    It's always a pleasure to spend time at OHSU's Imaging office.I've made some great friendships there. Always courteous and friendly, but above all , efficient. Going to some medical facilities may be traumatic. NOT here.The Vascular surgery department is outstanding. Even when extremely busy, as it is sometimes, the staff are helpful and always friendly. I rate them as tops in reception skills.Of course the Medical staff is excellent. I've known Dr. Liem for over 10 years and I regard him as not only a friend, but one hell of a physician.

    Dr. Liam is quite personable and knowledgable. He provides a great explanation of the procedure and summary of how he is going to perform it. He is also enthusiastic about answering questions.

    Great bedside manner: friendly, approachable and patiently explains everything about my condition, the treatment options available and his recommendations.

  • 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

    He was so excellent! Patient and great at explaining what would happen, potential risk and letting me make decisions. I really enjoyed my appointment with him!

  • Jun 22, 2019

  • Jun 17, 2019

    Very professional and friendly, Excellent service and explanation of care at the time of the office visit and follow up information.

  • Jun 14, 2019

    Dr. Liem explained what he was doing, what is t would do to take care of my problem and gave us a time for surgery. He was able to take care of it in the office bld. He explained as he did the repair I felt secure with him. Today Friday June 14, my lump is very small, and I have no pain at all. My heartfelt thanks to Dr. Liem for repairing the blood leak in my wrist and taking away all my pain.

  • Jun 13, 2019

    He's a great listener, takes his time, and offers his advise in addition to explaining the unknowns.

  • Jun 10, 2019

    Dr. Liem is very personable and attentive. He spent a lot*.

  • Jun 06, 2019

  • Jun 04, 2019

    I had a very positive experience from check-in, through time with the doctor, to check-out. Everyone was helpful, friendly and welcoming. The doctor left me with a great deal of confidence in his skills and plans for my care. It was all great!

  • Jun 01, 2019

    He listened to me and didn't imply that I was lying. He provided me with accurate information and didn't talk down to me. I felt comfortable and confident in his abilities. I will let him cut on me. ?

  • Apr 18, 2019

    Dr Liem has been very supportive and helpful with events that have arisen periodically from procedures. I might add here that I have been a smoker for 62 years of my 82 years. Due to Dr Liems influence and witty way of making me realize that I really had to quit smoking. I did quit after so many years. My quit date was Dec 15. So smokeless now for 4 months. Thanks to Dr Liem.
