From my experience, Doctor Dawes is one of the finest pre-surgery physicians I have used in my lengthy history of cancer treatment. He is personable and engaging. His expertise is remarkable. I elected, with great confidence, to postpone surgery indefinitely after his prescribed tests, physical examinations and consultation. We reviewed a number of scenarios and alternatives, and he explained each clearly. I would undergo any future treatment without hesitation and with unhesitating confidence in any situation, including complications arising during surgery. It is easy to see why Stanford Medical has such a excellent reputation. Doctor Dawes and the entire staff are exactly the way medical treatment experiences should be. He exemplifies that reputation.

His operation on me last December for the colostomy has enabled me to function much better than before the operation including a return of appetite. I have a hernia now and he was very good about explaining about how to make a decision for a hernia operation.
