About Us

Our origins

Founder and Dog Trainer, Leighton Oosthuisenemigrated from South Africa to the USA in 1992. Prior to emigrating, Leighton had been the dog trainer for a Hollywood movie production filming in South African.
Leighton also served in the South African Police, Search & Rescue, and in the Military working dog unit, specializing in Explosive and Narcotic detection K9’s.

He started dog training in 1973 at a mere 10 years old and in 1985 joined a dog training school as an apprentice, going on to become an Instructor and later, Head Dog Trainer.

In December 1997, Leighton purchased an old race horse training facility in Cave Creek, named Lone Tree Ranch, and founded Partners Dog Training School. (The “Lone Tree” still exists on the main training field). This laid the foundation for what was to become one of the biggest dog training schools in the USA.

While training detection canines, he met his first civilian client, a Great Dane puppy, in a park near Paradise Valley Mall, and by word-of-mouth, Leighton built a following of dedicated loyal customers, most of which are still with him to this day. 

His goal was the same then as it is now, “Training Good Dogs to be Great”, and as they say…the rest is history.
