In the 1950s on land in Sun Valley donated by Mr. Gepford, construction of a church was begun. It was named to honor Peter Coressal whose family and relatives from Ohio assisted greatly in building St. Peter. By 1972 a priest, Fr. Vincent Squatrito, was assigned to the parish on a regular basis. A small mobile home was purchased to serve as his living quarters and the parish office.

The parish continued to grow with both English and Hispanic parishioners. Fr. Squatrito brought the Madrecitas (Spanish-speaking Sisters) and the Sacred Heart Sisters to help with the religious education of children. In the 1980s more space was needed for the growing community and Father helped the parishioners build and dedicate the parish hall, currently used as the “big Church” With the departure of this devoted pastor in the late 1980s, the Madrecitas also left in 1996.

Father Larry Morrison was the Administrator/Pastor from 1996 to 2004. Under his direction, the parish offered three Masses on Sundays, two of them in Spanish. The “big Church” was re-carpeted in 1996 and new chairs were purchased in 1998.

In 2004, Father Guillermo Arias was appointed Parish Administrator. Father Guillermo retired in 2016. Immediately after, Father Edgar Villanueva was appointed Pastor of St. Peter’s. Since then, he has worked very hard hand-in-hand with the parishioners to raise the funds to increase the much-needed church space, so parishioners don’t have to worship in the dirt parking lot outside the church. At the present time, St. Peter’s serves more than 2,500 parishioners each Sunday, of which 98% are Hispanic. Their current worship space occupancy is less than 300 people. In addition to their need for increased worship space, the church expansion project will not only provide a safe and modern structure but most importantly, it will provide more areas for children’s religious instruction and sacramental preparation.

St. Peter’s currently has 875 students between the ages of 7 and 17 enrolled in faith formation classes… and at the present time, they only have 2 classrooms for instruction. With this addition, the worship space will increase to a capacity of 800 people.
