ABOUT OUR TRAINERS

Meet The Off Leash K9 Team

Tiffany - Owner

Tiffany is the owner of Off Leash K9 Training of Amarillo and Lubbock, TX. She has been with Off Leash K9 Training for 5 years and she’s still loving every minute of it!

Tiffany’s greatest enjoyment comes from keeping dogs out of rescues/shelters, and making it to where people actually enjoy their dogs! Dogs are man’s best friend!

Working with dog’s on Behavior Modification is Tiffany’s specialty. She’s had amazing success with dog’s with a multitude of issues from aggression and reactivity to dogs with separation anxiety.

She currently has 3 dogs: Thor (German Shepherd), Crush (Malinois) & Leo (Ridgeback).

In her free time, Tiffany can be found riding horses or enjoying the lake with her dogs and family.

Tiffany was once asked what piece of advice she would give other dog trainers: “Not all dogs can be treated like humans. They are domesticated, but they are still canines. They need pack structure and leadership. Always keep that in mind when something isn’t going right. Think like a dog, not a human when you are struggling with them.

Denise - Sales Manager

Denise was born and raised in Westampton, New Jersey, which is a suburb of Philadelphia, and has spent her entire life around dogs. She and her family rescued basset hounds and volunteered with the local basset rescue there. After graduating with a Bachelor of Arts in Communications from Ursinus College, Denise pursued a federal law enforcement career with the United States Secret Service. This is where she met and worked with OLK9 founder and owner, Nick White.

When she wasn’t spending countless hours on the Surveillance Team at the White House, Denise could often be found dog-sitting for one or more of her co-workers. Because of the long hours she worked and her living arrangements, Denise was unable to have a dog of her own, so she would take on the temporary role of dog-sitting for her co-workers when they would be called on work trips or vacations. From chihuahuas to English mastiffs, Denise was the go-to Mary Poppins amongst her peers.

After Denise left the Secret Service, she moved to Phoenix, where she continued her career in the security field for another 6 years, both in the private sector and for the state. Knowing it was something she was good at but tired of the same old routine, Denise realized she wanted to finally pursue her dream and work with dogs. Denise is excited to bring the same training techniques used by military and law enforcement to the Valley of the Sun, in order to achieve precise and flawless obedience to household dogs, 100% off-leash.

When Denise is not training dogs, she enjoys spending time with her rescues; Penny, Siggy, Ari, and Pearl! She also enjoys photography, baseball, storm chasing, and is a certified canine nutritionist!
