Possessing the ability to officiate freestyle, folkstyle and Greco-Roman, David Errett truly made his mark on the sport of wrestling.

A licensed official for folkstyle wrestling in Indiana for 20 years, he obtained his national license from the USA Wrestling Officials Association in 1988 and received his international license from International Federation of Associated Wrestling Styles (FILA), which is now United World Wrestling, in 1990.

Errett officiated 25 World Championships, 18 World Team Trials, six Olympic Team Trials and 13 Armed Forces Championships. He was named USA Outstanding Official for the Junior Nationals in 1991 and was the USA Wrestling Official of the Year in 1996.

The USA Wrestling Officials Association presented him with the 1997 Mort Geller Award, which is given to an individual who has demonstrated outstanding officiating skills on the international level and who is recognized as an outstanding clinician on the national level. The organization also honored Errett with the 2013 Phil Portuese Award, presented to a referee who has gone above and beyond the norm to teach the art of officiating. FILA/UWW awarded him its Golden Whistle Award in 2003 at the Greco-Roman World Championships in Paris, France.

Errett taught business at Martinsville (Indiana) High School for 40 years. He was an assistant football coach for 14 years, an assistant wrestling coach for 11 years and the head wrestling coach for 20 years. He led his teams to third-place finishes in the state tournament in 1989 and 1991 and coached three individual state champions and four state runners-up.
