Meet Sean Miller

President and Training Director

Sean has been a lifelong animal lover, with a deep fascination for animal behavior. It is this passion that has led him to dedicate his life to the training of dogs.

The only thing that rivals Sean’s love of animals is his passion for exceeding the expectations of his clients. Sean cares deeply about helping other owners achieve their goals, and he wants to make sure all the clients who trust his company with their dogs see the results they desire.

Sean originally went to school for firefighting, pursued his education in business and worked in the corporate world. He was also a dog training hobbyist for approximately 10 years including a three-year internship with police and military trainers in the midwest. Upon realizing that his passion was working with animals, he pursued dog training full time. He has since spent more than 19 years as a professional trainer, specializing in behavior modification, animal behavior, pet dog training, dog sports, service dog consulting, and teaching young trainers how to develop their skills with dogs.

In his career with dogs, Sean has provided trained dogs for TV and advertisements. He’s also created and implemented community safety programs for dogs with multiple local police departments.

When he’s not teaching clients or training dogs, Sean spends time with his family. He enjoys Brazilian Jiu-Jitsu, mountain biking, traveling, and other outdoor activities.

You can also count on us to offer perks you won’t find at other companies. We have affordable boarding packages to help you save while you travel. We also offer a lifetime canine guarantee.

Four Quadrants Of Operant Conditioning

Training That Is Positive, Patient, and Practical

To understand what we do, start by understanding the four quadrants of operant conditioning. To be clear, in this application, positive and negative do not mean good or bad. More specifically positive means to apply and negative means to remove.

An example of positive punishment would be someone raising their voice at the dog. They are attempting to reduce the frequency of a behavior through aversive means. Meanwhile, some examples of positive reinforcement would be praising your dog, petting, food, or toy rewards to increase the frequency of a behavior.

We’ll help you determine which type of currency best motivates your dog. Then, we’ll spend time teaching a new behavior with praise, encouragement, and rewards. Once your dog has a very clear understanding of what our expectations are, we can move on to numerous repetitions with few distractions.

As your dog’s understanding of the exercise increase, we can expose them to more distractions with guidance from our voice and a leash. We’ll take them into the final stages of training by proofing them to increase their ability to generalize and become obedient in all or most environments. This balanced approach achieves better, more sustainable results.

I’ve taken my dog here for boarding multiple times. The attention to detail and friendliness of the staff is excellent. My dog has allergies and is only able to eat raw food. She is also very picky about socializing with certain dogs. The staff has no problem accommodating her needs and ensuring she has a comfortable stay.
