Patient Reviews

  • "Excellent, professional, patient manner"
      from Dwight 5.0 Stars - (2025-02-09)
  • "(Translated by Google) Very good service and answer to all our questions (Original) Muy buen servicio y respuesta a todas nuestras dudas"
      from Yudenis 5.0 Stars - (2025-02-07)
  • "Beside asking if I'd ever with him before at the start of every visit, he skims your chart in front of you, and often can't locate test results. Had no regular schedule for scans, and having 2 primary cancers would only get scans of a single area. He also asked my ethnicity, but if I was Russian, then that's OK. Was that a joke? The kind I see in his other reviews about his 'wonderful sense of humor?' I finally told him that I no longer trusted him to be my oncologist, and he asked what he could do to fix that? I demanded a PET scan. Well, I took that PET scan to my new oncologist. What a difference!"
      from Reviewer 2.0 Stars - (2025-01-31)
  • "I arrived for my appointment a half n hour early and they got me started early! No wait time, maybe a little bit, just enough to fill out all forms, the receptionist was very nice and polite, all nurses were super friendly, shout out to KI (aka “Church Flower”)who happily took my blood, Dr. Cibianu was also very informative and professional, such great place, I definitely didn’t feel like I’m at the doctors office for sure!"
