During those early years, Dr. Dabu developed strong relationships with his doctors and grew to admire them and their work. Although his father wanted his son to pursue a law degree, Dr. Dabu knew that medicine was where his heart was. He eventually came to the U.S. with the persuasion of his family.

I spent over an hour in the exam room just to spend 5 minutes with the doctor. The doctor seemed unsure of what to do. I told him I had an ear infection, he gave me medicine for that but didn't say anting about my sinus congestion or infection and headaches. I was shocked to only revive medicine for the ear infection at the pharmacy. They also stated my prescription was sent to the pharmacy already but when I got there... the pharmacy hadn't received it. When people are sick, they are uncomfortable. There's a lack of empathy when your appointment is at 9:40am and you don't leave till 11:30am. You shouldn't do that to people.

It was my first time visiting PIH. Everybody was very helpful. But I just wanted to have my results or my diagnose. What was wrong with me like in a paper. So that could improve. And then also like a follow up. That's all.

Dr Dabu and staff were professional and understanding to my health concerns. Asked appropriate questions to determine any further needs.

This was my first time at this provider. I quickly had to choose a doctor due to the pain I was in. I was seen by a nurse and the doctor. During my visit with my nurse where she took my vitals and asked me why I was there, she didn't speak to me at all. She didn't tell me my blood pressure, or ask the simple question of how was I. The doctor was similar. I felt rushed in and out. I told the doctor and nurse that I had a baby a few weeks ago, and neither of them acknowledged that fact. I repeated myself as I wasn't sure my treatment would affect my breast feeding. Though, I didn't feel too rushed as my appointment was double booked and I heard the receptionist tell another patient. I will not be returning. The entry way also felt dirty as well as the lobby.

All negative was for the Dr. Dabu, not for the staff, not for the nurses, not for receptionist said, the timely appointment, I did get an appointment timely. Unfortunately, that doctor did not listen to me. Does not help me out for anything.

Really need to improve appointment availability with PCP selected. There hasn't been a single time I've able to schedule an appointment with PCP on my plan. All available appointment dates are months away. This single reason would make me consider a different health insurance company.

The staff is very professional and friendly.

He was extremely persistent. I couldn't seem to log on to the account. And he went ahead and called me which was fantastic. And we handled the appointment over the phone. So it worked out very well. He was wonderful. Thank you.

Dr. Dabu is great, I've been a patient of his for many years now. He answers all my questions and I'm never made to feel rush. The new facility is also nice and clean and much more spacious.

Great provider very professional and understanding
March 11, 2021
I was hoping to get my mammogram results since it has been three weeks and I have not received my results. The doctor had the results of the breast ultrasound , which was done on the same day as the mammogram, but could not find the results for the mammogram.
March 04, 2021
Doctor was not attentive to my medical need and didn't give me anytime to explain about my internal bleeding. He shut me down and send me away. I was given a list of lab to call to get blood work. Compete list had non working numbers. Requested assistance to get me in with obgyn and was ignored with my needs. Still bleeding and visit was useless. Completely disappointed and will consider changing medical faculty. Horrible experience
February 24, 2021
Dr. Dabu is a wonderful doctor
February 17, 2021
He just doesn't seem interested in the actual patient. I understand he's busy but he doesn't take an interest or doesn't seem to care too much about any type of small talk Conversation.
February 12, 2021
He spent time listening to my problems did not rush me and gave me information about the medicine and explained to me my condition and why he was given me the me the medicine
January 25, 2021
Thank you Doctor Dabu.
January 18, 2021
The doctor that I saw on this last visit to PIH, had no sense of caring what I want or I was I in there for him. He didn't care much of my pain that I was feeling at the time. He had no interest in hearing what I was feeling, he just kept saying negative things in regards to what I was trying to explain to him. So I would never recommend anybody to go see him again it was my first time seeing him, and I would never go back with him again. Not a good doctor to have in your company, based on my experience with him. I'm sure he's done this in the past and it's a common thread that he does this to other patients, he thinks he has the right answers and it's what he said so, and I'm not okay with that.
January 15, 2021
This provider had no sympathy, had a rebuttal for everything I said, and did not explain things clearly. I left the office very frustrated.
January 13, 2021
I love that doctor, he's great, he's very respectful, very patient. In fact in my opinion he's the best doctor I've ever had. Thank you. I hope you keep him in your staff. I hope I can visit with him again because I really like the way he treats me. He's very kind. Thank you.
January 05, 2021
I just should taken a later appointment to see my own Dr with the knowledge of my own health history. Nothing against Dr. Dabu
January 04, 2021
Provider refuse to refill my medication given to me at urgent care and told me to go to the hospital, i had to go back to urgent care and they refill my prescription with no problem and also provided me with more medication. Very upset with his care and also changed doctors..
December 28, 2020
Great service always!
December 24, 2020
Never to use this doctor for a phone visit again it was useless and pointless
December 21, 2020
Dr. heard my concerns and advised me what I need to do i would recommend this provider
December 21, 2020
Has caring and concern with your well being.
December 15, 2020
Educate yourselves because some doctors clearly don't care enough to help you!
December 15, 2020
PIH is a good practice, but I will no longer be referring anyone to them and will be finding a new healthcare provider .
December 04, 2020
He doesn't care to listen to what I have to say or my concerns.
November 12, 2020
I LOVE PIH, I LOVE their Urgent Care doctor. However, there is some doctors and nurses there whom just rush through patients. Almost like a game of who can get the most patients in a day.
November 06, 2020
Health care has really taken a turn for the worst. I was looking for a GP and received minimal care. So as for me, I would go somewhere else until I find one who will look at me as a person and not as somebody who walked into a clinic with a complaint.
October 26, 2020
It was just a regular visit. Nothing new.
October 09, 2020
