Dr. Daniel R. Possehn began with Cheyenne Radiology Group in 2005, after finishing a neuroradiology fellowship in California. Although Dr. Possehn can usually be found with a cup of coffee in his hand, don’t try to offer him a mug of instant joe—he’s more of a coffee connoisseur than a caffeine junky. When he’s not at work or traveling to remote destinations, he can be found jamming on the drums or enjoying a walk with his wife and their four-legged child Bear, a golden retriever.
