Meet the Canine Trade Group Office Staff

Cristin Nataro – Operations Manager

Dog training has always been a huge part of Cristin’s life. She has been training for over 13 years, she started with dog agility and earned two AKC Master Agility Championships (MACH) on her Golden Retrievers, Rocky and Hunter. She has also put several titles on breeds ranging from English Springer Spaniels to Border Collies.

Cristin’s third dog, a Border Collie named Sike! was the reason she became involved in dog behavior. When he was first brought home, Sike! slowly developed a variety of behavior issues, including fear aggression, anxiety, and resource guarding. Cristin pulled out all the stops while researching methods to help her dog, and in the end it was Canine Trade Group that used the most effective methods. She immersed herself in John Van Olden’s training and now Sike! is a happier, more relaxed member of the family. Her newest member of the family is a Border Collie named Elsa who is already showing great promise with her training.

Now, Cristin is starting her fourth year as Canine Trade Group’s Operations Manager, using her knowledge and experience to help other owners find a certified, professional CTG trainer in their area.

 Nicole Hanby – Veterinary Relationship Manager

Vet Relationship Manager, Nicole HanbyNicole knew ever since she was a young girl that she wanted dogs to be part of her life and career. Throughout high school and college, she worked different jobs that involved animals. Graduating with a BS in Biology from Ursinus College, Nicole began to look for work within the animal care field, and was employed as a veterinary technician and also a dog daycare technician/handler. After working with many dogs with a wide range of behaviors, Nicole was inspired to learn more about how these behaviors form, and also how to treat them.

Canine Trade Group is thrilled to have hired Nicole into the office staff. Along with her extensive knowledge on canine behavior and psychology, she also shows great care toward dog owners who are looking for ways to solve their dog’s behavioral issues. Nicole undertook the same trainer course that Canine Trade Group’s trainers did so that she could better address client questions, dog issues, and guide everyone to the right training protocol that would suit their needs and goals.

When she’s not busy helping other people and their dogs, she likes to hang out at home with her two dogs, Willow (a Pitbull mix) and Brooklyn (a Boston Terrier/Pug).
