OLYMPIA, Wash. – The key to a successful business is not only the bottom line, at least in the opinion of Washington Secretary of State Kim Wyman.

Wyman gave medallions to four businesses named the 2016 “Corporations for Communities” during a ceremony at the state Capitol Tuesday.

In the large-company category, Sleep Train was honored for supporting foster children and non-profit organizations.

Republic Services received the award for a food drive and raising fund for a memorial at Monroe High School for students who have lost their lives in service.

Recipients in the small-company category included Birch Equipment, for its work with charities, and U.S. Martial Arts Center, whose students raised more than $75,000 for less fortunate children in Olympia.

Jason Lee, one of the owners of the taekwondo academy said having the students help the community helps the students.

“Self-defense is not only about punching, kicking, blocking, and takedowns. It’s also about building a strong foundation,” said Lee. “And that foundation instills not just confidence, focus, discipline, and respect, but also self-esteem.”

Before one of his students can be a black belt candidate, they must spend a full day volunteering at the Thurston County Food Bank.
