Patient Reviews

  • "Very friendly and competent. Answered all my questions in a way that was easy for me to understand. I would love to see her again!"
      from Cathy 5.0 Stars - (2025-05-03)
  • "I was a little upset that it wasn’t Dr. Chu, as he is my doctor and the appointment was made for him. The other physician was fine, he just wasn’t Dr. Chu. Unfortunately, somehow, my blood work from three months ago was not in the system, He not being my physician, did not know this. My husband keeps copies on his phone of all of my Data from each visit, Therefore, he was able to show him the prior visits information. I am still very, very happy with the New York blood and cancer specialist. From the people at the desk to the people who take blood, everyone is wonderful. They are kind, always with a smile. I just would have liked to have known before I was in the room that it would be someone else who would be seeing me other than my own doctor😌"

      from Mary 5.0 Stars - (2025-04-30)
  • "I absolutely Love Dr. Guigova. She is so attentive, and goes above and beyond to make sure she sits and listens to every concern I have. My only issue is for the ladies at the front desk. They provide excellent customer service but it is so apparent there are major staffing issues. I’ve been here quite a few times now, and they are often left alone and it results in patients waiting in long lines for check ins and rebooking."
      from Kasey 4.0 Stars - (2025-04-30)
  • "Dr. Guigova is the absolute best! If I could give her a hundred stars, I would. She is not only a consummate professional with a wealth of knowledge, she is very caring, compassionate and always takes time to listen without rushing you out the door. The staff at the Ronkonkoma office is super nice and accommodating. I really can't say enough good things about this practice."
