John and I (Kathy) have just finished a six week training class with Lisa and Dave with our one and a half year Lab, Beckett. She was out of control when we took her to them.. Pulling so hard we could not walk her and not basic obedience trained. We could not be happier with our experience. She is a different dog and now one we can really enjoy! I cannot recommend them more.. they are professionals and good friends after this experience.
