Jonathan Siegrist (born 27 August, 1985) is an American rock climber who is regarded as one of the world's most prolific extreme sport climbers, and who has redpointed, and made numerous first free ascents, of a large number of sport climbing routes at and above the grade of 9a (5.14d).^[1] Siegrist's breadth of experience at the world's most extreme sport climbing grades, means that he is often looked to for guidance regarding the grading of extreme sport routes in America.^[1] While principally known as a sport climber, he has repeated some of the world's hardest traditional climbing routes.^[6]
