    The coordinated aspect of this multidisciplinary visit was so helpful. Both doctors I saw asked how I was doing almost immediately upon entering the room, and their questions felt genuine; that put me at ease. They were patient, thoughtful, candid, clear...all things I needed in that moment and will need going forward.

    I'd like to clarify why I stated No to a question that was asked re: test red. Tests that are ordered are reviewed with the provider when there is an f/u appointment. If tests came back with concerns then the provider would call immediately to set up an appointment immediately so that we could discuss the finds in order to develop a plan of care. I as the pt have no problem with this practice as if all is good no need to waste the providers time.

    Dr Rosenstock is a knowledgeable and caring medical oncologist. He provides important information about the rationale for treatments and gives encouraging support. In addition he always ends the visit with a reminder to call with any question or concern. My only concern with my visit to the cancer center is that here was no scheduler to set up my next visit. In the past, I have always left with my next appointments on my calendar. I have not yet heard from anyone about possible dates for this important follow - up.

    Assuming a care provider is a doctor, I only saw her once on a zoom call before my first appointment. I had several appointments after that and didn't see her even once. I only saw nurses and I was very disappointed in not seeing the doctor at all. The nurses seemed knowledgeable, but I would really liked to have see the doctor. I asked once where the doctor was and was told that she isn't here today. If that is the usually routine I would like to have known when she was there. When I made my first appointment I was told the appointment was with the doctor, but I never saw her that time, or at any of the following appointments. I'm not happy with this.
