"I am a patient of Dr. Rossi at the Cancer Center and am currently on my 18th day of 22 days of radiation treatment for prostate cancer. I am 75 years old, have experienced cancer previously and have been in numerous hospitals and cancer centers. My experience at the Calaway-Young Cancer Center has been extraordinary in every way. From the smiles on everyone's faces when they greet you, to the navigating care, to the Dr's, to the follow-up, the physical beauty of the facilities, the state of the art equipment and complimentary services, takes this to a whole different level of health care. Myself, my wife and my mother-in-law have all told everyone we know in the Vail Valley, where we live, that working with this facility makes an unpleasant medical ordeal as pleasant as an experience of this nature can be. I've had several surgeries at [another facility] and there is just no comparison to the care."

"Saw Dr. Rossi when he was in Atlanta. He is one of the best!"



"Greetings Dr. Rossi, I don't know who hires and trains your employees but I have to say, I have never in all my travels, through 20 countries in this world and every state in the United States, I have never, ever met such Quality, Caring and Professional people anywhere. From my first contact as well as my follow-up, not to mention the oversight of the nurse navigator and her expertise and watchful caring, as well as your personal nurse, to integrated therapies, who ever does your hiring and training, it is the best place I've ever been in this world- Congratulations, keep it up!!! One last comment. In my quest to find the best treatment I was told by three different doctors that you were unquestionably the BEST! In my experience in working with you thus far you have surpassed what your colleagues have said about you. I don't know if you have any idea what that does emotionally and realistically in a patient's heart, but I can tell you it adds to the healing - Big Time! I say two thumbs up to the Calaway-Young Cancer Center and Valley View!"
