About the Trainer

Mary Huntsberry, MA, is an Associate Certified Applied Animal Behaviorist who provides science-based behavior modification and training for dogs and cats. She specializes in addressing problem behaviors such as reactivity, fearfulness, resource guarding, separation anxiety, leash pulling, and stealing, using research-backed methods that lead to immediate results.

Mary offers both in-person and virtual consultations and training sessions, making her services accessible to clients locally in Montgomery County, MD, and beyond. Her approach emphasizes understanding the root cause of behavior issues, teaching owners how to communicate effectively with their pets, and providing detailed follow-up plans.

She does not offer boarding, grooming, walking, or daycare services, focusing exclusively on behavior and training.

Clients consistently report dramatic improvements in their dogs’ behavior after working with Mary, especially in areas like walking calmly on leash, reducing fear-based reactions, and resolving household conflicts between pets.
