I am a positive reinforcement dog trainer helping families in Newton, Brookline, and Waltham, Massachusetts (MA). My work is based on the science of behavior and learning. Helping dogs and their human families live in harmony is my passion. Puppy training and socialization is a specialty of mine, and I have worked with hundreds of puppies over the years. I also do a lot of work around leash reactivity and can help with other problem behaviors such as jumping up, demand barking, potty training, crating, separation anxiety, resource guarding, simple leash pulling, and mouthing.
