Carl Mason

Chief Operating Officer

Since I was old enough to walk, I ran around construction projects of assisted living facilities that my father, Chris Mason, built. My father has exposed me to the satisfaction you can receive from helping a senior enjoy the best years of their lives. From building elaborate train sets in the common areas to sitting down and having a one-on-one conversation with a resident. Chris has taught me that it’s the little things that make the biggest difference.

After graduating from George Fox University in 2013 with a Bachelor’s of Science in Athletic Training I worked as the Head Athletic Trainer at Canby High School in Canby, OR. I still use my degree as a personal trainer for multiple gyms as a hobby helping friends and family stay healthy. I started working for Senior Housing Managers in the summer of 2014 as an Operations Analyst, working on day-to-day activities. I became a certified assisted living administrator in Oregon after completing the required course work in July of 2014. In 2019 I was nominated for a year long Future Leaders Program through AHCA/ NCAL by the State of Oregon which excelled my understanding of what it takes to be a leader in the long-term care world. After 5 years of running the operations, I was promoted to the Chief Operating Officer in 2021. I stay engaged with multiple committees including the OHCA’s Legal Committee, ALF/ RCF Council, Independent Owners Council, and NCAL’s Policy and Finance Committee.
