The cornerstone for the Mission Church was laid on the Feast of St. Ann and it took a crew of six men exactly one week, from the first discussion regarding the building of a church, to erect the new 28 foot by 68-foot mission church. The church, which could hold 300 parishioners, was named St. Ann in honor of the Mother of Mary and of Mr. Walsh’s wife, Anna. At one of the first organizational meetings, it was determined that the property, the church and all of its contents were worth $2,100. It also was resolved that due to the costs of heating the church and transporting a priest to Yorkville, the church would only be open in the summer months when there were more people at the lake. The first Mass at the mission church was an exciting event. For a round-trip fare of 50 cents, one could take the train (on which the Michigan United Railroad had added 2 more cars) and be dropped off directly in front of the church. Reverend Theodore Lochbihler presided over the Mass, the renowned speaker, the Very Reverend Dr. Morissey, C.S.C. of Notre Dame, gave a sermon and the St. Augustine Choir provided the music.

The St. Ann Mission church remained a busy place from 1911-1958, but in the 1950s there was a robust period of growth. In 1952, the church began holding masses all year round. The St. Ann’s Women’s Guild was founded in that year as well. Religious education became a standard in the ’50s as the Sisters of St. Joseph traveled from St. Augustine Church to teach Religion classes to the youth in the area.

In 1958, the St. Ann Catholic Parish was formed and Father Francis Murray became the Administrator of the Parish. By that time, the Old Mission Church structure was literally bursting at the seams, so Father Murray petitioned the Bishop to build a new church. In 1960 ground was broken on the current St. Ann campus, and a church and a social hall were built. The first mass was held in September of that same year and in 1961 the rectory was constructed. The Parish continued to grow and under the direction of a new Priest, Father Steffey, an educational and a social building were erected in 1967. Before he left for a post at St. Joseph’s Parish in Battle Creek in 1975, Father Steffey had the privilege of burning the building mortgage, and St. Ann Catholic Parish was debt-free.

St. Ann Parish has continued to expand and develop over the decades. In the late 1980s, the entrance to the church was remodeled and a stained-glass depiction of Gull Lake was erected in place of the old entrance. Due to the Parish’s growing population, it became apparent in the 1990s that there was a need for a Family Center where parishioners could gather and religious education classes could be conducted. As a response to this need, in 1998, with the financial support of the parishioners, the St. Ann Parish Family Center was constructed under the direction of Father Mark Vyverman. Between 2000 and 2001, during his tenure at St. Ann, Monsignor Mike Osborn had the church remodeled, focusing major changes on the chapel, the layout of the church, and the confessionals. The most profound change Msgr. Osborn made was to move the tabernacle from the chapel, back onto the altar, making the presence of Jesus the focal point of the church.

The future of St. Ann Catholic Parish is bright. More new families have joined the Parish, and many have taken advantage of the Catholic education of the St. Ann School, which was established in 2012, under the direction of Father Christopher Derda. With the guidance of Father Fleckenstein in 2017, St. Ann School was merged with Vineyard Academy to eventually become Light of Christ Academy under the direction of Father Marotti in 2018. In that same year, the parish was blessed with the addition of a pipe organ and a Marian Grotto. Additionally, Father Marotti began the process of acquiring the land next to and across the street from the church. Paid for by many generous donors, the land acquisition for The Sanctuary at St. Ann was completed under Father Tom McNally in 2020.

The Parish has many growing, vibrant ministries, and a large population of the parish engages in many activities including faith formation, Catholic studies, men's groups, various seasonal presentations, and several opportunities for fellowship and giving. Children abound and are a living presence of God’s work in the Parish.

The parishioners of St. Ann have surely been blessed. Over the years, through the guidance of the Holy Spirit and faith in God’s plan for the future of St. Ann Catholic Parish, parishioners have been shown that with the help of God, all things are possible.
