“Dr Delmastro always takes the ti...”

Dr Delmastro always takes the time to listen intently and address all of the issues that I present with. He is very concerned with my comfort during chemotherapy treatment, and makes adjustments to the plan every time that I present with a side effect that he believes is too serious. I have total confidence in him and the prescribed treatment plan. ... Dr Delmastro takes the time to answer every question, and is very thorough with his instructions during every single cycle of my treatment.
