XENDURANCE Founder: Sandy Kellin

Jesse Owens was recognized in his lifetime as "perhaps the greatest and most famous athlete in track and field history"

Pictured to the left of this Olympic flag is Sandy Kellin, Founder of Xendurance. Sandy’s USA Bobsledding pursuits in 1980 led him to a meeting with Jesse Owens. Jesse supported Sandy’s efforts in going for Gold through fund raising and providing much needed international travel contributions.

When Jesse sadly passed away, Sandy was contacted to provide an Olympic Flag to honorably drape the casket when Jesse was laid to rest in the Arizona State Capital. This precious flag now hangs in the corporate offices of Xendurance, located in Scottsdale, AZ.

To share this memory is nothing compared to what Jesse Owens shared with the world. We must never forget what Jesse did for all sports and for the giving nature he gave to everyone who reached out for help.
