The network includes trainers all over the country who have been screened, educated, certified, and approved by John to ensure clients are getting the very best aid in their quest to help their pet become a more ideal part of the family.
Cristin Ellis – Operations Manager
Cristin has been training dogs in agility for ten years but decided to focus on behavior after bringing home her Border Collie, Sike!. Sike! came with bad habits stemming from fear and anxiety.
Although Cristin had a good handle on behavior modification and canine psychology, it took working for Canine Trade Group and attending their in-depth training courses to help fix Sike!’s problems for good.
As Operations Manager, Cristin will not only answer a potential client’s call, she’ll be able to relate to and understand the client’s problem.
She lives with her husband and three Border Collies, Sike!, Elsa and Phineas.
Nicole Zulkowski – Veterinary Relationship Manager
Ever since she was a child, Nicole knew that she wanted dogs to be involved in her life and her career. She attended Ursinus College and graduated with a BS in Biology, aiming to work in the animal field. All throughout high school and college, Nicole worked various jobs involving animals. Later after graduating, she worked as a veterinary technician and as a handler at a dog daycare. It was here that her interest in dog behavior came to full fruition, and began seeking opportunities in the dog training industry.
Nicole found Canine Trade Group and joined their office staff, talking to owners about their dog problems and guiding them to the right training program that would address all their needs and training goals. She has studied the dog training course that Canine Trade Group’s trainers take, which has built her understanding and experience in complex canine behaviors.
She lives happily with her two dogs: her Pitbull mix named Willow and a Boston Terrier/Pug mix named Brooklyn.
