Mendes was born in Visalia, California in 1969, but later moved to Turlock. He started riding bulls at the age of five during a family ranch branding session. Scott’s grandfather, Frank Mendes, was a charter member of the predecessor Cowboys Turtles Association, where he competed at Boston Garden and Madison Square Garden in New York City. His father, Alan Mendes rode bulls, but mostly stayed close to home and never really ventured too far from the family ranch. Scott was surrounded by athletic talent within his family. His older brother Mike played football and younger brother Tony also rode bulls. Both Scott and Tony qualified for the PRCA’s National Finals Rodeo and PBR World Finals. Scott, who was a co-founder of the PBR, qualified for the PBR World Finals in 1994 and 2001, the latter of which was the only year in which he and Tony qualified together for a world championship event. Mendes moved to Nevada with his father after his parents' divorce. Mendes won Nevada State High School bull riding titles in 1985 and 1986. He also qualified for the High School National Finals. In 1988 he finished 2nd to David Berry from Oklahoma for the PRCA bull riding rookie after only having his card for two months. Mendes' breakout season came in 1991 when he won the short round and first place in the average at Cheyenne Frontier Days on the 1992 PRCA Bucking Bull of the year, "Rocky", owned by Dan Russell. During his professional career, he qualified for the NFR five times, the Bull Riders Only World Finals twice and the PBR World Finals also twice. He also competed in Championship Bull Riding. Mendes reached the pinnacle and milestone of his bull riding career in 1997 when he won more money than any other bull rider in the PRCA and was crowned the World Champion for said organization that year. His last known professional bull ride attempt was at a PRCA rodeo in Sonora, Texas in mid-August of 2005.
Personal life
Soon after the death of his fellow bull rider and good friend, Brent Thurman, Mendes became a "born again" Christian. He responded by wanting to spread the word amongst many of his fellow rodeo cowboys. He and his wife, Angel, are founders, owners and operate Western Harvest Ministries. The national headquarters is an outreach ranch located in Weatherford, Texas. It serves as the foundation for a Christian bull riding league and training camp. Mendes met his wife Angel during his rise to fame riding bulls. He has two sons, Kaden and Kolten, and a daughter Jorden. His children also exhibit various rodeo talents.
Mendes is the Pastor of Western Harvest Ministries, and founder of several Christian organizations building cowboy character for youth. He also travels throughout the country ministering in several churches, and is a corporate motivational speaker. He has made several television appearances on worldwide Christian stations, such as Trinity Broadcasting Network.
