    How was your appointment with Dr. Niesvizky?

    Feb 03, 2023
    Dr. Niesvizky is a world renowned hematologist who is thorough, approachable, thoughtful and caring. Equally important is that he doesn't suffer from an overdose of egoism. If you ask for a second opinion, like I did, he recommended the best available locally, or if you're willing to travel, like I was, I got a recommendation at the Mayo Clinic and at Dana Farber--not too shabby! After a consult I returned even more confident in my treatment plan. I'm not sure, but I think I started seeing Dr. Niesvizky in 2009 upon the recommendation of an acquaintance who had been on the staff of Sloan Kettering.
