Rexanne Hill
secretary
email: secretary@gkcoa.org
My name is Rexanne Hill, and I am excited to serve as Secretary of the GKCOA Board. My lifelong passion for sports and officiating, combined with my leadership and organizational experience, makes me well-suited for this role.
Growing up in Independence, Missouri, I attended St. Mary’s High School, where I competed in volleyball, basketball, and track. I also played USAV club volleyball, gaining early experience in officiating. My commitment to giving back to the sports community began as a youth basketball referee for the Independence Youth Athletic Association (IYAA). I later earned a Division I volleyball scholarship to the University of Missouri - Kansas City and continued officiating summer league volleyball at Raytown South High School throughout college.
Professionally, I served as a history teacher and coached volleyball and basketball for eight years at Raytown South High School before transitioning into administration at Lee’s Summit North High School. While I temporarily set aside officiating to focus on my family, my passion for the sport brought me back to the court. For the past four years, I have officiated middle school, high school, and college volleyball, earning increasing postseason opportunities each season.
As Secretary, I bring strong communication, organization, and leadership skills to the board. My background in education and administration has equipped me with the ability to manage records, coordinate effectively, and support the needs of our officiating community. I look forward to the opportunity to serve and contribute to the success of GKCOA.
