Former CAAVO member Steve Howells, 82, of Grand Rapids, passed away suddenly after working matches on Friday March 15 at the USA Volleyball Mideast Girls National Qualifier in Indianapolis.   Steve became a CAAVO member in 2005, the same year he earned his collegiate PAVO Basic Line Judge Certification.  He worked dozens of high school matches for CAAVO in our western area footprint. He remained a member until 2021, but continued as a MHSAA registered VB official, with this year being his 28th with them.  A memorial service is scheduled for Steve on April 13 at 2pm in Grand Rapids.

CAAVO Charter Member Dan Fuller

One of CAAVO's 32 charter members from 2002 has passed away - Dan Fuller of Grand Ledge.   Dan was a long time CAAVO member, working hundreds of matches at all levels, and going on to become a well respected NCAA Division I line judge later in his officiating career.  Dan retired from officiating a couple years ago due to a brain tumor that would eventually take his life recently.  Our condolences to his wife Barb, who often would accompany him to matches, and to his family, who supported him as a marathon runner and cyclist on hi 17 DALMAC trips. 



CAAVO Member Gary Merrill

It is with profound sadness that we learned that on February 3 CAAVO member Gary Merrill passed away after succumbing to a recently diagnosed illness.  Gary, who was 68 years old, and from Bay City, had been a long time member of our association, working hundreds of varsity matches throughout his 32+ years as a MHSAA official.  He was a trainer for our, and other, volleyball associations, and helped many of our 1500+ officials learn the art of officiating.   He emphasized that in addition to the written rules, there was a spirit of the rule to be correctly applied as well.   In 2011-2012, Gary served as our association's secretary-treasurer, and initiated the use of written member profiles for our members, a practice which continues in use today to document information critical to our network of assignors.

As a high school official, Gary recently represented CAAVO as a MHSAA State Final official, something he had aspired to do for some time prior.  As a high level collegiate official, he was frequently selected to work as a referee at the Midwest Region Volleyball Crossover Tournament, which features some of the best NCAA Division II universities in 10 midwestern states.  Gary also extensively officiated club volleyball, frequently working a dozen or more matches almost every weekend throughout the winter and spring months.

We have lost a very good official in Gary today, and many of our members will recall his willingness to mentor them to become even better.  Gary leaves his wife Julie, and his family at an all too early time.   

Gary joins our list of association members who passed away while still actively officiating:
