congregation and organized a Midwest training school. Their branch of Aimee’s L.I.F.E. school opened in the fall 1930 with 63 students registered for a 3 year night program. The new school was to be called the Midwest Preparatory Bible School, a branch of L.I.F.E. of Angelus Temple.  Students met in the upper room of the church for Bible classes.

According to Edith Waldvogel Blumhofer’s book Amiee Semple McPherson -Everybody’s Sister. John F. Richey and his wife Louise played a vital role in the church at 19th and Crocker.  Richey was a Kentucky farm boy who transplanted to California and received the baptism of the Holy Spirit at Angeles Temple, joined the choir, and signed on as a member of the watchtower prayer group that staffed Sister’s prayer tower on Sunday mornings from 4 AM until 6 PM. John enrolled in L. I. F. E. Bible School, and there he met Louise Hanson from Iowa. They married April 1925. They both taught and preached at the temple’s branch churches throughout the US. In May 1928, they excepted the call to Des Moines, Iowa. The two Foursquare Lighthouses, one located at 19th and Crocker and the other on the east side of Des Moines had been experiencing revival ever since Sister Aimee’s 10-day campaign and crusade held in March of 1927 at Good Park.

Out of 19th and Crocker the Foursquare planted churches in Des Moines, Cedar Rapids, Waterloo, Vinton, Burlington, Newton, Iowa Falls, Sheldon, Winterset, Forest City and Grinnell. In addition, churches were planted in St. Paul and Minneapolis, Minnesota . The annual report given in May 1932 stated the following for the 19th and Crocker Church: new conversions – 357, baptism by immersion – 108, new members added – 109, baptisms in the Holy Spirit – 44, church memberships – 425, Sunday School Enrollment – 525.

There was a shift of unhappiness with the changes in Aimee’s Lighthouse Association in 1928. Aimee decided to modify the arrangements in the Lighthouse Association by reserving to the Association the right to hold the property of local churches. Later in 1931, Aimee married Mr. Hutton. Some of her Iowa followers, the Richey’s among them, expressed strong misgivings about the marriage in principle. Aimee’s conduct was starting to over shadow her message. Her name had become a liability to their evangelistic cause.
