My experience with the Denver VARO was good, although I did not think so at the time my first claim was pending.
In retrospect, my claim dragged on for three years primarily because I did not initially submit the proper documentation to support my claim; consequencely, the first decision approved only a portion of the claim. The reconsideration/appeal is really what added a significant amount of time--that extra time could have been avoided if I had submitted complete documentation with my original correspondence.
Additionally, for the past seven years I have assisted a Korean War veteran in his travels to Denver for VA treatment and tests. In my opinion, he could not have received better treatment even if he had been treated by doctors at the Mayo Clinic or other highly regarded private entities.
