Dr. Samson Liu

Owner & Founder

My family and I moved from Hong Kong to Canada when I was 12 so I grew up with a strong work ethic of nothing is handed to you, you have to earn it yourself. After graduating from the University of Toronto, I accepted a scholarship to Northwestern University in Chicago. It was there that both my personal and professional journey began. I met my wife in dental school, started my first job with Heartland Dental in 1999, and for the past 18 years was an integral part of Heartland Dental’s growth from 13 practices, $13mm revenue in 1999 to 800 practices, $1.3 billion revenue in 2017.
