DH is Lutheran (Missouri Synod). They're conservative, though not nearly so much as WELS. WELS is more fundamentalist and tends to separate from other Lutherans, according to what I've seen on the WELS website.
What you find in a service, varies. The Lutheran church has its own traditional service book, but lately contemporary services have been coming into the church. DH's church used to follow the service book every week, but nowadays they have PowerPoint and praise and worship choruses just like the other churches. If you want the traditional service, you have to get up for the 8am service.
