I was first exposed to Robert's Rules of Order in 1989 as a 15-year old volunteering in a youth service organization during high school in North Carolina.
I didn't realize until much later how phenomenal that organization was. Hundreds of high school students around Greensboro and Guilford County, NC would organize and run numerous programs throughout the year, including a Carnival fundraiser that would bring in $80,000 or more to help underwrite numerous other community service programs. The Greensboro Youth Council had their own office and a few adult advisors, but the students elected their own Board, as well as Chairmen for each of the dozens of projects it organized throughout the year. I personally logged over 2,000 hours of volunteer community service during high school.
I've never found another youth-run organization that operated at that level. The handbook and weekly meetings relied on a deep familiarity and understanding of Robert's Rules of Order, and it was a fundamental part of training.
Since that time, I've used my knowledge of RONR to help many nonprofits in dealing through difficult situations. I've developed a knack for Bylaws (writing and revision) as well as understanding gaps, risk management, and active problem resolution.
To this day, I continue to find great use of parliamentary procedure in my nonprofit work, on public boards and committees, and in corporate organizations.
