Houston Area D&D for Teens/Pre-Teens

Does anyone know a gaming store or group that offers D&D sessions for pre-teens and teens? One of my kids wants to get more into it but doesn't have a group. I also want him to get out and socialize more.

Preference is something on the west side of town, particularly anything near Sugar Land/Richmond/Rosenberg/Katy area, but we'd be happy to try something up near the Woodlands too.
