Ryan - Trainer
Hello, my name is Ryan Zimmerer. I grew up on a farm around working cattle dogs, along as working around working Labradors that retrieved birds for us when we were hunting. After joining the Marine Corps I got out and went to college and got my degree in Farm and Ranch Management.
I have been around dogs my whole life training my own personal dogs to work cattle. For the last 4 years I’ve been a part of Adaptive Training Foundation as an athlete learning to workout around my amputation. It is a non profit gym in Carrollton that works with teaching veterans and civilians how to work out and exercise around their injuries and disabilities. I’m now a head trainer there working to help others learn to work out and take control of their lives again. Most recently I have trained my own service dog and found my true passion of working with dogs.
Training dogs to do obedience is the foundation for teaching service dogs, and something I take a lot of pride in. I look forward to working with and training your dog, helping him realize his potential of being the best dog around.
