Meet the Office Team at Show Me Dog Training 

John Van Olden – President/CEO

John Van Olden has dedicated his life to helping dogs and their owners form and maintain strong, lifelong relationships. He discovered his passion while training K-9s (police dogs) as a military policeman, and the urge to continue working in the field of canine professionalism stuck with him. After completing his service, John began his own training franchise and sat on the Board of Directors for the International Association of Canine Professionals. He also presided over another training company called PAWSitive Solutions and began a school for dog trainers.

But John’s pride and joy is Canine Trade Group, a network of dog trainers (including Show Me Dog Training) that serves owners in need across the nation. The CTG network allows owners to contact a certified, professional in-home trainer by calling a single toll-free number or by sending an e-mail. Instead of sifting through trainers and training styles, let John and his twenty-plus years of experience do the work for you.

Cristin Ellis – Operations Manager

Cristin is Canine Trade Group’s Operations Manager and an experienced trainer in her own right. Her knowledge and perception has earned her trainees several competition titles over the last ten years, including two Master Agility Championship Titles, attending two AKC National Agility Championships with her Golden Retrievers, Rocky and Hunter.

But Cristin’s true passion is in canine behavior training. After attending the CTG certification courses and seeing how well the training worked on her own dog, Sike! who suffered from fear aggression and resource guarding, she decided to focus on behavioral training and help other struggling owners learn how their problems can be solved with the help of CTG trainers.

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

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.
