Patient Comments

  • Jun 05, 2018

    I am a retired nurse. They spoke to me as a patient and adjusted to my knowledge level very well. They did not speak "down" to me, nor did they expect me to know specifics I may or may not know in my nursing history.

  • May 07, 2018

    See my comments in prior section for Dr. Tsikitis. I am so glad to be in her care for my surgery.

  • Apr 30, 2018

    I've seen this doctor before so we have discussed my meds and health problem in the past. this doctor is fantastic! We did not get enough time to chat, but that was the system's fault. Doctors need to be permitted to sopend more time with each patient.

  • Apr 29, 2018

    I have nothing but praise for Dr. Tsikitis.

  • Mar 22, 2018

    The Dr. is very knowledgeable and explains things clearly in a compassionate way.

  • Feb 01, 2018

    I went in since I have had a recurring health issue after a previous surgery. I did not feel that the doctor was objective. She referred to my previous surgeon by his first name, told me "the past was the past" and I did not feel that she was able to give me an unbiased opinion on my medical condition.

  • Jan 25, 2018

    Doctor told me my cancer would defiantly 100% come back, how can she say something like that to me. She is not my Oncologist.

  • Dec 07, 2017

    Very confidence inspiring.

  • Nov 30, 2017

    All my care at OHSU is excellent. But Dr Tsikitis has to be in the running for the greatest physician who ever lived. She is wise, warm, respectful, expert, caring - what can I say, she's more amazing than any doctor on TV.
