Support your dog trainer by sharing your story

Cassie's passion for dog training began at Brown University while studying biology and animal behavior. She had the privilege of researching the behavior of a variety of species including elephants, vervet monkeys, African wild dogs, and more. The more she learned, the more she realized animal training was at a turning point, especially with the domestic dog. She began reading the latest literature, volunteering at Providence Animal Rescue League, and shadowing local behavior experts. It wasn't long until she fell in love with dog training and decided to pursue it as a career.

Upon graduation, Cassie moved back home to California where she immediately found a mentor, her now business partner Liv, and began training dogs both in the home and in group classes. After obtaining the hundreds of hours of experience necessary, she became a Certified Professional Dog Trainer (CPDT-KA) through the Certification Council for Professional Dog Trainers. Soon after receiving certification, she started her first company Cassie's Dog Training in April of 2017. While starting her business Cassie enrolled in the prestigious Karen Pryor Academy (KPA) Professional Dog Trainer Program, which she graduated from in 2018. She quickly outgrew Cassie's Dog Training and opened the bigger and better Clickstart with Liv in 2019. After collecting another 300+ hours of behavior modification experience, Cassie passed her Canine Behavior Consultant exam in November 2021.
