Emily Goodman
Principal Trainer, Behavior Modification Specialist
Emily’s passion for dogs started at a very early age, and she spent her childhood hanging out with the neighborhood dogs. Once she had the chance to get a dog of her own, she brought Buster home. His complicated behavior issues introduced Emily to the world of dog training, and she was hooked ever since. Emily’s experience with dogs is diverse, and includes going to school for veterinary technology, competing in multiple dog sports with her Belgian Tervuren, Willow, and working in a shelter where she was the behavior and training manager. This background gives Emily a unique perspective on working through everything from basic obedience to behavior issues.

Ken Carpenter
Principal Trainer, Behavior Modification Specialist
Ken Carpenter's introduction to dog training occurred in 2000 when he adopted a 1-year old 80lb German Shepherd name Cruz. From the onset it was clear that Cruz needed not only basic obedience, structure and boundaries, but also behavior modification. Cruz was leash reactive toward some people and dogs, and an escape artist extraordinaire! Ken enlisted the help of trainer Bonnie Brown Cali, and together they helped Cruz become a fantastic companion. This was Ken’s first introduction to dog training, and he was hooked. The skills he learned with Cruz helped him train his next puppy named Roxi, a dynamite Belgian Malinois. Roxi's intuition and desire to learn lit the fire in Ken to become a professional dog trainer. Ken had a one-year intensive internship with a San Francisco dog training company. He also attended Michael Ellis School for Dog Trainers in Santa Rosa where he received a sound foundation in training theory and methods. He enjoys staying informed in the dog training world and attends yearly seminars and workshops, most notably with Julien Ryckenbusch an IGP trainer from France. Ken comes from a diverse work background. Originally a professional cyclist representing the US in two Olympics, and later an Institutional Banker at a boutique firm in San Francisco. This diversity and dedication helped him gain unique instinctual, observational and analytical skills which he puts to good use training dogs and their owners. In his free time Ken practices his other passion, Jiu Jitsu, and finds that it compliments dog training immensely. Keeping calm, thinking through problems and puzzles are necessary in both martial arts and dog training. In addition, he trains French Ring sport, currently with his rescue German Shepherd Malinois cross, Ryker

Diana Santoyo
Associate Trainer
Diana’s love for dogs started when she was very young. If there was a dog around, people knew where to find her. She says dogs have always given her a sense of companionship, the feeling of a long-time best friend. In 2020 she brought home her first dog Sky, a spunky rescue Dachshund mix. It was not long before Diana knew she needed a professional trainer to help Sky overcome her reactivity toward people and other dogs. Diana immersed herself in learning about dog obedience, behavior modification, and the importance of quality canine nutrition. She realized her desire to advocate for dogs, and to be a part of the solution for those left behind. In 2022 she made the decision to follow her passion and is now an Associate Trainer with Dog Dynamics. Diana’s innate sense of how to communicate with dogs and people make her a good fit for the Dog Dynamics team. She is the point of contact for phone communication and social media, and assists in group and private training sessions. Diana loves working with dogs of all breeds and temperaments. She says this is necessary in order to understand dogs as a species. Diana has her B.S. in Food and Nutrition from Sacramento State University. She is also an avid learner and strives to further her education and certifications in dog training and canine nutrition. In her spare time, Diana coaches Olympic lifting at a local gym in the Concord area and is an avid photographer. You may also spot her with Sky hiking the hills around the Bay Area.

Isabel Zabronsky
Apprentice Trainer
Isabel’s interest in animals began at a young age. In 2016, she convinced her parents to add a dog to the family. This dog was a two-year old rescue beagle named Snoopy. While Snoopy was advertised as a friendly, well behaved pet, it soon became clear that in reality he struggled with many behavior issues including dog reactivity. Seeking professional help, the Zabronskys turned to Dog Dynamics. This is when Isabel’s passion for dog training truly began. Isabel was blown away by the positive changes she saw in Snoopy’s behavior after only a few short months of training. As Snoopy became a more trustworthy and stable dog, Isabel came to a realization: training allowed Snoopy to safely enjoy more freedoms and therefore improved his quality of life. This inspired her to learn as much about dog training and behavior as she could. In 2018, she began working as a kennel assistant for Dog Dynamics. Being able to help other dog owners improve their dog’s quality of life through training was even more rewarding than Isabel could have imagined. Even six years later, Isabel and Snoopy enjoy training together and work on scent detection, advanced obedience and AKC trick dog titles.
