On Sunday, October 25, 1987, the first official service of the River Valley Baptist church was held in the gymnasium of the Lincoln-Hayes School on Cottage Avenue in Ansonia, with an attendance of 28 people. Sunday School and morning and evening services were held at the school, while mid-week Bible studies were held in various individuals' homes on Wednesday evenings. The small church began to grow through careful and thorough Bible teaching and preaching and the personal evangelistic efforts of the members.
By 1992, it was apparent that the church needed facilities that could be used seven days a week, if necessary. A store front building was rented on Clifton Avenue with two floors providing adequate room for a sanctuary, as well as youth room, childrens' Sunday school, and a nursery. Over the next seven years River Valley Baptist Church experienced substantial growth and received front page publicity from the Connecticut Post newspaper, detailing the history and ministry of the congregation.
In 1999, while taking care of some business in the downtown area of Ansonia, Pastor Aabye noticed a large bank building on Main Street was for sale. The size, location, and enclosed parking lot seemed just right for a permanent home for the growing ministry. The congregation met in the available building for prayer and God's guidance concerning the transaction. The process moved along well, the purchase was made, and the congregation set out to renovate the building into a church. In February of 2000, a special dedication service was held at the new building at 355 Main Street, Ansonia, CT, with over 150 in attendance!
