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.

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

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.

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.

Fantastic job by Dr. Ashok and all of the staff at PIH Health.

September 02, 2021
Dr Ashok was timely and very thorough. The Dr was very professional and explained the next steps in the process so I could understand. Dr Ashok allowed me to pick the date of my procedure and the process prior to my procedure. And get this... He said If I needed this sooner he would double up to accommodate me. What Dr ever has said that to me, never!!! His customer service went above and beyond which made me feel comfortable for a uncomfortable procedure. The entire team there was great and I greatly appreciated that. Thank you Dr Ashok and your team!

Feel very confident with Dr. Ashok. Also, staff are extremely friendly and highly professional.
June 04, 2021
The whole PIH digestive health staff was great--from the welcoming and attending nurses (three of them), to the careful and thoughtful anesthesiologist (whose name I didn't catch), to Dr. Ashok, whom I'd also never met before. I'm rather a "special needs" patient in certain ways (such as needing the i.v. needle in my ankle instead of my arm), but instead of expressing one-size-fits-all irritation at my request, the entire team worked with me to make the experience seamless and almost pleasant.
June 03, 2021
Thanks for the timely and good attention.
June 01, 2021
Dr. Ashok is very professional and has excellent communicate skills. Very compassionate and is an exceptional Doctor. I am very pleased and appreciative how his staff interacts with patients. Respectful, courteous and pleasant.

All nurses are very nice
May 11, 2021
Everything was great but the front didn't let the nurse know that my husband was a gurney patient so was a little tight, the nurse said why didn't they tell me so that I can put you in a larger room. I would highly recommend this office.
May 11, 2021
After 2 years, several doctors, many tests, Dr. Ashok is the one who found my sons cancer. I have the deepest faith and trust in his diagnosis and treatment. He has been my doctor for several years. I would recommend him without question to family and friends
May 07, 2021
Shamefully, in today's day and age, customer service has been sacrificed for cutting back on payroll and pursuing productivity. Good and beyond customer service will always be key to the continued success of any business. Congrats on not forgetting the needs and comfort of your patrons/patients inquiries and needs. Team Ashok, I applaud you! Well done!!
May 06, 2021

Not the provider, but signs for parking are confusing. Considering there were people in front and behind me trying to back out of employee lot, signs need to be clearer.

Dr. and staff were friendly and efficient. I trusted the doctor to do my colonoscopy. I was able to choose the date and time that I wanted. The hospital experience was great.
March 22, 2021
The doctors visit went just fine. The only frustration was the paid parking machines and gates. I try and avoid coming to this location just because of it. It's a lousy way to squeeze an extra $3 from everyone who uses these facilities.
March 19, 2021
It was held in an upmost professional manner and made the experience very comforting
March 19, 2021
Staff were friendly and the environment created by them was excellent. A very positive atmosphere and very helpful.

27 days without a shower.
March 16, 2021
I was very impressed. I had this procedure done 3 times and this one with the doctor was the best and the most thing that I respect it and liked is he called and gave me the results himself. I'm very pleased with my experience with the doctor.
March 16, 2021

The medical secretary that provides Schedule she's not professionally trained. She didn't explained well and did not filled up the paperwork properly, confusing.

February 19, 2021
My experience was Amazing! All the Staff was extremely, caring.
February 17, 2021
Does not have a very welcoming attitude. Instead of a smile and how are you, it's more... what are you here for? When you need and want to know that you are a person instead of a chart... we didn't get it here.
February 16, 2021
Very nice doctor.
February 16, 2021
Just ok.

Our family likes Dr. Ashok. He seems very nice personal gives accurate information to us that we need he's kind and courteous and most importantly he speaks good English. And he doesn't Mumble and if you ask him to repeat something he doesn't give you an attitude.

The only stress involved with my visit is the parking.
January 05, 2021
