Marc Wong, CTC
Marc has been an animal lover for as long as he can remember. As youth growing up in Singapore, he would often return home with stray animals in an attempt to care for them. After a successful 17-year Engineering career, Marc returned to his love of animal care by starting a successful home-based doggie board, train and daycare which was featured in PEOPLE magazine.
Considering himself a "Crossover" trainer, Marc chose to focus exclusively on force-free training techniques after being exposed to the writings of Susan Friedman, Ian Dunbar and Jean Donaldson. He would later go on to enroll in Donaldson's 2-year program at the Academy of Dog Trainers, eventually graduating with honors and obtaining Certificate in Training and Counseling (CTC). His specialties are "Lure-Reward" training as well as Desensitization and Counterconditioning of fearful / aggressive dogs.
When not teaching classes at PHS/SPCA, you'll find Marc volunteering as a teaching assistant at dog shelters around the San Francisco Bay Area or simply enjoying spending time with his (4 human + 2 dog) family.
