    Dr. Baretti and [staff] were highly professional, thorough, thoughtful, and informative. Of the six oncologists I have seen since receiving a scary diagnosis two months ago, Dr. Baretti offers far superior diagnostic skills, scientific rigor, intellectual depth, and a wide-ranging perspective. She's also very nice and gracious.
