Dr. Rapazzo was very direct and informative. Unfortunately due to an error she did not have my blood work related to the referral and was naturally a little confused due to this. She is very thorough and makes things clear which is very helpful.

Dr. Rappazzo honors and respects my decisions. I am in the waning season of my life due to cancer and my age. We have had candid discussions about quality of life and comfort measures. At this point, she allows me to ""lead the team"" and my family and I are grateful to her for allowing this dignity.
- 5 out of 5 starsReviewed on 12/11/2025
Dr. Rappazzo was very intuitive and informative. She made me feel at ease and was able to quell my fears of my illness. She is remarkably kind and sincere. [staff] was very polite in her approach and showed she had thorough in-depth knowledge of my affair. These two ladies are great at what they do and personally they cared for me to where I forgot I was at a hospital; rather I felt at home. I applaud them and hope they're able to touch countless lives in the same positive manner they touched mine.

Dr. Rappazzo is the best. Great listener, shows genuine concern. Knows her stuff
- 3 out of 5 starsReviewed on 10/30/2025
Dr. Rappazzo interacted with me as minimally as possible on the call. She joined a few minutes early and didn't say much. Quite frankly, the visit seemed to be a nuisance to her. This is an annual visit so not a burden in terms of her time and it is my only time to get any new information or developments concerning my condition. The call probably lasted around 8 minutes in total. I have not been sending her messages via MyChart or taking her time between the annual visits either.

This was a consult about my blood clots. Dr Rappazzo had obviously read my medical records and explained the issue (s) in detail. She then came up with a plan to go forward.

Since I had lost access to my usual laptop the same morning of the appointment, backup and Dr. Rappazzo were helpful in my navigating new devices and adaptable when Zoom audio did not work. We used cell to talk but could still see video. This visit was important to set pattern for aspirin taking in light of my past stomach ulcer. The pattern for phlebotomy and testing was set up at this time also.
