Bill Oliver was recommended to us by 3 neighbors and he was everything they told us about him. Coco is a rescued Shar Pei and we decided she needed private training. Bill worked magic that's all I can say. Coco came home and is still following commands. She is a much calmer dog. We plan to continue with his obedience classes in the hopes that she will continue to learn a few new things. I would highly recommend him to anyone who needs training for their dog!!
