The 6-foot-4 senior outside hitter and right-side hitter tallied 396 kills and 381 digs this past season, leading the Crusaders (35-1) to the Class 6A state quarterfinals. Decker also recorded 45 blocks and 36 service aces while posting a kill percentage of .475 and a hitting percentage of .353. A First Team All-State selection, she concluded her prep volleyball career with 925 kills.
Decker has maintained a weighted 3.91 GPA in the classroom. She has signed a National Letter of Intent to play volleyball on scholarship at the University of Santa Clara this fall.
Decker has volunteered locally with a homelessness advocacy group and served a mission trip to Nicaragua where she helped build a schoolhouse. She has also donated her time as a school ambassador and to the YMCA of Greater Seattle. "Kathryn is a threat from every position and hitting from anywhere in the front row," said Carol Lambert, head coach of Southridge High. "Her command of her shot selection is what makes her so dominant."
