    Front desk staff are not that friendly and do not seem pleased to be working there but everyone…read moreelse is pleasant and helpful. Even those just taking blood/administering infusions and injections. The doctors are extremely thorough and will run every test they can think of to help diagnose the issue. I do believe the quality of care is high but there are definitely areas to be improved on starting with reception.

    Every time I go, I pay in person. Yet repeatedly, every time a few days later I am billed for what…read moreI just paid. Poor billing department. Also, every time I go, the secretaries tell me that my appointment is a different day/time. EVERY TIME I GO! So then I am left with waiting 1.5 hours for a bus ride home, for I cannot drive. They are unorganized, so I stopped going there and switched to Stony Brook Hospital Hematologists. I first tried seeing Dr. Yelda Nouri. She quickly stated something briefly. Then she rushed me out the door. I tried to ask some questions. She replied in about five words. Then she left the room to make more money by seeing more patients. She does not care about patient's health; works only for money. Dr. Nawaz is brilliant and kind, yet runs 45-60 minutes late. The Patchogue location has poor quality sensors for the water to turn on in the restrooms. The water turned on for only one second, off four seconds; on again for one second; then no more water at all from the faucet. I have never experienced such poor water sensors before. I almost began to bleed caused by so-called blood specialists. They seem to have no idea what causes eczema. My fingers within two minutes became cracked, peeling and almost bleeding from this location. Patients with eczema, beware. In general, NY Cancer and Blood Specialists has some good doctors, some not so good, and the quality of everything else is poor.
