Experience with hospital, staff and Dr Kim went very well.

Only Anesthesia did not introduce himself immediately but once I asked for the anesthesia he presented himself quickly. Overall, I was treated with respect and my experience was as pleasant as a colonoscopy could be.

All of the care givers were great! However my procedure occurred 2 hours later than scheduled. Instead of 1 PM I didn't have the procedure until 3 PM.

First time meeting Dr. Kim He explained to me very well, you know what was going on, and you're very nice person. I would definitely see him again. I want to say one of my first impression of him. One of the top 3 best doctors I seen in a long time, so, you know, I trust him. So I'm going to go for with his recommendation then and I'm looking forward to seeing him again. Thank you.

September 22, 2021
Very pleasant to talk too.
September 22, 2021
My visit with Dr Kim was the first time I felt hopeful about having some relief for my illness. Most times I am told we don't know what's wrong in a variety of different ways. This time he knew what I was talking about and he offered solutions immediately. It was such a relief to have some answers and insight into my symptoms. He is a truly kind man. Exactly what you look for in a doctor.

The office was very pleasant, clean and professional
July 06, 2021
When I arrived the staff was pushy about a face covering so I started to comply and they insisted I could not wear my own and had to wear their mask. They charged me a $10 copay yet Dr. Kim wondered why I was there. We sat there and had a pleasant conversation and he was helpful assisting me with choosing a new family doctor. He wants to see me again in 4 years.

I'm grateful and honor that Dr Kim was able to assist me. I know now the difference between Dr and Specialist. He was very professional and knowledgeable. He explained everything clearly and with examples easy for me to understand and follow up. Dr kim is a great asset to community.

We appreciate that the office was able to accommodate an earlier appointment due to the pain my mother is experiencing.
April 21, 2021
I've been with Dr. Kim over 20 years. Due to a family history I get an colonoscopy every 5 years. In the past, prior to him joining PIH, I just needed to call and schedule, this time, PIH said I must see the doctor prior to scheduling. So, it cost me my co-pay just to schedule a colonoscopy. But, it was nice talking with Dr Kim and getting caught up.
April 21, 2021
Very good doctor, I felt very comfortable, he is very professional. And your staff too.
April 21, 2021
Just wanted to let you know I trust Dr. Kim to the extent that I am willing to travel nearly 60 miles, just to have him do my examination.
April 20, 2021
Hi. I know Dr. Kim almost 30 years and he save my life couple times. He's one of the best doctor I ever see. And I really appreciate. God bless him and I hope he can be a doctor at least for 20 more years. Thank you.
