In The Beginning

Partners Founder, Leighton Qosthuisen, emigrated from South Africa to the USA in 1992.

In 1973, Leighton started training dogs 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.



Leighton purchased an old racehorse 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).
Partners opens its brand new training facility at its Cave Creek location, complete with large indoor training areas, zoned AC, and 15,000 SF. training field.



Partners launches its full-scale Daycare program with 12,000sf of indoor/outdoor play areas, 10 to 1 ratios, and a focus on well-mannered, positive play.
Partners upgrades its Boarding facilities with luxury suites, tiled floors, industry-leading cleaning systems, and unique services optimized for pet experience.



Partners opens its second location in Scottsdale, Arizona. Doubling our team to 50+ trainers to help operate our new 23,000sf. luxury resort and school.

On its 25th year anniversary of the school, Partners University is launched with its first course, the Pet Parents Guide to Success to assist all of our current and future clients in their journey to a delightful relationship with their dog.

Meet Our Founders: Pioneers of Arizona Dog Obedience Training

Leighton Oosthuisen


Hello! My name is Leighton and I started Partners Dog School in 1997 after immigrating from South Africa with my family. I am a former K9 handler and have worked with bomb dogs, drug dogs, and Search & Rescue dogs. I have also competed and titled dogs in French Ring, Agility, Dock Diving, and Schutzhund. For the past thirty years, I have specialized in behavior modification. I currently live at our Cave Creek location with my family and an assortment of animals. I am also a World Champion target pistol shooter and represented the USA in 2014, 2017, and 2021 World Pistol Championships.

Christopher Oosthuisen


Hi there! My name is Christopher and I oversee the operations of each PDS location, Partners Dogs University, and Partners Dogs Foundation. I’ve been with Partners for over a decade, and in that time I’ve seen 10s of thousands of dogs achieve a delightful relationship with their Parents. My goal is to empower our team to inspire our guests into making training a daily part of their lives. I also participate in French Ring and rank Top 50 in the world in target pistol shooting. I have represented the USA alongside Leighton in 2014, 2017, and 2021 World Championships.

Hello! My name is Megan and I have worked at Partners since 2016. I not only manage the day-to-day operations at the Cave Creek location, I also work with most of our behavior modification cases. Even after all of these years, my favorite moment is still the “Ah-Ha” moment between handler and dog, the moment where communication is clear and we truly understand one another.
