Patient Comments

    Awesome staff and care.

  • Jul 28, 2019

    Honest, capable doctor. Friendly efficient check-in personnel.

  • Jul 10, 2019

    Everything was exceptional during my visit, the people that worked with me were amazing and very attentive to my needs. I would definitely come back here if needed, this was the best hospital experience that I have ever had. Thank you to everyone that cared for me during my visit!

  • Jun 28, 2019

    Well, I ... he was very good and I'm going to take care of the problem that he located at OHU.

  • Jun 28, 2019

    Everything is perfect with this doctor, thank you.

  • Jun 24, 2019

    Dr. Liem is an excellent physician who is willing to spend the time to answer all my questions.

  • Jun 24, 2019

    Dr. Liem was 45 minutes late in seeing me due to the person ahead of me being 30 minutes late. When I expressed concern about this, mainly that I was missing an event I wished to go to, Dr. Liem was extremely accommodating. He let me go right away and agreed to squeeze me in at the end of the day for a procedure that I would have had to schedule in another month. (I was still in the mindset of how things were done 5-6 years ago when a sclerotherapy procedure could be done the same day as the checkup appointment. They let me know that's not how it's done anymore while still honoring the old system one more time for me.) He more than made up for the 45 minutes that the office was behind and showed that even in a big system like OHSU, there is still room to be flexible and give patients more than they were expecting. I was also so impressed by Sherry (I think I'm getting her name right), the nurse who works with Dr. Liem. Because Dr. Liem accommodated me in this way, that meant that she had to stay late, too. She never showed even the least bit of annoyance by this. She was so friendly to me the whole time even though she could have started her weekend by then. I'd like to say a big thank you to both of them!

  • Jun 22, 2019
