About Maggie

Maggie Marshall earned her degree in Psychology and worked at the management level in the human services field until she got married and had children. She and her husband have spent the last nineteen years raising and homeschooling their two children.  In 2009, Maggie earned her Certification of Dog Training from Animal Behavior College and began her business, Maggie Marshall Dog Training.

In the past nine years, Maggie has built her business and improved her skills. In 2015, she earned a Certification of Professional Dog Trainer. Maggie comes highly recommended by her previous clients, the Clay County Humane Society, Jacksonville Humane Society, GREAT Rescue, local veterinarians and fellow trainers in Jacksonville. Maggie is a member in good standing of the Animal Behavior College Alumni, the Association of Pet Dog Trainers, the International Association of Animal Behavior Consultants and The Pet Professional Guild. In 2014 and 2015, Maggie's business won Angie's List Super Service Award for outstanding reviews. In 2016, Maggie became a Mentor Trainer for Animal Behavior College students and the official trainer of Woof Gang Bakery & Grooming in Fleming Island. In 2017, Maggie won Best Trainer in the City by Jacksonville Magazine. Maggie lost her mentor and close friend, Bob Hammesfahr, owner of Behavior Training for Dogs, in April of 2018. She and Bob maintained a professional relationship until he passed. He was the best trainer Maggie ever knew and was blessed to have learned from him and been given so much from him - he was a smart business man, a talented dog trainer and a true friend. Maggie keeps her training skills current by attending frequent webinars and yearly training conferences and now, she, is mentoring others to train dogs.

Maggie’s most recent accomplishments include becoming approved as an AKC Canine Good Citizen Evaluator, earning her Certificate of Behavior Consultant-Canine and opening her own training facility on the Westside of Jacksonville.


Maggie offers training programs for any pet dog issue from puppy house-training to dogs with bite histories; private sessions in your home, group classes at her facility and extended training packages. Maggie uses Positive Reinforcement as her method of training because she believes that we, as dog owners, should use our brains to teach dogs, not our brawn. Click on Services for specifics. Maggie’s methods are easy to use, obtain fast results and are fun for the dog and the dog’s family. Maggie uses her experience in the human service field to help her to really listen to her clients and find practical solutions to their doggie dilemmas.

Maggie's Methods

  • Teach and strengthen desired behaviors.
