Since I live several hours away from CC, this video visit was ideal and though not as personal as in-person, it felt personal because of the care and warmth of the provider. A great visit!

Marie has been a godsend. She is so caring and compassionate; takes the time to listen; and explains things so clearly and easily. She has made my chemo journey so much easier than it would have been without her. I'm incredibly grateful to be in her care.

Marie was fantastic! She really listened to me, didn't rush me, and took the time needed to both answer my questions and make sure I knew what to expect for treatment. She really helped make this nerve-wracking day a lot more comfortable.

The NP that I had a visit with was extremely attentive to my needs and concerns focusing on things that I feel the doctor does not address. I would absolutely have another visit with her.
