Cristin Ellis – Operations Manager

Cristin works with John to connect dog owners with trainers in their area. Dog training has always been a passion for Cristin, who trained dogs in agility competitions for close to ten years with her Golden Retrievers, Rocky and Hunter before joining Canine Trade Group and learning more about the behavioral side of training.

Since the CTG techniques were able to help her train her own dog, Sike! a Border Collie who suffered from fear aggression and resource guarding. She is a true believer in the training, the process, and the company itself. Cristin works hard in the CTG office, and if you’re looking for a trainer, you may very well end up speaking with Cristin!

She currently owns three dogs, Sike! (12 yr old Border Collie), Elsa (5 yr old Border Collie), and Phineas (6 yr old Border Collie).
