Pediatric Occupational Therapy
Meet the Team

Matthew So (MOT), Reg. (BC)
Matthew earned his Bachelor of Kinesiology from the University of British Columbia in 2019, followed by his Master of Occupational Therapy, also from UBC, in 2021. He is a Registered Autism Service Provider (RASP) and a member of the College of Health and Care Professionals of BC (CHCPBC).
His passion for working with neurodiverse children and youth took root as a Special Olympics coach and occupational therapy assistant at private pediatric clinics, where he saw firsthand how play-based therapy transforms a child's participation, engagement, and connection. Matthew brings a relationship-focused, strengths-based, and neuro-affirming approach to his work, aiming to empower clients and families as they work toward their goals together. He strives to create a safe space where children can be their authentic selves and feel appreciated for their unique identity and strengths — and he firmly believes therapy should always be fun, because play is one of the most powerful tools for learning and growth.
Growing up in Vancouver, Matthew has always loved the outdoors and is constantly on the hunt for his next hike or camping trip. Outside of work, he enjoys running, playing badminton, and walking his cat Pebbles (pictured), and he's a devoted Canucks fan who never misses a game, playoff drought notwithstanding. Matthew is fluent in both English and Cantonese.
