Armstrong, 71, has served in his current position for 28 of the past 30 years, joining the franchise shortly after the 1983 baseball season under then-owner George Argyros. After an absence in 1990-1991 when Jeff Smulyan owned the team, Armstrong returned in July of 1992 when the current ownership group purchased the Mariners.
"Thirty years ago my family and I were given a wonderful opportunity to move to the Seattle area and become associated with the Seattle Mariners," Armstrong said. "We quickly grew to love this community and this team. Through all the good times and the not-so-good times on the field since 1984, the goal always has been to win the World Series. My only regret is that the entire region wasn't able to enjoy a parade through the City to celebrate a World Championship together.
"After much thought and reflection, it is now time for me to retire and enjoy as much time as possible with my wife Susan and our family. The recent deaths of several good friends have really had an impact on me and helped crystallize my decision. This was a very difficult, very personal decision, but I know in my heart that it's time to turn the page and move to the next chapter of my life."
Armstrong said he and his wife plan to continue to live in the Seattle area.
Born and raised in Louisville, Ky., Armstrong earned a degree in industrial engineering from Purdue University in 1964 and a law degree from Stanford in 1967.
Prior to his move to Seattle, Chuck practiced law in Los Angeles before running two large businesses in Southern California.
