Here is the URL to ASAP - American Society for Action on Pain. I just went there to see what they have listed for your state and seems like they are having some problems there and there are no longer any state rep's listed. I went to the Compassionate Doctors page and also could not find any listed for Colorado. You may want to go to the URL <A HREF="http://www.asappain.com/panic.html">Click here: panic</A> and see what is going on and if there is another way to get the names of the doctors.
I am going to write to someone that is from Colorado to see if she can help you find a doctor and will get back to you or she will get back to you.
Love,
Hell-yun
