Our Mission

At Rocky Mountain Dog Training, our mission is to teach leadership and team driven skills and handling techniques that are sensitive to both the human and canine needs. We offer pet dog training, therapy dog prep, behavior modification and tricks training. We are solutions driven, positive reinforcement style trainers who focus heavily on motivation and having fun. No matter how serious the behavior, our goal is to make this experience rewarding for both you and your dog. We strive to build communication skills for mutual understanding between you and your dog, provide quick installation methods of basic skills, and focus on prevention and/or modification of undesirable behaviors.

Julie Parker (CTC)

Owner, Trainer

Following 17 years of volunteer work in shelters and rescues, Julie wanted to get on the preventative end of the spectrum and so shifted careers where dog training has been her focus to that end since 2008. She specializes in pet dog training, puppy socialization, and leash reactivity. Julie initially completed schooling through Canine Correspondence Studies, and recently and additionally graduated from The Academy for Dog Trainers, an advanced, highly prestigious program for dog training professionals, earning her CTC. 

Julie founded Rocky Mountain Dog Training in 2009 with the goal of providing her community with science-based, humane training solutions focused on prevention and behavior change while protecting the dog's temperament. She currently teaches our level 1 and 2 group classes, puppy socialization and works on business development projects. She is not currently taking private training clients.  Julie enjoys hiking, ping pong, and spending time with her spouse Ray and their dogs Marshall, Dexter, Midge and Aiden.



Mary is committed to force-free, evidence-based training. She most enjoys helping fearful and reactive dogs learn to be more comfortable in the world and here at RMDT assists on the bulk of our behavioral cases and leash reactivity classes.

Mary spent several years working as an Animal Care and Adoption Counselor, then Supervisor at the Massachusetts SPCA before relocating to Boulder in 2015 to pursue her passion for dog training and behavior at the Humane Society of Boulder Valley’s Training and Behavior Center. She has also worked as a veterinary technician and in animal welfare legislation for the HSUS.

Mary holds a BS in Psychology and Biology from Northeastern University, with a concentration in behavioral course offerings. She is a Certified Professional Dog Trainer and has her Certificate in Training and Counseling from Jean Donaldson’s Academy for Dog Trainers. When she is not working privately with clients, Mary also works as a Professional Behavior Responder for the ASPCA's Anti-Cruelty Behavior Team. In her free time, she enjoys skiing, climbing, running, and playing soccer. You might see her out on the trails with Buster, her adopted Chow/Akita mix!



Val caught the training bug when she came through classes as a student in 2013 and became fully obsessed with the study of animal behavior. Valarae's primary focuses are group classes and puppy socialization both as lead and assistant. She assists with our Reactive Rover classes, works privately with our puppy clients, and just generally helps RMDT to run like a well oiled machine!



Laura DeMaio Roy has been working in the service dog and pet dog industry since 2010.

After a three-year apprenticeship, she became a certified guide dog trainer/instructor and has trained dogs across the US and Canada. She takes the principles of having a well-trained service dog and applies them to everyday pet training, so you can have a well-behaved companion that enjoys family life. Her focus is looking at each dog as an individual and bringing out the best in that dog.

Laura also loves trick training, disc, bikejoring and camping and hiking with her dogs. She’s a certified trick dog instructor and stunt dog judge, holding titles in disc, tricks, herding and barn hunt. She incorporates a variety of sport-dog concepts into her training to promote a fun learning environment for both humans and dogs.

Laura works in the RMDT puppy day training program to give each puppy the best start in life through socialization and training.


Julie and the gang have saved us! Just when you think you can't do it anymore Julie gives you the tips, courage and support to keep with puppy training. She has helped us turn our Hattie into a great dog. I would recommend her to anyone and will continue to sign up for on-going classes! Thanks Julie you rock!
