Super Sonic Dog Training’s Office Team

John Van Olden – President/CEO

John started Canine Trade Group to help overwhelmed dog owners learn how to help their pet, young or old, fit in better with the family. Whether the problem is aggression, housebreaking, anxiety, or a more rare behavior issue, CTG’s certified in-home trainers can handle it and teach owners the tricks of the training trade.

CTG trainers are available across the country, and each one has been hand-picked by John to participate in this exclusive network of trainers. With over two decades of training experience himself, including presiding over two training companies and helping to found the International Association of Canine Professionals, John has a knack for recognizing the best of the best in dog trainers.

Cristin Ellis – Operations Manager

Cristin is Canine Trade Group’s Operations Manager, and she knows the ins and outs of the office better than anyone. She also knows the ins and outs of canine behavior. In addition to over ten years of experience in training dogs for agility competitions, she also took it upon herself to learn and practice CTG’s in-home training methods.

This helped the most with her dog, a Border Collie named Sike!, overcome the anxiety and fear aggression from which he initially suffered. Cristin knows the psychology, theory, and science behind CTG’s methods, and she’s seen firsthand just how effective they are.

She lives with her 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.
