Ok, Luis, I think (not positive) that I've found my old veterinarian for you. He has moved a bit further south, but still not far. (Lone Tree did not exist when I lived in Littleton/Denver ... Denver-metro is unrecognizable to me now!). ...
When/if you inquire, this man should be of advanced age if it is the same doctor that I used.

Please note that the service directory does list him as a "bird doctor" ... I do not believe he is an Avian Specialist and would recommend that you go to Dr. LaBonde for your avian needs.
Best of luck ... I can also ask my own veterinarian here locally for a referral ... he has a pretty good network of people he refers to. And, us country bumpkins have to sometimes venture into the big city for services when needed.
