    Feb 01, 2023
    If was a very positive experience I felt that Dr Hansen is a special and dedicated person who has found his 'calling'. The initial introduction gave me a full understanding of the challenges the arthritis has created in my hips the medical solutions or options available to me and the solution I am choosing (surgery). Communication was excellent and my initial experience with Dr Eric Hansen was very positive and comfortable. Thank you!

    I wished that they could have informed me about my Physical Therapy options. Maybe inform me to schedule my PT early since there are backlogs for appointments.

    I didn't think of it at the time but it would have been helpful to get suggestions for exercises or things I could do to strengthen my knee/leg before my physical therapy appt over two weeks in the future
    Dec 02, 2022
    Dr Hansen is my Santa Clause. He is an Angel and a saint. Pursuant to my second hip he replaced for me I have experienced a pain free groin or core area ever since. This is the first time I have been completely pain free in that area for over thirty seven (37) years. I told him he saved my life. While this may be a slight exaggeration he surely did salvage what is left of my life and I am back out there baby!!!

    Nov 11, 2022
    Dr. Hansen was excellent in all respects and was able to answer my questions definitively which had not been true of an earlier provider at another facility (not UCSF).
    Nov 06, 2022

    At this time I am wheelchair confined. Trying to get myslef up on a procedure table and xray table were terrible. Why isn't there a hoyer lift or something similar for assistance? Having 3 to 4 people trying to pull me up was embarassing. If tables went lower I could have transferred successfully.
    Nov 03, 2022
    Everyone listened and included my needs in their responses. Very good interaction. Very professional but yet also very personal and warm.
    Nov 02, 2022

    I am very happy with the care I have received from Dr. Hansen. He replaced my right knee about five years ago and the experience of working with him and his team was great and the outcome was excellent. Based on this experience I was very comfortable with the arranging for him to replace my other knee.

    Jul 22, 2022
    Dr. Hansen was excellent from start to finish and clearly explained the knee replacement surgery process. He and his team met with me at the hospital before going into surgery as well as after to check on me. Dr. Hansen phoned my sister following the procedure to let her know all went well and when I would be out of recovery. It all felt personal and caring.

    No complaint
    Jul 20, 2022
    My experience with UCSF is that they see many patients and it feels like an assembly line. I am a cog in the fast moving wheel. Too many people are involved in my care and it is not explained to me in advance who I will be seeing for my care. The caregivers forget that I have not had this experience before and don't know the procedures or protocols. It's very frustrating.
    Jul 20, 2022
    I feel I am being provided with excellent care!
    Jul 20, 2022
    I think Dr. Hansen is a top notch doctor. I would recommend him 100%.
