I signed up with Mariano for personal lessons about a month ago. I have a European working Dobermann currently 3.5 months old. Mariano has came to Our home for the 3 lessons we have done so far and we are so happy with what he has taught us and Copper our Dobermann. I contacted other trainers and did not feel very comfortable with them. Copper loves it when Mariano comes over for our lessons, he gets extremely excited and is eager to learn. Once Mariano leaves, I continue to apply what he has taught me and Copper picks up on it quickly. I highly recommend Mariano and am excited to continue our lessons with him as he is very personable with us and our dog. He is a great dog trainer.
