A.D.
I'm not Lutheran, (I'm Baptist), but I attended at Preschool Educators conference at Faith Lutheran Church in Flower Mound.
It's on the corner of Morriss Rd and Valley Ridge Blvd - just south of FM 407 on Morriss - and diagonally across from Marcus High School.
It was a beautiful church and the staff that assisted us were very nice. The sanctuary was gorgeus!!
I found the website: http://www.faithflowermound.org/
Good Luck finding a church home!
