Hi, I'm Dan Twelker and I am riding El Tour de Tucson this Saturday, November 22nd, 2025. It's a 102-mile ride.

I will donate all proceeds to Volunteer Optometric Services to Humanity (VOSH)/International. VOSH/Intl supports optometry and eye care all over the world.

Right now, I am working with the Al-Ahliyya Department of Optometry in Amman, Jordan to develop the program and ensure the success of the students.
