Meet the DFW's Off Leash K9 Team

About Justin 

Justin is the Regional Director for the DFW area. He has had a relationship with dogs since he was a young boy. Growing up he and his father spent most of their time training and working with hunting dogs.

At the age of 18 Justin enlisted into the United States Marine Corps and was stationed in Okinawa, Japan, served in Operation Enduring Freedom and was deployed to Afghanistan.

Justin found his passion for dog training after he separated from the military and became best friends with a German Shepherd named Kara. Justin and Kara came to Off Leash K9 Training so that Kara could be trained as a service dog for personal needs. He was so inspired by this training that he knew he had found his calling and decided to become a trainer himself.

Since starting as a trainer with Off Leash K9 Training in the beginning of 2017, he has helped hundreds of dogs and their families. He and his wife Mallory reside in the DFW area with their 2 dogs, Kara and Ford.

Mallory aided her husband Justin with his many training dogs, utilizing and incorporating her extensive equestrian knowledge.
Mallory and Justin reside in North Texas and have two dogs, Kara and Ford. Ford came from an abusive home and Mallory dedicated many hours to build his confidence and trust through obedience training and then advanced on to retrieval work.


Our amazing Trainers

Brandon - Trainer

Brandon served 7 years in the Air Force Security Forces, the last part of it as a Military Working Dog Handler. After his honorable discharge, he completed a 3-month trainer course at AK9I in Virginia where he learned more complex ways of teaching and training dogs. He graduated with his working dog “Monkey”, an 18 months old Malinois certified for patrol and explosives. Brandon’s passion has always been dogs and figuring out what makes them “tick”, which is why we’re happy to have him on board. His easy-going personality and calm demeanor prove him to be an excellent addition to our team.


Brian - Trainer 

Brian started off as our client 2 years ago but has been dappling in training ever since.

He lives on a ranch with his spouse of 15 years, horses, chickens as well as his 2 German Shepherds, Winston and Sadie, and 2 cats. In his free time he enjoys the outdoors while fishing and horseback riding.

Since Brian joined our team he’s changed many clients’ lives by training their dogs successfully in the Board & Train as well as private lesson settings.


Ryan - Trainer

Hello, my name is Ryan Zimmerer. I grew up on a farm around working cattle dogs, along as working around working Labradors that retrieved birds for us when we were hunting. After joining the Marine Corps I got out and went to college and got my degree in Farm and Ranch Management. I have been around dogs my whole life training my own personal dogs to work cattle. For the last 4 years I’ve been a part of Adaptive Training Foundation as an athlete learning to workout around my amputation. It is a non profit gym in Carrollton that works with teaching veterans and civilians how to work out and exercise around their injuries and disabilities. I’m now a head trainer there working to help others learn to work out and take control of their lives again. Most recently I have trained my own service dog and found my true passion of working with dogs. Training dogs to do obedience is the foundation for teaching service dogs, and something I take a lot of pride in. I look forward to working with and training your dog, helping him realize his potential of being the best dog around.


Lisa - Trainer

Lisa was born in Dallas and has had a passion for animal behavior since she was a kid. With over 5 years of experience training dogs in obedience, conducting group classes, and private lessons, she absolutely loves to assist owners with their dogs. Lisa has spent 6 years working alongside law enforcement with K9 handler courses, certifying K9 teams, and training detection dogs in a variety of fields (narcotics, explosives, cellphones, bedbugs, patrol and tracking). She currently has a retired 9-year-old Belgian Malinois trained in explosives detection that she raised as a puppy and worked together with on contract searches for college stadiums, cruise ships, and local middle and high schools. Lisa is able to adapt to each dog in what motivates them, how to discourage certain behaviors, and reach the goals the owner wants. Even with working a variety of police K9s and pets, she will tell you the best dog she has ever trained off leash was a little Pug named Roxy whose owners to this day still take her off-leash to Galveston beach.


Brittany - Trainer

Brittany has been in love with animals since she was a young girl. Her passion and dream was to grow up rescuing and training animals of all breeds. As a young adult, Brittany rescued a cat named ‘Panther’ off the streets and leash trained him in obedience. A few years ago Brittany adopted her first Pitbull named Lana, it was at that moment she discovered her true passion for training animals. She began donating her time to non profits, assisting in the care and training of rescue dogs. She began professionally training with Off Leash K9 Training DFW in October of 2019 and has helped several families and dogs since then.
Brittanys favorite aspect about training, is learning and assisting with different personalities and behaviors. Each dog has its own personality, and she loves bringing out the best with each client she works with.


Laci - Trainer

Laci has had a relationship with animals since she was a young girl. Growing up raising horses, cattle, and dogs has given her quite a bit of experience. Her father, was a very experienced hunting guide, and most of her childhood was spent assisting him in the training and guidance of bird dogs.

As a young woman, she entered the world of Schutzhund where she gained hundreds of hours of experience in the sport of working style dogs. She has two German Shepherds, Kenai and Nova, that are highly trained and experienced in this style of work. 

Laci comes with an extensive background in working with clients and animals. Her favorite aspect of training, is problem solving the scenario, and helping the family become better bonded with the animal.
