Kirsten Hansen, Dog Trainer 

Kirsten Hansen oversees Canine Behavior Science’s day training, dog manners and puppy programs.

Kirsten has always enjoyed dogs, but she became interested in dog training and behavior with her beagle, Baxter.  Kirsten worked with trainers to try to help Baxter, but it wasn’t until she began studying and applying the science of behavior that Baxter’s behavior began to improve.

Kirsten began volunteering with the San Diego Humane Society as a dog walker and mentor to other volunteers.  In 2013 Kirsten and her husband moved to Europe where she began taking courses at the Institute of Modern Dog Trainers.  After moving back to the United States, Kirsten began her mentorship with Randi.  She is currently working toward her certification with the Certification Council for Professional Dog Trainers, the International Association of Animal Behavior Consultants and the Institute of Modern Dog Trainers.  She is currently volunteering at Homeward Pet Adoption Center.
