The Trainers

Joel Beckman is the leader in the dog training industry partly due to what he learned training marine mammals and other exotics. So he has hired and personally trained a staff that also has this unique experience and perspective. No other dog training team in the county has the experience of the Beckman’s Dog Training team. Guaranteed!

Joel Beckman

While receiving an exotic animal education and training degree from Moorpark College, Joel Beckman devoted several years to training, caring for and performing with big cats, monkeys, camels, birds and many other exotics. At this one of a kind animal program Joel learned about conservation, educating the public, veterinary practices, proper cleaning procedures, animal ethics, entertainment and of course animal training. This experience led to Joel’s next position as a Killer Whale trainer at a world famous theme park in San Diego, California. This job not only allowed Joel to train and perform with Killer Whales, but it’s also where Joel met the love of his life. Joel uses positive reinforcement training. This is the preferred method for most marine mammal trainers, big cat trainers, therapy dog trainers, agility trainers, search and rescue trainers and many other animal training professionals.

Joel Beckman has developed a one of a kind unique dog training program that’s derived from his diverse education, training and employment. With a deep profound love for dogs, and more than five years of Killer Whale training experience, Joel decided to bring his knowledge and expertise to training dogs. Joel is the most knowledgeable and skilled animal training professional in the San Diego area. He is an expert on animal aggression and has a deep passion for animal training.
