    It was great! Very friendly staff

  • Dec 17, 2019

    She was great! Listened to us and explained things easy for us to understand.

  • Dec 13, 2019

    Courteous, friendly and listens to your concerns. Answers all questions about child/children and makes sure that you understand it

  • Dec 12, 2019

    I love Dr. Loh and OHSU Casey Eye Institute. They're always so helpful. Help us understand what we need to do and help us work on correcting my son's vision. Such a pleasure to work with such a great team.

  • Dec 06, 2019

    The provider is thorough but left many questions unanswered

  • Dec 03, 2019

    My appointment was very rushed. I didn't have any explanation on what he was possibly diagnosed with. And when I was asked if I had any more questions, I felt very rushed to answer any of those questions. I did not have a good one on one with the doctors, and it seemed like she just needed to get to the next patient, which I do understand, but that didn't help me with the news that I heard. I definitely needed more time to sit with the doctor, and I didn't get that. So, thank you.

  • Nov 13, 2019

    Friendly, informative, makes sure our questions are answered.

  • Nov 12, 2019

    The team seemed competent and thorough - but rushed. The hurried way they popped in and out of the room and conducted the tests was a little unsettling for my toddler. It would go along way to take a few seconds to help very little kids feel more calm and comfortable before diving right in. Even just asking the child if it's okay to touch them before touching would have helped my little one to be a bit less startled.

  • Nov 12, 2019

    She was kind, thorough and helpful

  • Nov 05, 2019

  • Oct 22, 2019

    The eye doctor we met with was very informative and felt like they took the time to talk us through what next steps were. I also felt like they truly cared about her quality of life and make her feel the most comfortable at the appointment. Thank you!

  • Oct 18, 2019

    Dr. Loh is very nice. She makes sure that, what she is saying that you fully understand, and that you agree with like if she has a recommendation, she makes sure that you understand why she's recommending it and if you agree with the recommendation. She's sure to take in any input that you might have into her decision, and she's really really good with my, my baby my baby's 1... and she's always really good to make sure that she's really sweet to her.

  • Oct 16, 2019

    Allison Loh she was on time and I didn't feel rush whatsoever while I was in the appointment with her her assistant took care of everything that there was to take care of his really fun. My son had a great time in there. I don't even think he knew what he was, you know, getting his eyes checked [Name] and the whole thing went really really well and Alison Loh was really warm and I really felt like she cared about my son's eyes, so that's great. Okay, that's it.

    Everyone was great with my son. He's 5 and they did amazing with how they interacted with him.

  • Sep 22, 2019

    Dr. Loh is always great with my kids. Is incredibly good at explaining things to the parents and genuinely cares about her patients. I feel supported by her and she knows some of the things that the kids need to do won't be easy but she helps you ease them into things and always says to contact her if anything goes wrong. We just love her and her very kind staff. They handle all 3 of my kids in a combined appointment amazingly well.

  • Sep 19, 2019

    I have had an amazing care through the Casey Eye Institute. My son has had a very complicated year with his eyes, and I've had nothing but the best care and I would recommend them to anyone. I'm very grateful that they are in Portland.

    Dr. Loh and staff are always amazing to work with. They truely are the best place to have your child seen. Dr. Loh always tells us directly and in easy to digest terms what we are looking at for treatment and ongoing care.

  • Apr 10, 2019

    The appointment went well and the provider help discuss how help improve my child eye vision.

  • Apr 02, 2019

    Dr. Loh is wonderful-very sweet, compassionate, efficient, & professional.

  • Mar 27, 2019

    My experience with the provider was very confusing. We had multiple nurses come in and dilate my daughter's eyes. We did not get a straight answer on what her zone or level was or care plan was. Everything was just very confusing. And it felt like they just wanted to get it out of there and move onto the next person. So maybe you guys should work on communication skills a little bit better. Thanks.

  • Mar 15, 2019

    I'm always really impressed by Dr. Loh she has incredible amount of patience and insight about caring for a child with Down Syndrome like our son and I am always feeling lucky that even though we have to drive over 2 hours in order to get to our visits with her, that I feel that they're worth the time. So, thank you very much.

  • Mar 13, 2019

    Love Dr. Loh and so does my son! She is so sweet and exceptionally good with children!

    It was great

  • Mar 08, 2019

    Very positive, nice people at check in, Dr was great with kids, great info

  • Mar 05, 2019

    Dr Loh is wonderful! She is always patient with all of my questions and we never feel like she is rushing off to the next patient. She is very thorough in her explanations and we trust her greatly!I do feel, however, that the front desk staff is lacking. It's always unclear if I should step up to the counter or not. And it's unclear whether I need to check out with them, or not. They don't seem to want to deal with people, would rather just wait for you to approach them. It never feels like a warm welcome.

  • Mar 05, 2019

    Dr Loh is amazing as well as everyone else in the Elks.

  • Mar 05, 2019

    Yes, I was very impressed with the doctor who seen my son, she was very careful. He did not want to talk about getting glasses. She was able to talk to him about that and help him understand. The nurse that helped us in the beginning was amazing. She had total ... control over what was going on in the room and my son cooperated with her very well, and she did a perfect job. Both the doctor and the nurse were amazing. Thank you.

  • Mar 01, 2019

    All of the doctors are professional and it makes me happy to go there. Everyone is very kind.

  • Feb 10, 2019
