I have taken three of Grisha's classes now and I cannot say too many good things about Grisha, her gentle and thoughtful approach, and her knowledge of canine behavior. Grisha is always creative and humorous--and she really gets results.
I work in rescue, and many dogs we get are frightened or aggressive. My own dogs are too. I have taken other classes and read extensively--but Grisha's well run and well organized classes synthesized it all and gave me a flexible structure to work with.
I could go on raving and raving. Suffice it so say, if I could give her 10 stars I would!
