In Denver, I strongly recommend Dan:

He's in Broomfield, which is a little closer to Boulder than Denver. Unless you're staying down near the Tech Center or that area, he is definitely worth the drive. He's a great conversationalist, and his massage is very therapeutic will sensual elements. As handsome as he is in the pictures, he is even more handsome in person.
