About Me

Hi! I’m Diane

Professional Dog Trainer

I believe in positive reinforcement training.

Diane grew up in Northwest Washington where her love for animals started. Her love for training flourished at a young age when she took dog training classes with her own dogs. She also was responsible for the care and training of her horse.

In 2005, she began her career as a certified trainer at PetSmart. Two years later she started her own business “Aspen Family Dog Training” in Highlands Ranch area. She has owned and trained her dogs as Therapy dogs in the Seattle area with the Delta Society.

Diane teaches group training classes and private in home dog training in Highlands Ranch, Parker, Centennial, Denver, Littleton, and Castle Rock. She also teaches Obedience 1 classes in Golden with Pupessori.

In her spare time, Diane has a passion for canine photography. She also enjoys spending time with her Golden Retriever “Porter”. Diane is a knowledgeable, fun and positive trainer.

Diane is a member of APDT, The Pet Professional Guild and continues to learn from some of the top dog trainers in the country.


I built Aspen Family Dog Training to offer positive reward-based dog training classes in the South Denver area, including Highlands Ranch, Littleton, Centennial, Denver, Castle Rock, Castle Pines, Lakewood, Golden, and Parker.

We offer group classes every week, as well as in-home private dog lessons and behavioral consultation. We teach puppy training, basic, intermediate, and advanced dog training classes. Private classes will be customized to fit your dog’s individual needs.

We teach both owner and dog to become a successful team. Dog training for the whole family ensures a happy, rewarding life together!

I Work With You and Your Dog to Make Training Fun.

You’ll learn the necessary tools to communicate with your dog through mutual respect and trust. Quickly you’ll find that your dog wants to please you and be a great member of the family.

Here’s a few ways I can help you enjoy life together:

Puppy Training

Everyone loves a puppy. It’s critical to make sure you begin their dog training early to ensure that they understand how to be a happy member of your family for years to come. Basic skills, house training, and crate training can begin as early as 9 weeks!

Basic and Advanced Obedience Dog Training

Whether you’re wanting the basic skills mastered or more advanced training, like a therapy dog, we’ve got you covered. Your dog will learn the basic commands like sit, come, leave it, and leash training to become a great companion and family member. Or take it to the next level with your dog being able to hold the commands longer and learning tricks. 


Behavior problems can be stressful and frustrating for both you and your dog. I can help you modify such behaviors as fear, aggression, excess barking, house training, and many more. 

Happy Clients

Golden Retriever Face | Aspen Family Dog Training | Highlands Ranch, CO

Over the past decade, I’ve taken 3 rescue dogs to Diane’s training classes at Wag ‘n’ Wash. Diane has small class sizes, so there is a lot of focused interaction between each dog owner, their dog and Diane. Smaller classes are also safer for you and your dog. Diane has excellent command of everything happening in her class. If you follow Diane’s precise, focused instructions, and practice that training daily in your home, you will see much positive progress in the confidence and behavior of your dog. It’s a treat for me to highly recommend Diane’s dog training!

Diane is a great instructor that focuses on positive reinforcement. I took two sets of classes with my Bernese puppy and he did great. Highly recommend!

Happy Dog | Aspen Family Dog Training | Highlands Ranch, CO

Diane is the best trainer out there! She helped me train my crazy husky puppy to be well behaved in just a 6 week class. She knows so much and is very patient with the dogs. She treats everyone with so much kindness and only has love in her heart!!! She even opened a new class to accommodate my schedule which was the most helpful thing ever. AMAZING!
