    He has been an excellent doctor and I wish him the very best in retirement! Really listens, really cares!

  • Dec 18, 2019

    I love Dr Pffiefer, he listens and interacts with my husband and I, have never felt rushed, and he makes eye contact with my husband and talks to him. So often, in life because my husband has dementia and it is hard to understand or know what he’s saying people will look at me for answers instead of trying to talk with my husband. Dr Pffiefer you will be missed, but enjoy your retirement.

  • Dec 17, 2019

    Dr. Pfieffer is thorough, and listens very well. Always makes me comfortable in his presence and following his advice.

  • Dec 10, 2019

    I was running late for my appointment, and called in to let them know. I waited a bit more than usual but really appreciated being fit in. I am so sorry (for myself) to see Dr. Pfeiffer retiring. He is a great doctor. I wish him all the best on a well deserved retirement

    Dr. Pfeiffer has been my doctor for about two or three years. I find him very gentle and nice and thorough I was very afraid having Parkinson's and he made me feel much better about it. I couldn't recommend him any higher. Thank you so much.

    MD P = knowledgeable, informative, helpful & supportive

  • Sep 19, 2019

    Dr. Pfeiffer pays attention and is interested and has excellent feedback and it's very appreciative rather than having to be so rushed as in so many doctors offices. Thank you.

  • Sep 19, 2019

    Experience provided with Dr. Pfeiffer was excellent. He has always been excellent. The only problem we have is the fact that we're always at least a half an hour late before the appointment starts. I will say he does take time with you and works with you until the end. So as a whole it's fine, but do wish it'd be possible to take people more on time instead of having to wait.

  • Sep 17, 2019

    Greatly appreciate my doctor's efforts! I will sorely miss him as he retires. Good guy.

  • Sep 17, 2019

    Dr. Pfeiffer is a great doctor. Compassionate and truly cares about my husband and the struggles he goes through with Parkinson’s. He patiently listens and is very thorough with his examination and provides clear explanations for him to understand, as well to me, his caregiver. Could not ask for a better doctor.

  • Sep 13, 2019

    Dr. Pfeiffer has been a very supportive and caring physician, and I am sorry that he's going to be leaving and going into retirement. I care about him a lot. Thank you.

    Dr. Pfeiffer is one of the most considerate and best listener that I've ever had. I appreciate his experience and his knowledge, especially his welcoming, concerning attitude and his willingness to explain everything to some, I'm sure stupid questions that I ask I would recommend him to anyone. Thank you.

  • Sep 12, 2019

    My experience as being a patient, being a patient of Dr. Pfeiffer's is excellent. From the beginning to the time he became my doctor to the time I saw him just about a week ago he's very thoughtful and goes out of his way to, to help patients with their prescription and also in just general discussion about your condition and answering questions and so on and very patient and very though and really one of the best doctors, specialist I've ever had.

    Dr. Pfeiffer provided me with all the time i needed. Answered my questions in his gracious in the process.

  • Aug 15, 2019

    Hello, Dr. Pfeiffer is fantastic, but the directions on from the construction on getting to it from the parking lot to the building or to his office is very difficult at best. It seems like there's a lot of signs missing along the way and including signs that inferred that only employees are supposed to go in the area where the elevator is. Anyway, it would be helpful possibly to have someone that would direct customers or your patients to the right area from the elevator. It's all I can think of. Thank you.

  • Jun 29, 2019

    Hi, this is [Name] I am giving a little bit of feedback for Dr. Pfeiffer. I wish Dr. Pfeiffer and other doctors at OHSU would be a little more involved or willing to help people find out when they have issues that aren't easily diagnosed. It's frustrating for the patient to not feel like they have somebody on their side.

  • Jun 28, 2019

    I found Dr. Pfeiffer very sincere and he provided a lot of time with me to understand my situation and....and also the best care possible.
