How Can I Find an Addiction Treatment Center for Gambling Addiction in Kemah, Texas?

My brother’s always gambling his money away. He incessantly asks our parents for money and then he just uses it so he could gamble. He would make up a variety of excuses to explain where the money went and my parents actually believe him. I think I’m now ready to tell my parents about what he really does. I also want to find treatment centers that can deal with his case. How?
