How will I find addiction treatment centers in Winterport, Maine?

My dad lost his job because he was caught in the office drinking alcoholic beverages. This circumstance, instead of pushing him to change, only got him to drink more. He’s been taking swigs from the bottle every now and then. Just last week, my mom has had enough and just decided to leave us. I guess this is what got my dad’s attention. I have seen him resisting alcohol, but I guess the withdrawal symptoms are just too much for him to bear. Now he wants to change already and get himself treated. I want to find addiction treatment centers for him. How?
