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.

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.

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.

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.

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.
