Train the Bay trainer Dee Iaroli
Dee Iaroli, CPDT-KA, CGC Evaluator

Dee had a medical career as a Physician Assistant for many years and was slowing down her work schedule when in 2000 she rescued Farley, a Border Collie who “had issues”. With that, her journey into animal behavior took off.  She was motivated to learn quickly in order to manage Farley and keep him safe. 

At the time, she was a volunteer at Berkeley Humane, and she and Farley attended the classes and private consultations that were offered. Farley showed progress, which further motivated Dee to study for her professional dog training certification and to receive the CPDT-KA. Two years later, with dedication on both ends of the leash, she taught group dog training classes with Farley as the demonstration dog. Dee and Farley have come a long way, and Dee credits Farley for being a wonderful teacher.

Train the Bay trainer Karin Linden
Karin Linden, CTBC

A graduate of the prestigious Dog Training Internship Academy, Karin believes puppy and dog training should be designed to improve the quality of life of canines and humans both. She delights in teaching classes that are energetic and dynamic, taking the whole family’s needs into account. For the well-being of puppies and dogs, and clients’ peace of mind, Karin uses only positive reinforcement training methods. Real-life results are best achieved when everyone—trainer, dog, and client—are relaxed and thus able to learn freely. Karin is dedicated to ongoing professional education, including most recently enrolling in Florida Institute of Technology’s certificate of Applied Behavior Analysis.
