Patient Comments

  • Jan 12, 2019

    Dr. Kemmer is very caring and compassionate. I was very ill with my 1st Chemo and she adjusted the dose for my 2nd Chemo

  • Jan 08, 2019

    Dr. Kemmer projected warmth and concern while clearly an expert in her specialty.

  • Jan 04, 2019

    Yes, Dr. Kemmer was very informed and very serious. She gave me all of my options and recommendations of what she believes I needed to do. She set me up for testing and it came back right away. And I appreciate that expedience on the results. She's very pleasant. And I had a wonderful experience with her.

  • Dec 29, 2018

    I think Dr. Kemmer is extremely thorough. I think she is, she tells it like it is but with a huge heart. I think she's extremely professional at the same time I'm impressed with the kindness that she has for the patient. So my experience has been great and I'm really blessed that I have her in my life.

  • Dec 22, 2018

    It was a very successful, comfortable meeting with the doctor. She had information that she was imparting intelligently and clearly. She gave me the patient information I wanted or needed. And the office is very well run. People, the nurse that takes you in and the people at the desk are all extremely courteous and pleasant. And of course, the doctor is too, and again, I say she knows what she's talking about. She's clear, very clear with the patient, and I felt very comfortable with her care and appreciate the time she took to be with me.

  • Dec 15, 2018

    She's very caring loving and she seems to really really want to help her patients out. I really enjoy her talking to her and she takes her time to explain. If I ask a question and very good doctor.

  • Dec 13, 2018

    I just wanted to say that Dr. Kemmer answered all my questions. She made sure that I didn't have any additional questions and she took adequate amount of time to listen to all my concerns, which is very appreciated. Thank you.

    Dr Kemmer is thorough and conscientious.

  • Dec 10, 2018

    Dr. Kemmer always comes in very, very prepared, having spent a lot of time researching my specific "happenings" and consulting other specialists. She is very comfortable, explains everything, and shows me the images in question. Really appreciate her preparation and demeanor.

  • Nov 07, 2018

    Extremely competent and compassionate. Always prepared. "Thinks outloud" to share her rational in developing treatment plan options. I feel that we are partners. I leave inspired to work hard at my self care goals. I traveled a total of 3 hours yesterday to see her. She's worth it.

  • Oct 27, 2018

    It's hard to know to talk like this into a telephone. She was knowledgeable, she was forthcoming, she was articulate in her sentences and description and professional opinions were easy to understand. I'm a fairly sophisticated at the Cimarron, I hate to use that word, but I've been around the block a few times and I've been too many doctors. I thought she was extremely clear. She was encouraging and polite and I had family with me and she was courteous to them. I felt very positive about her. Now, I don't know what I'm supposed to do, punch a... punch a number or something.

  • Oct 17, 2018

    Cordial and easily understood

  • Sep 27, 2018

    I am a cancer survivor. This was a one-year post treatment follow-up. My provider listened to a full update on my health, the odd occasional side effects I'm dealing with, and the emotion work of processing what I have been through.

  • Sep 20, 2018

    As usual, very thorough and answered questions with data based info.

  • Sep 18, 2018

I'm very pleased with this provider, excellent, and I give her a 10.

  • Aug 15, 2018

    I think Dr. Kemmer is just like any other oncologist she's basically following a protocol which is a recipe for anybody diagnosed with cancer regardless of situation and you can go to just about any oncologist and get the same care that's what I think.

  • Aug 14, 2018

    She is very nice and seems to know her discipline.

  • Aug 04, 2018

    Dr. Kemmer is the best Dr. on my team.. She is thorough, thoughtful, and always takes her time to go over everything with me. She takes the time to update herself before entering the exam room, and makes me feel comfortable with my prognosis.. I look forward to my visits with her, and feel that she offers the best care for me.

    Dr Kemmer is always thorough and on top of things. She is considerate and compassionate.

  • Jul 18, 2018

    This provider, Dr. Kemmer, is probably 1 of the finest ? physicians that I've had the pleasure of meeting and being involved with at Oregon Health Sciences. She's a very fine, caring lady, and didn't mind me asking her where she graduated in her graduate studies and her undergraduate, where she was living when she was young, and she and I, I felt like she was more my friend. She's very helpful and very kind, and she's just close to me and looks me right in the eye. I like that, I don't like people kind of shifting their eyes around. I wasn't very kind, I was in a bad mood that day because it was so hot, and ... *

  • Jul 14, 2018

    Dr. Kimmer is extremely competent. I thoroughly enjoy my visits with her as much as I can since I have cancer. She's very thorough, she listens to me, she takes enough time to answer questions, she even dealt with a medical situation this last time that wasn't involving cancer, it was involving a problem that I was having. I highly recommend her. Thank you.

  • Jul 13, 2018

    Dr. Kenner is very patient explaining the medical details of cancer to me, a person without any medical knowledge at all.

  • Jul 11, 2018

    Dr. Cemmer is a very caring oncologist who definitely takes the time to know her patients. I know she wants to do what is best for me as a individual throughout the rest of my life dealing with the possibility of reoccurrence and she's very willing to look at alternative ways to treat my future medical needs without necessary compromising my physical tolerance for pain and discomfort I'm experience from the after effects of chemo therapy and drugs *
