Thank you.
October 29, 2024
I had a wonderful experience. Everybody was so attentive, very nice. They took the time to answer my questions. I would definitely recommend the office and all of the employees who helped me out that day to any family and friends, if ever they ask. Thank you. They also made me feel very comfortable with the procedure.
October 29, 2024
I appreciate the professionalism.
October 25, 2024
I would like to say thank you to the Hospital staff and Doctors everyone was kind, caring and very nice.
October 24, 2024
A very professional doctor, I felt comfortable talking to him, I would definitely go back, but PIH Downey does not have the specialty for my esophageal surgery, so they sent me to a doctor from PIH Whittier who was handling my case.
October 23, 2024
The wait time was awful. I had my blood pressure taken, then waited about 20 minutes to talk to the resident doctor and explain my symptoms to him. Then I waited another 20 minutes to talk to the doctor and tell him the same thing. I spent about an hour there, and all I got out of it was a referral to another specialist.
October 22, 2024
I felt very confident. Everyone treated me with respect. Thank you.
October 22, 2024
The staff was very efficient and courteous, they spoke to me, not at me. They asked me questions, they did not go through the motions of their job. The experience was personal not routine. I would %100 percent recommend the staff at PIH Downey for your health care needs.
October 15, 2024
Excellent service, good quality, attentive people. And well, I am very happy with the procedure I had and I thank you for everything.

September 24, 2024
All round very good experience. Staff were friendly and businesslike. They explained the procedures processes and estimated times. Thanks for your service.
August 23, 2024
It was a fantastic experience from the moment I checked in, to the procedure prep, to the procedure itself, to the recovery, including being wheeled out to my ride in a wheelchair. Dr. Nguyen's team is caring and friendly and efficient and organized.
August 22, 2024

Friendly, sincerely, Pro and knowledgeable.
August 02, 2024
I was nervous going into this preventative colonoscopy procedure. I hated doing the bowel preparation because the Suprep tasted horrible. I'm lucky I didn't vomit. I was treated wonderfully by the entire staff. I appreciate being addressed as "Mr." The staff always explained what was happening and what to anticipate, each helped ease my nervousness. The staff always answered my questions. I really appreciate the minute I had with the doctor at the end of my visit. It was additional confirmation to what the rest of the staff was telling me. I'm very grateful to the staff for their wonderful care. I highly recommend this team!
August 01, 2024
Good evening. I think that Dr. Nguyen was a good doctor. However, I think that there is just too much, too many patients that are being referred to both of them at this office, at the Digestive Health Office. And I think that maybe it needs to be expanded to include another doctor or two, another specialist in that field, just because it's really difficult to get an appointment in a timely manner and you have to wait months out and call daily to see if there are any cancellations. So it's just very difficult as a patient to feel comfortable with the timeframe, especially when you're not feeling well and you have to wait three months because the doctor doesn't have any.
August 01, 2024
I like Dr. Nguyen.. he was a new doctor for me and I felt very comfortable with him! I am excited to have a new gastroenterologist! Thank you PIH for providing yet another wonderful doctor!
July 30, 2024

DR. WAS VERY NICE AS WELL!
July 23, 2024
Very good
July 23, 2024
Everyone was very professional, knowledgeable, and helpful. The only thing missing was a map of the hospital to be able to locate the registration office. I am glad my sister and I were early, because we were going around and lost until someone that was passing by asked if we needed something and took us to the registration office.As soon as I arrived to the hospital, I asked the person that sits at the information desk and I was given directions that the second hallway to the left. There were several hallways, Anyway, I appreciated the nurse that help us find the registration office. I was at the same hospital for surgery a couple of years ago and things have changed, that is why I asked for directions. I would suggest for the person making the appointment and scheduling the procedure to mail a hospital map. I am sure I was not the only one getting lost there.
July 22, 2024
Very good service

I want to tell you that you did not do your job, very badly and I want to say no.
June 04, 2024
1st time having colonoscopy done and needless to say I was very nervous. Nurses, anesthesiologist, and doctor were kind and explained everything so I knew what to expect which lessened by fears. They were wonderful!
June 04, 2024
It was an excellent experience and the nurses were very attentive with me since I was very nervous and I get anxiety . Really nice staff!

April 26, 2024
It was remarkable. Always have been. The team including the physicians are out of sight. They are kind, compassionate, and profession. So far they out various facilities. Keep up the excellent work PIH.
April 24, 2024
My doctor sent me to that doctor of yours to have a colonoscopy. He sent the order but Dr. (name removed) says in her opinion I don't need it. My doctor didn't listen and I was waiting a month for this appointment, and just so he could tell me (unreadable). I didn't like it because now I have to wait more time to see if there is another (unreadable). So then, I didn't like.
April 24, 2024
Yes, our recent visit with Dr. Nguyen was very informative. He was very good. I trust him. Oh yeah, I trust him.
April 22, 2024
I explained to the nurse in so much detail what my complaint was and when the doctor came in he basically disregarded everything that I stated to the nurse and chalked up my problem to me being overweight, my BMI is too high. He suggested everything that I've already told the nurse I am doing and he was in and out of the room within minutes. I feel like he completely disregarded everything that I said and he did not take me seriously because he took a look at me and saw that I was overweight so he assumes that I'm just eating everything under the sun and not controlling my diet which I am. He felt that I was not exercising which I am.
April 18, 2024
Too long to made an appointment
April 09, 2024
Everyone is very kind, thank you, they serve you very well, nurses, doctors and everyone is very kind, they all serve you very well, they work excellently, everything is very clean and well taken care of, thank you.
April 09, 2024
Extremely impressed in every way. Could not have been happier with the entire experience. Incredibly nice, attentive staff! Thank you for making an unpleasant surgery so easy.
April 04, 2024
Yeah, everything was overall excellent. The only feedback I have is when originally my doctor called the specialist for this department and kindly requested to see me earlier and they say, yep, they made some accommodation and that they were going to call me to set up that appointment, but it never happened. So I just kept my original appointment. So there was just a miscommunication around making sure I did get an earlier appointment. So that's the only feedback I have. But other than that, everything was great.
April 02, 2024
I am very satisfied with the attention and service of all the employees at that place and I would recommend it to 100 places. My name is (PHI removed), thank you for the good service you provide, happy afternoon.
March 28, 2024
Dr. Nguyen is informative, efficient, and caring! It's very evident that he's concerned for your well being. He takes the time to explain results and questions and puts them in layperson's terms. No confusion!! Don't lose him, PIH!!!
March 27, 2024
Excellent service provided, made me feel extremely comfortable. Staff very friendly. And professional.
March 25, 2024

March 25, 2024
Yes, the staff was very nice. The doctor explained everything to me in detail. Thank you.
March 19, 2024
No, all the nurses were very friendly and I would gain experience because they treated me well and everyone was very attentive and even the doctor, I would recommend anyone there with that hospital. They were excellent, thank you.
March 15, 2024
I had a great experience from beginning to finish. There's no room for improvement. I just want to say thank you for all the help they provided. Thank you.
March 14, 2024
Great experience, hope procedure goes as well
March 14, 2024
Doctor, did not take the time to listen to me or take the time see all medications I take for my condition which are not helping me. He didn't prescribed another medication to the serious stomage/ colon problem I have for over 3 months. I felt no real help. Very unsatisfied with this consultation!
March 13, 2024
very good
March 11, 2024
Dr. Nguyen presents himself as a friendly person, he makes eye contact, he listens to what I have to say, and is friendly. This is not a common trait among most doctors. I feel comfortable sharing my symptoms without feeling bad about myself.
March 11, 2024
Excellent doctor and staff.
March 05, 2024
I didn't need to schedule an appointment.
February 27, 2024
I liked the hospital and they were very kind and they treated us very well and I am satisfied (unreadable).
February 27, 2024
I always recommend this hospital to people. All the staff are always very friendly and they serve you quickly.
February 26, 2024
Well, the care they gave me ... I went in early and I'm always organized and I was there at the time they told me to take my daughter in. The only thing is they didn't explain well what I wanted to hear in regards to the vaccine they were administering. That's why I told them I didn't want the COVID one, but I was told it wasn't that, that it was to prevent getting a fever or something like that. So then, I had to figure out through other ways what it was for. Okay, thanks.
February 26, 2024
Excellent service.
February 23, 2024
The team that took care of me from start to finish were amazing and treated me with so much care. what a great team! I'm so grateful for all of you. (PHI removed)
February 20, 2024
They did everything excellent. Thank you for your good attention. Have a good night, goodbye.
February 16, 2024
My overall experience was very good except for the fact that when I woke up I realized my tongue was hurting. I asked one of the nurses, did I bite my tongue? And I showed it to her. She said possibly it's red but it's not bleeding. To this day, four days later, five days later, my tongue is still hurting. So I don't know what they could have done to prevent that, but I don't think that should have happened. Thank you. Bye.
February 13, 2024
Everyone was extremely nice and helpful. Very good experience
February 08, 2024
On the last question I messed up. I pushed one thinking I'm going to push a ten for the yes I would definitely recommend. I actually pushed one and it went to no I wouldn't recommend so that's not right. That's not correct so I'm just letting you know I meant to push two. Okay thank you. It was great. He's a great doctor, got a good vibe from him. Alright, thanks.
February 01, 2024
Although I don't speak Spanish, I trusted your interpreter with what I was talking about and what I needed to know.
January 23, 2024
Everybody at the hospital from check-in to exit was extremely well-mannered. Well, they're excellent throughout everything.
January 18, 2024
He didn't pay much interest to what I told him about my pain.
January 11, 2024
Everything is very good.
January 10, 2024
My PCP told me exactly what Dr. Nguyen said. He didn't have any suggestions for improvement, so what was the point of using my time and paying more for a specialist? I was disappointed with his care.
January 05, 2024
I had a colonoscopy at PIH hospital in Downey. The entire staff was great. Everything was on time. From top to bottom, all were very thorough and informative about how the procedure was going to take place. They all took the time to explain and make me feel in great care. Thanks to all staff.
January 03, 2024
They assisted me very professionally and answered all my questions.
December 29, 2023
Hello, the only thing I find very bad is that the doctor does not send me anything after follow-up. I had many questions, but no, I am not able to answer. I asked the nursing people the people who took the ones they gave you to prepare me before the procedure and those people who are very kind answered my questions, but the doctor did not when I knew the doctor told me that finishing the procedure from anesthesia. He was going to be there to explain to me what had happened to explain the photographs he was going to give me, but he didn't show up. There was another person who couldn't tell me that because she wasn't the doctor and I didn't see him anymore, I was still left with a lot of doubts.
December 29, 2023
The one from (unreadable) cannot attend the appointment, thank you.
December 22, 2023
Loved all the staff, it was good to me. All the doctors and everything was good. Blessings.
December 14, 2023
Dr. Andrew was very kind and very sociable, very nice and explained everything clearly. And he paid attention to what I have to say. Congratulations to all of you. Thank you.
December 12, 2023
The doctor was 45 minutes late to the appointment and nobody in the facility spoke Spanish. They had to bring some robot or find an assistant to explain everything. They were not professional and I had to explain things to each an every one of them surrounding my medical condition and I did not like it. I wanted to switch doctors and I will be finding a different primary physician. Thank you.
December 11, 2023
The doctor and office staff were very helpful, courteous and understanding. Thank you ?
December 06, 2023
I'm a new patient and a bit apprehensive. But Dr Nguyen put me at ease.
December 05, 2023
Hi, I was definitely a complicated case and the doctor was more than patient, more than happy to help and even came in on a time where he wasn't doing hospital stuff just to care for my needs. So it was amazing to have him as my doctor. Thank you.
