He should definately check out Buckhead Church! We go there with our kids (kindergarten) and they love it, but we hear AWESOME things from the teenage and the college age groups. Every meeting is like a rock concert, and they can join a 'small group' which is more like an accountability group or a place to bounce ideas off of kids their own age, struggling with the same issues everyday.
Check out their website - www.buckheadchurch.org and click on Before You Attend.
Good Luck!
