St. John Vianney is located on the east side of Janesville, Wisconsin. Our church was established in 1955 with approximately 350 families. Today our church is thriving and has almost 1400 families. We have many dynamic volunteers who contribute to our reputation as being a leader in the community. We invite you to attend Mass this weekend -- Saturday at 5:00 p.m. and Sunday at 8:15 and 9:45 a.m.
