    Feb 27, 2025
    Dr. Chee was mistaken about how I felt about the procedure that was suggested. She assumed my wife's attitude was the same as mine, (which was the exact opposite). But she understood what I am doing and trying do to get my problems resolved.

    Feb 21, 2025
    Dr. Chee is AMAZING! She is always available to answer questions and makes her patients her #1 priority! Her happy, positive and caring disposition is comforting and calming! Her follow-up is fantastic as she gets back to her patients in a very timely manner, even in the midst of her busy schedule and patient workload, which is comforting as test results can be hard to clearly understand for patients. This is one of her many OUTSTANDING qualities!

    Aug 16, 2024
    Dr. Chee is so very caring and kind. She explains my illness and symptoms so understand why it is not time to begin treatment. She also explains why specific symptoms are, or are not related to the CLL and helps me tremendously. CLL is very complicated and hard to understand, but Dr. Chee takes the time o answer my questions and to explain what is and what in not CLL related. AND...I do read as much as I can about CLL but as I said, it is a complicated disease to understand. I thank God I have Dr. Chee as my oncologist/hematologist.
    Aug 13, 2024
    Dr. Chee was very attentive and she paused after explaining and asked if I had any questions or concerns that she needed to clarify. I found that very helpful because it eased my anxiety.

    Dr Chee is the consummate professional.
    Mar 17, 2024
    Dr. Chee always listens to me and explains why or why not my symptoms are related to CLL. So many symptoms are similar and I don't know when my symptoms are part of CLL or are because of something else going on in my body. It really helps me understand what is CLL related. My one issue is there are limited treatments for Leukemia and it doesn't help to treat early. I am confident there will one day be a cure! You have made great progress in treating leukemia, so I have lots of hope for the future. Also my CLL is the slow growing kind, so I expect to have many good years of life a head of me.

    Aug 22, 2023
    For cancer patients, I think it would help if someone played the role as a quarterback. I wasn't sure about what I should do next in the process after the completion of the first set of chemo. But all of a sudden I need to contact the surgeon to let him know I'm going to be finished with the fourth round. And my oncologist had to put in an immediate order for a CT scan to ensure I would be able to get to surgery in the next 4 - 6 weeks. Sometimes scans are fully booked many weeks out and may delay the time a patient can get to surgery. It would be good if someone played a lead role in the next steps I should be taking in the process and the timing of when these things should take place. Or better yet playing a role in initiating the next steps between the surgeon, oncologist and coordinating the scans that would need to take place after chemo and before surgery.
    Aug 19, 2023
    If I could mark higher than 5 I would!

    Jul 23, 2023
    Dr. Chee is top notch. I highly recommend her.
    Jul 20, 2023
    Dr. Chee is awesome! When she comes in to see me, she has already looked at all my blood tests and knows exactly what is good, or concerning. She explains her concerns and what she is watching for, she also helps to separate out what is CLL and what symptoms might be related to some other issue, or comorbidity. I am grateful because how can a patient know if CLL is causing their symptoms or not, so many symptoms are similar. I have no idea what symptoms are related to CLL or something else. Dr. Chee is very clear about what is and is not CLL and that helps me better understand what is going on. My only wish is that Dr. Chee was not so very busy, she spends time with me but she talks so fast, it takes me time to figure out what she is really telling me. This is not her fault, I am not in the medical field so it takes me time to understand all she shares with me. I tell you I feel blessed to have Dr. Karen Chee managing my CLL. She is EXCELLENT!!!! I hope I stay in "watch and wait" for years to come, but if I don't, I know I am in good hands...
    Jul 20, 2023

    My appointment with Dr. Chee was an annual wellness check. She addressed this as well as a new health issue. In doing so, she was reassuring, thorough in her explanation of the issue, next steps and plan. She took the time to be sure I understood the concern and plan. Dr. Chee is an excellent, knowledgeable clinician who is friendly, active engages, and shows high caring capacity. I would recommend her to friends and family in need of an oncologist.
