I have been climbing since about 1974. I have climbed in Yosemite, Devils Tower, Joshua Tree, Colorado, Oklahoma, Utah, Missouri, Arkansas, and Red Rock in Las Vegas.  Most of my climbing has been traditional with an emphasis on multi-pitch routes but now I do mostly sport climbing. I have competed in the 24 Hours of Horseshoe Hell 15 years in a row.  Years ago, I spent a lot of time locally at Cliff Drive and bouldering in Swope Park.  I have also set routes in multiple climbing gyms over the years. Professionally, I was a software developer before retiring several years ago.
