"Over a lifetime of having dogs, Dina is the best instructor we've ever had. She's smart, clear, kind, fun, and patient. There's no behavior she doesn't know how to help with. She so clearly loves what she does and was amazing in including our 8 year-old daughter in the sessions. And she was able to effectively do it all over Zoom!"

"Seeing eye dogs, bomb-detection dogs, search and rescue dogs, and cancer detection dogs are my inspiration.

Very few creatures have coevolved the way man and dog have. We have actually effected each other’s evolution. Dogs guarded our agriculture, livestock, and our communities, helping man to make it past the agricultural stage, and bringing us to where we are now. We, in turn, have allowed these wonderful dogs into our homes, forever changing their evolution, as well."

"The connection between man and dog is magnificent. We were meant to help each other. There’s nothing else quite like it.”
