Glendon began officiating football in 1983 while going to college in North Dakota.  The first day he walked on the field, he worked a junior high game in the afternoon & a varsity game that night.  He moved to Arizona in 1984 & continued officiating football, as well as basketball & volleyball.  He officiated at all levels & gave of his time & knowledge to mentor new officials, as others (such as Lynn Courter, Tom Matesic & Ed Burke to name a few) had done for him.  In football he worked every position at the varsity level before becoming a varsity crew chief in 1996. He was also an official with the AzFL from 1997 thru 2002.

Glendon joined the board of the Central Arizona Football Officials Association (CAFOA), the predecessor to the Arizona Football Officials Association (AzFOA), in 1997.  He immediately got involved with the formation of the Ed Trexler Football Camp & became an instructor for new officials, making a difference right away.  Between camps, he compiled information from the previous camps & produced a professional quality packet for future camps.  As a result of compiling this information, he also produced a varsity pregame booklet that he willingly shared with numerous crew chiefs throughout the years.

Glendon broke new ground in Arizona with the creation of the mentor program.  He took a feedback mechanism he had developed for non-certified officials he worked with on junior varsity games & rolled it out across the valley.  The mentor program provided a consistent mechanism to help officials improve & documented the steps necessary to progress from one level to the next.  The initiation of the mentor program removed the ambiguity that existed previously.  The program expanded beyond Arizona to other states & an overview was also presented at the 2001 NASO National Convention by then AIA Commissioner of Officials, John Reigar.  This program will live on & is a lasting legacy to Glendon’s willingness to give back to a sport he loved.

Glendon’s most memorable football moment took place on October 25, 2001, when he officiated the Cox “Game of the Week” between Hamilton & Highland.  It wasn’t his favorite moment because his crew was on TV, nor because of the schools involved, but because his son, Brent, was at the game celebrating his 9th birthday working as ball boy.  A lasting memory was created for father & son that night when Brent was shown on camera & highlighted by the announcers.

Glendon retired following the 2002 season after 20 seasons on the gridiron.  He continued to be active post-retirement in the mentor program by observing officials while attending his sons’ high school football games.
