    Very professional and competent.

  • Dec 19, 2019

    As I arrived I was promptly checked in and prepared for the time with the doctor. The tech for the scan and the medical assistant instructions were clear. A resident came in and spent quite a bit of time examining me and he also communicated clearly what was going on. Then Dr. Hwang rechecked and agreed with the resident and sent me on my way

  • Dec 16, 2019

    Always thoughtful, seem very knowledgeable, I know they have limited time with each patient but try to answer our questions.

  • Nov 30, 2019

    Yes, I had a very good experience with Dr. Hwang. He's very gentle and I never feel the shot, but I was very disappointed that they were out of eye drops went - for me to take home because that always helps me when my eyes get itchy an hour after I've been there. Thank you.

    Dr. Hwang is a very personable doctor and he seems to know his subject and I feel very confident in him.

  • Nov 24, 2019

    Very knowledgeable and gives excellent explanation of terms and procedures.

  • Nov 23, 2019

    When you are a patient at OHSU, and any department you feel like you have joined a big family. When you leave your appointment. There is a summary of what you have just done, or discussed, and then you have other appointments listed, if any of them are at OHSU. I really appreciate their care.

  • Nov 22, 2019

    Dr. Hwang is outstanding, he's been treating me for about three and a half, 4 years and he's taking me from legally blind to 20/30, 20/40 I think. He's excellent, he's great, he listens to what your concerns are and his treatment is excellent, I could not be any happier, thank you.

    Very caring and obviously very knowledgeable, but overbooked and rushed

  • Nov 15, 2019

    Dr. Thomas Hwang is an exceptional ophthalmologist and he performed the surgery for my (INAUDIBLE) about 14 weeks ago. I cannot recommend him highly enough and it's always a pleasure to be able to see him.

    Dr. Hwang is always thorough in explaining the current situation with my macular degeneration including results of eye imaging. I appreciate his competence with bi-monthly injections, always done with a minimum of discomfort.

  • Nov 14, 2019

    Dr Hwang is always great to work with, but I also wanted to share my appreciation for his front-desk person, Shelby Roether. She's amazing. She always greets me with a smile, remembers my name, asks me about my family, etc. She's super-professional and a real joy.

    Dr Hwang is an excellent physician who cares about his patients. He explains complex decision making and technical issues in terms to match the patient’s level of understanding and vocabulary. His demeanor is professional and courteous.

  • Oct 23, 2019

    Had a very long wait. Was there a total of 2 hours, and saw the doctor for approximately 5-7 minutes. I understand that some of this is necessary for the dilation of eyes, but it seems excessive and exhausting.

  • Oct 19, 2019

    Hey Dr. Hwang, has been my doctor for I say 10 years, and he's outstanding doctor, Upstanding person, very easy to to work with, very helpful. I would come back for treatment with him if I were overseas, which I sometimes do, does happen, and I just hope you can maintain him at your hospital for years to come. Thank you.
