Considering how busy MSK was when I went, I got in immediately. After hoofing through 2 parking lots...never even had a minute to stop. Saw two nurses before the Dr. They were prompt and very thorough. The Dr. was 40 minutes till he saw me and literally spent 2 minutes. There was really nothing to go over as I have had this procedure before, I actually found it kind of humorous. MSK has been very prompt and courteous thus far. I have no complaints.
He made me feel like I was in great hands with him.
All very good. Let's just keep going down this path to success.
The consult was thorough, and he answered every question I had for him. It is clear that he cares about his work and patients. [patient name removed]
As always, it's a very comfortable experience when I have appointments. The doctors and nurses are always professional and personable. It's always a positive visit.
