Therapy Dogs – New Jersey?

I recently adopted a cockapoo puppy, he’s 4 months old. He has a great temperament, intelligent and really affectionate, not overly aggressive. I think he would make a good candidate for a therapy dog. I am interested in learning more about the training of therapy dogs. I live in Morris County NJ and am interested in becoming involved in a Therapy Dog Group. Any helpful suggestions would be greatly appreciated! Thank You!
