Lia Marques: In 2013 Lia was hired as a senior dog trainer at Cesar Millan’s Dog Psychology Center. The 43 acre ranch is a place made for dogs by people that understand a dog’s needs. By working side by side with one of world’s most renowned dog behaviorists, her knowledge of dog psychology became second to none. The DPC is usually the last resort for some dogs with behavior issues and by working with these dogs on a daily basis propelled Lia’s knowledge immensely. By being able to rehabilitate dogs with severe behavior issues, she quickly became the go to person for other trainers to shadow and learn from. By combining her expertise of dog training and her previous career, Lia became the Dog Psychology Center Facilities Manager in 2014. That meant that besides coming up with training schedules for the various dogs, Lia also worked with the other animals at the ranch, helping to integrate many livestock animals like sheep, goats, horses and pigs with the dogs.

In 2016 Lia started working with Marley’s Mutts, creating and implementing Pawsitive Change which brings shelter dogs to prison for a 14 week period of inmate and canine growth. Teaching inmates the basics of dog psychology and having those inmates in turn help dogs has been truly life changing. The program is currently in four California prisons.

Lia is the owner and head trainer of A Dog’s Life with Lia, which offers personal in home training for both dogs and their owner’s. In addition she offers Board and Train to the most severe cases, helping to reset dogs to their calmer more balanced state in order for them to lead a more well adjusted life in their homes. She also works with several rescues in the Los Angeles area helping to rehabilitate and re home in need dogs.

Lia Marques is a professional member of International Association of Canine Professionals and a A.K.C Canine Good Citizen Evaluator.
