John is very knowledgeable in his field. Lola actually began to listen as if the words were magic. Amazing!!! John is patient and I enjoyed the presentation. As I said, he is amazing. I felt as if a huge weight had been lifted off me. John taught me so much about dogs, I think I know Lola much better now. I feel this company is good for everyone, and for those that are handicapped, it is especially good because they come to your home. You get a personal trainer that fits the program to your needs. The structure of the program is amazing.
