Denise is amazing. She achieved quick results with my rescue dog Corky (and me). She trains both you and the pet... you to be the "pack leader" and your pet to follow basic instructions.
Too many people treat their dogs like people instead of like the pack animals that they truly are. Unless you become the pack leader, your dog will attempt to assume that role which can actually be stressful for the pet. Let Denise guide you and your dog through her process for a rewarding experience for both yourself and the pet.
