“Dr. Dumasia is one of my favorite doctors ever. She has one of the hardest jobs in the world, but she maintains the right balance of honesty and optimism. Her ‘bedside manner’ is second to none. She takes time to answer all my many questions, and trust me, I am a squeaky wheel. She knows I want to be aggressive, so I don’t have a recurrence, so she gives me options regarding my care. No one wants to be a cancer patient, but if you are one, you absolutely want someone like Dr. Dumasia taking care of you.”
