So I just want to give them kudos and thank them for everything they need from you that day. They were excellent nurses. Thank you. God bless.

March 25, 2022
The Dr and whole staff were very respectful and friendly.
March 24, 2022
I liked Dr. Ashwin very much, had no problem with him at all. The only thing that I was very upset about was the nurse could not find a vein to insert IV. She tried several times and it hurt. I finally told her to stop and get someone that could find a vein. She came back with a nurse named (name removed); it took two seconds for her to insert the IV. I wished you could see my hand and arm, total black and blue the next day! Maybe the nurses should get help right away if they can't do something.
March 22, 2022
Always professional and a respectful experience.
March 21, 2022

March 11, 2022
I asked not to have anesthesia as I did not have the previous 2 times before. He had a consultation with me prior to make sure I could handle the procedure while awake.
March 09, 2022
After having (name removed) for many years, I was not sure if I had made the right choice to see him. I was very comfortable with him. I feel it will work out okay for me. I was sorry to lose (name removed) but every thing change these days. At 85 yrs. I will be okay for whatever time I have left.
March 04, 2022
(name removed) is most remarkable, she caught me twice and then shared some info...............she said slow down! afte all the stuff PIH staff has had to deal with past 2 years and SHE still provides care.

The staff was very calming and helpful. A particular staff person, [name removed], was the key for me. Due to unique conditions I have, I have been required to have endoscopic procedures for more than 40 years. Carol is so reassuring and knowledgeable that I remained calm and comfortable during the entire prep time.
January 28, 2022
Great people.
January 24, 2022
We'll see if this prescription helps. I've been down this path before. Doctor is not very reassuring.

At all stages of the prep, staff members were gracious and professional, treating me with courtesy and dignity.

Doctor was extremely professional, accurate answered, all my questions to the up most. The family of the actual staff was great. Gave me all the information. I needed. Top Notch, I approved. Thank you.
January 14, 2022
I can't say enough good things about the doctor, Dr. Ashok and his crew, and his staff, the nurses were wonderful. Everybody was very polite, helpful, listened, understanding. I just want to make sure that that last question was answered with a positive response. It was supposed to be excellent. Wasn't supposed to be, I was putting in a ten and I think it took it as a one, which would not be what I would put in there. Okay. So if you got any more questions, feel free to give me a call, and I really did have a good experience with them, but I would recommend the PAHN, and my doctor. Thanks. Bye.
January 14, 2022
My appointment was not scheduled even though I had an email confirmation. Thankfully after I showed them the email, they were able to get me in for my procedure.

He's a very good doctor. Always patient
December 15, 2021
The doctor was great, and I...he sees my mother and she trust him and his happy with him. The only issue I am concerned about...and this is her daughter, and I'm approved to speak on her behalf and make appointments in her care, but the timing, it takes too long to be able to see the doctor. We had to wait quite some time, so...but he's very good. It's just, maybe he's too busy. I don't know. Okay, Bye Bye...But he did take plenty of time with us.
December 13, 2021

Excellent experience overall from the doctor and front staff. To the girl that gives the appointments and asks one to stand on the side. They're a courteous way of asking. I almost walked out.

November 29, 2021
Excellent provider extremely satisfied with his care.
November 23, 2021
You can mostly approved by getting rid of your damn pay for parking that you have it seems to be a source of frustration for everybody that goes to the Wells Building to Dr. Ashok building or to the hospital. If your system doesn't work, the money doesn't matter, it's just it's a pain in the rear end and everybody wishes you and get rid of it. I don't know how many people have to complain before you listen. Thank you. Goodbye.
November 22, 2021

Presbyterian Hospital is an outstanding Hospital. Every professional person that we have dealt with there has been extremely, extremely competent, good, understanding and everything. I would never ever want to go to any other hospital, but Presbyterian our whole family goes there and we really feel that we are taking care of in the greatest and best manner. Thank you.
November 16, 2021
You m might want to teach the office staff not to let their phone ring anywhere from a minimum of 30 minutes to over an hour before a patient gets to speak to an operator

From admittance to discharge, each staff member treated me with dignity and respect. I was very concerned and nervous about the procedure, however, each staff member was there to help me through it and i thank each member. Im sorry but I cannot remember each RN but thank you to [name removed] and every staff member thereafter.
November 09, 2021
Great experience, the staff is very friendly and the doctor cares, listen and answer my questions in a way that I can understand them.

I hear very poorly, the staff was very helpful in their communication with me
November 08, 2021
The parking fee is a slap in the face. Patient are already paying often healthy fees to be seen and to be treated by physicians at PIH. Then the fee just to get out of the parking lot is a cruel slap.
November 01, 2021
Excellent experience. At first I thought the front office was rude as I was not greeted but it turns out both front office clerks were on the phone at the same time. Overall wonderful experience.
November 01, 2021

October 13, 2021
Dr Ashok very friendly
October 07, 2021
The doctor's staff is useless. I would like them to change everything because I do not understand what the doctor says. He took good care of me, but the staff who work with him are useless. OK. If I said that to meet you in this consultation. Ah, like you when I say they are useless, they are not understood, they do not know what they are doing. The staff the doctor I have a lot of time to treat him and yes he treats me well, but it seems that the staff changed him or I do not know that it is useless, that is all I can say goodbye.
October 07, 2021
Dr. Ashok and his Staff were wonderful.
October 05, 2021
The office staff at the check out desk needs to make things more clear.
