About Us


Each of our staff members are valuable assets to our church and its ministries. Without their dedication and willingness to serve, grow, and lead, our congregation would be lost indeed. Thank you, staff, for all your time and commitment to our ministries for Christ in this church and in the community.

ShelLu assists the Head of Staff and other office personnel with various projects, updating lists, and supporting members. She is also charged with accountability and accuracy for many items viewed by the membership: newsletters, bulletins, announcements, calendars, and various monthly and annual reports. She often serves as the liaison between staff, projects, and members. Her job is made easier through the graciousness of the staff, the wonderful volunteers, and the welcoming membership. ShelLu says she is blessed to work with a busy congregation with so many projects that help those in need. She relocated to Cheyenne from Torrington with her husband, and three furry family members, in late 2015.

Betty Jo is the keeper of the financial accounts for our church. All expenses are submitted to her so that we can be good stewards of the financial support our members and friends provide for our church and its ministries.

Becky Tish, Choir and Handbell Director
Music is deeply planted within Becky’s heart and soul. You can see it as she oversees our entire music program as she directs our Chancel and Handbell Choirs. Her gift of music is shared in making our services more meaningful by the excellent selections of music she provides each week for the choir.

Becky is also the inspiration behind our melodious ringers. With the ringtones of an adult handbell choir, our congregation is treated to a regular rendition of some of our favorite hymns played on the bells.

Eleanor Lane, Organist
Eleanor Lane, a life-long member of First Presbyterian Church, is the principal organist/pianist who provides service music for worship, as well as accompanying the chancel choir, soloists, and small groups. She is available to play for weddings, funerals, and other special events, and she is responsible for programming the carillon for changes in seasonal music.

First Church of Cheyenne was the first Presbyterian Church to be organized in the Territory of Wyoming on July 18, 1869 with nine charter members. The first building on the northeast corner of Eighteenth and Ferguson (Carey Ave.) was dedicated on July 17, 1870 at a cost of $6500.00. The church was named the Krebs Memorial Presbyterian Church, as a memorial to the lamented Dr. Krebs whose former congregation, the Rutgers Church of New York, contributed largely to the building of this church. Rev. Sheldon Jackson preached the dedicatory sermon and a collection of $150.00 was taken up , which put the church out of debt.

A new church building at the same location was dedicated in 1884, having been built for a cost of $14,000.00. The size of the church was 51’x85′, with a tower, 96 feet high, and main building 52 feet high. The bell from the old church hung in 1876 was placed in the tall steeple of the new church and continued to call worshipers until the building was torn down in 1925.

The current building at 22nd and Carey was dedicated on March 22, 1925. A beautiful memorial chapel in honor of the Presbyterian boys who gave their lives in World War II was dedicated on November 10, 1948. A new Christian Education wing was dedicated on September 17, 1961.
