Patient Comments (1)
Dr. Mascarenhas makes me feel confident about the treatment of my rare blood disease. He is incredibly knowledgeable about the research in the field and seems to take joy in the science, but he also interacts personably with me as a patient and explains the issues clearly. Finally and importantly, he is incredibly responsive and helpful when I ask an urgent question, never making me feel like my health is an imposition.
