What we are

With so many families struggling with even the basics of dog obedience, this page is a breath of fresh air that shows the results and the training of real world dog training. I am a results oriented dog trainer and work any tools and techniques that get those results. So many families have gone to 6-12 even 18 weeks of dog training and still not even gotten the basics down. It is not supposed to be like that and I offer folks an alternative. For more of an insight of who are and to get a better feel for how we run things please visit our facebook page.

On the East Coast we have trained with Jeff Gellman, owner of ‘Solid K-9 Training’ who has many awards for the best board and train facility and is very well known for rehabilitating dogs that are marked ‘red zone’, overall a fantastic man and dog trainer/behavioralist. I made my way up to Nova Scotia, Canada for a shadow program with Ted Efthdyimiadis from Mango Dogs one of the best trainers in the industry dealing with rehabilitating dogs with real genetic aggression, dog aggression, human aggression, resource guarding, etc.

We have trained with the best which is why is we give people the best results.
