S.,
I know this is further than you would want, but Celebration Covenant in Frisco is AWESOME!!!! Your kids will LOVE it.
They children's ministry is completely set up for them to want to come to church. They do skits and dress up in funny ways to get the message across. This is perfect for your pre-teen and especially suited for boys. There is a rock climbing wall and video games for them. Wendy Harmon who leads the ministry is AMAZING with children and they REALLY get it.
My daughter just moved up to the teen ministry and she LOVES it. They have contemporary worship and Christian based rap music. They are imparted with leadership values and really push kids to a higher standard. My daughter is upset to miss church (and she goes at least 3 times a week!).
My little one who is 3 goes to preschool there as well as the nursery and they do worship with the kids and teach them some Bible verses too.
But the BEST part of our church will be for YOU! Our Pastor, Keith Craft ROCKS!!!! He's a solid man of God who is down to earth, straighforward, and will challenge the way you think. We say around here that if you elevate your thinking, you elevate your life! The men in the church are STRONG Christian men who TRULY lead their families. I don't know about your kids' father, but I know when I was a single mom, this is where I wish I was so that my kids had strong male figures around them.
Check it out online at www.celebrationcovenant.com. You can watch some of the previous services to see if the message speaks to you.
Good luck to you!
