Everything was excellent. Thank you very much.
August 21, 2026
I think overall she was a lovely lady, but I did have some concerns about some ultrasounds. She said she couldn't pull them up on the computer. And I'm thinking, well, that's pretty odd. You're a PIH and I had them done to PIH, but I had them done over two weeks ago, so they should have been able to be pulled up to the computer. So I was very dissatisfied with that. I didn't feel like she tried very hard to try to find the images of my ultrasound. But overall, she was a nice lady and she did listen to my concern. And yeah, I would highly recommend her. I was just a little disappointed in that. Thank you so much. Bye-bye.

I felt very comfortable with all the staff. Starting with the Dr Kim and the whole friendly staff.
August 07, 2026
In general, the whole office was extremely pleasant. The doctor was incredible. He took the time, asked questions, listened. I really enjoyed the experience based on how she was. Overall, excellent. I think for any of these I do scheduling in general, although this one wasn't too bad, was the hardest part. But other than that, everything was great. Thank you.

First of all, my first number was wrong. It was supposed to be a four, not a two. Dr. Kim, amazing. Her staff, amazing. If her staff is amazing, that means the team leader is amazing. Amazing, amazing, amazing, amazing. Truly a godsend. So recommend them to everybody and answer the prayer. Thank you so much, Katherine Kim's team. God bless you. Bye-bye.

He was very professional. I liked the way he is. Thank you.
July 23, 2026
Dr. Kim listened to my concerns carefully and provided advice and options as to how to address my health problems. I felt respected and heard. I trust her.
July 21, 2026
She's very nice. She explains everything very thorough, which I appreciated. And she's one of the best doctors I've had.
July 13, 2026
I am beyond impressed with the professional service and care that Dr. Kim has provided. Thank you.
July 06, 2026
I loved that fact that she explained in detail why I needed to have the tests done.
June 26, 2026
Did well and everything. Thank you so much. Thank you. Bye.
June 22, 2026
everyone was extremely nice and made the best of the experience. the girl who inserted my iv did the best ever I've ever had. I am extremely difficult to find and poke and poke and pinch and pinch. she had me take a deep breath on count of 3 and inserted it at once, i didn't feel anything. The 2nd nurse demeaner was also exceptional. my nurse moving forward was kind and thorough. Although he didn't notify my husband I was delayed leaving , the doctor had started a new procedure and i had to wait. he was originally advised of 10 minute wait. it took 30 min for me to be dismissed. We missed not having to pay for parking by one minute. a 2nd phone call to him would have allowed him to leave and return

She was good and I enjoyed most of the conversation. Some of the things that I wanted I forgot about and didn't get back to her with them and I wanted to go over them with her. But I'm left to the next meeting. I'd like one quicker but I'll wait and see what happens. Thank you.
June 16, 2026
DR. Kim was very pleasant and knowledgeable. This was my 1st time with her, and she made me feel more relaxed about my upcoming procedure. The office staff was excellent as well.
June 12, 2026
I sat there in the office and waited 30 plus minutes for the doctor to come in which I think was a little bit ridiculous and no apology whatsoever. I know she's a good doctor and everything but my time is just as valuable as her time too. So I don't appreciate it when I have to wait that long in the office for a doctor because I never have with any of them. Actually PIH is pretty good with all their doctors this is the only one that I have to complain about waiting very long to see her.
June 11, 2026
Unfortunately for other medical offices, Dr. Katherine Kim and her staff were professional, knowledgeable, courteous, efficient and caring. That's got to be hard on those other, subpar offices. I scored though so I'm happy and that's all that matters.
June 09, 2026
My name is (PHI removed), and I want to tell you that everything went very well at my appointment with the bowel specialist. She was very kind and listened to everything I had to say, taking notes on everything. The nurse who saw me beforehand and everyone in the office were also very kind. They helped me whenever they saw I needed it, and I'm very happy with.
May 29, 2026
My Son has a problem that no was able to completely solve. What she said to do makes since. I will follow her instructions and come back for an appointment in 6 months.
May 29, 2026
Dr. Kim treated me with the upmost respect. She listened to my concerns, and came up with a plan of action. She is a true professional.
May 20, 2026
Yes, I think it would be good if the provider after your procedure called you to see how you were doing.
May 20, 2026
Dr. Kim was very thorough. We discussed current issue and past results that needed to be clarified. She gave me good advice in moving forward.
May 18, 2026
Dr. Katherine Kim was very professional and efficient. She attended to me immediately, and her assistant speaks Spanish and gave me the correct instructions for my upcoming colonoscopy. I'm very happy. Thank you.

February 27, 2026
Yes, I'm very impressed with Ms. Katherine Kim, doctor. She's very willing to look into the situation to see if there's something else that could be done to help, and I appreciate that very much. And she goes another step forward to see if there's something else that medication that she can give me that would be better for me. I appreciate everything that she does. Thank you.

Hello, Dr. Kim was very respectful, very nice, very knowledgeable. She listened to my concerns. She answered my questions. She was very caring and I appreciate her professionalism. Thank you.
January 26, 2026
I appreciate Dr. Kim actually giving me an answer when I asked what should I change in my diet and she actually gave me some examples. I really appreciate that feedback. I don't get that from many doctors.
January 19, 2026
I would have liked a little more communication with the doctor. I felt that she was really giving me medication rather really than wondering how my total health was. I would have liked a little more physiological information about what was happening to my body. Thank you.
January 16, 2026
Dr. Kim was very kind and informational. She was very clear on how colonoscopies were done. I have put off anywhere from 20 to 25 years for having a colonoscopy. With her explanation I changed my mind and I am going to have it. I told her a problems in the past and she assured me she could take care of that. I feel she has an outstanding bedside manner.
January 15, 2026
The receptionist was extremely helpful and very efficient and Dr. Kim was very nice and very smart.
January 12, 2026
She explained everything completely and I understand.
January 05, 2026
I accidentally pressed one, which means no, refer to family, and yes, in fact, I referred the doctor to my daughter who needs a new GI doctor. My son-in-law also will be going there. So I just wanted to let you know that, yes, I would be referring her. She was excellent, very informative, and she really listened to what I had to say about past experiences that might be causing the problem I'm having right now. I want to thank you. Later. Bye.

December 19, 2025
The staff was very friendly and helpful. The Dr. was patient and easy to talk to.
December 18, 2025
Yeah, my prescription was never called into the pharmacy. I was just kind of, I meant to call, but I got carried away with something. But anyway, that's my big deal.
December 16, 2025
The service was excellent.
December 16, 2025
The doctor and the doctor's office were excellent. It's not so fun to pay for parking. It seems like the hospital ought to be able to cover that.
December 09, 2025
It was a great experience and I felt very comfortable with this provider.

Dr Kim spent enough time with me to explain things and listened to my concerns. I appreciated that.
November 11, 2025
My experience with Dr. Kim was great. She's new to the office there and I was happy to know that I will be following with her as a new patient also. I pressed the wrong keys for the first three or four questions. I put a one when I should have put a four. So if you can go back and trace that and correct it for me, I would appreciate it. Thank you very much for the call.

Very smart and Intelligent Dr. KIM
October 28, 2025
Hi, well, everything seemed to be okay. The staff in front of the desk was Katherine Kim. I didn't pronounce the word right, and she kept repeating me, and I'm not very good because I'm going through a lot of stress with all this that's happening, and medication I'm taking, and the surgeries I went through, and she explained to me, but sometimes I have a hard time to comprehend, so I don't pronounce the words right, but she didn't need to repeat me over. It made me feel uncomfortable. That's the only thing I appreciate that she would not do to people that don't know what's going on in their life and the stress they're going through, especially at my age, at 66, and all these surgeries that I went through. That's all. Otherwise, she seems like a nice doctor, but if she would just not repeat me, I'm sorry, I don't speak very well, but I would appreciate if she would have a little bit more patience with that and start repeating the way the word was. Thank you so much.
October 28, 2025
We're very happy that Dr. Kim was able to see us quickly and efficiently was able to answer our questions. Thank you.
October 20, 2025
She was patient and informative. Very pleasant experience.
