    Dr. Shreve is an amazing. I look forward to my visits with him because I learn so much about my cancer and how it is being managed, but he also listens to me, answers all my questions and explains the why behind the treatments. In addition, he arms me with suggestions/prescriptions to mitigate side effects so I'm ready and they aren't so scary if/when they occur. I feel SO supported under his care. I am strengthened at each visit.
