Most ELCA congregations within the Rocky Mountain Synod have an active women's group. The easiest way to find yours is to call your local church office and ask whether there is an active WELCA chapter at your church. Your pastor or anyone on the church counsel should be able to put you in touch.
If you are looking for a church, there are many things to consider besides proximity such as congregational size, staffing, and programs. You may need to try a few congregations on for size.
