How Am I Going to Find Addiction Treatment Centers in Voorhees, New Jersey?

My cousin lives there. The last time I went to visit, she was still the lively person I had always known. Today, though, her brother called me and told me that she has been turning to alcohol more and more. This really saddened me, since I had always looked up to her as a well-grounded, rational person. Her brother told me that she started drinking alcohol when she and her boyfriend broke up. I just really want to help by trying to find an addiction treatment center for her. Any ideas on how?
