    Dr. Roller familiarizes himself with my current medical status BEFORE entering room (I receive treatments at Gilbert location under auspices of another oncologist.) He always has a smile on his face, a positive discussion of my treatments and a willing listener to any concerns. I also like the outgoing cheerfulness of intake person, Mira. She asks about family members when they aren't with me, a very caring team. We are getting to know the new nurse and feel she will be an asset too.
