Dionisio Dabu MD is a board certified Family Medicine physician that enjoys his career and the opportunity to help his patients. Born and raised in the Philippines, as an asthmatic Dr. Dabu spent a large part of his childhood indoors or at the doctor's office, since there were no inhalers or medications available to treat his asthma. 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. Dr. Dabu encourages his patients to live a healthy lifestyle, watch their diet, and exercise. Dr. Dabu enjoys spending his free time with his wife and children.

Very helpful staff and doctor, thank you.
September 08, 2022
Dr Dabu did not take his time listening to my concerns. He made me feel like I was wasting his time. While listening to my lungs, which I was in there for a lung infection, he barely tapped the tethescope to my chest a couple times. This wasn't the first time feeling this way under his care either. I will be looking for another provider.
September 08, 2022
I was charged a $25 office co-payment to establish care with my provider, but that doesn't mean anything. It just means to go say hi to your doctor when you first see him. Which I think is ridiculous. So, I paid $25 to say hello to the doctor that I was going to go see anyway. I've never had that... this before, except for this doctor. I don't know what happens.
September 06, 2022
Nothing, the service was very good.
September 01, 2022
My appointment did not go as expected. The Dr. rushed through the process- didn't care to know how my incident happened and why I was there . Also took notes on a sticky pad - seemed unprepared. Definitely not what I expected as I had never had such a negative experience with any other medical provider. I was completely caught off guard by the lack of professionalism and empathy.
August 25, 2022
Everyone was very nice and professional.
August 24, 2022
The doctor attributed my health problems to the fact that I am depressed and fat and I did not want to do blood tests, I had to ask him several times to do tests to see what I have and with a bad attitude he placed 1 order because I asked him saying that what I have it's depression and I'm fat. I didn't think the way he treated me was respectful.
August 23, 2022
Pointless appointment did not feel like it helped in anyway
August 22, 2022
Overall my visit was a good experience.
August 17, 2022
There are some people in this office that do an excellent job, and then there are some people who are rude and not very helpful at all. So, I just want to say that for the people that go the extra mile, I appreciate you. And for those that don't, they should find a different kind of job or get retrained. Thank you.
August 15, 2022
Dr. Dabu, has been an excellent doctor. I've had him at least15 to 20 years. And I never had any problem with him. And every time I had a concern, he handle it in a timely manner. I'm really satisfied with him.
August 11, 2022
I went in for a physical and was expecting them to do a urinalysis at the lab and draw two or three tubes of blood, but to my surprise it was only half a tube and that was it. At first I was worried because they didn't do a urine test, but I called and was told I didn't need it. I don't quite understand it, but it seems that's how this doctor works.
August 09, 2022
(INAUDIBLE) bed, side manner. And that is what I like. And the doctor, thank you so much.
August 04, 2022
I was able to get my prescriptions filled , but not able to get more info. I was not able to under stand him, possibly due to mask a nd my hearing loss. I will not request him again .
August 01, 2022
Thank you for taking good care of me. I like your work and I already have the reception and the

You can most improve by giving appointments in a timely manner. My experience was...we had to wait over a month to get an appointment.
July 15, 2022
Excellent doctor
July 11, 2022
Dr Dabu is the BEST !
June 17, 2022
Staff was incredibly helpful and kind. Dr. Dabu is friendly and direct. I'm very impressed with the efficiency of the office work flow.
June 14, 2022
Dr. Dabu should have prescribed medication to me because I was feeling sick, but he denied it.
June 07, 2022
I had very poor service. I was unable to visit with anybody. Also, when I spoke to anybody, they were unable to give me anything that I needed to know, in regards to my health care. I am very dissatisfied, and I will not recommend this location or any PIH locations to anyone I know, ever.
June 02, 2022
Dr. Dabu has been my Primary Care Physician for several years. I trust him wholeheartedly.
May 31, 2022
It's been the worst in my life! Broken wrist for a week and have not been taken care of. Ridiculous!
May 25, 2022
Very professional to my needs
May 24, 2022
I am very grateful for pih. I used to have kaiser. Then company changed carrier and I had been assigned to office that was subpar. Felt like third world office. Finally found pih and is comparable to Kaiser. So A plus!!!!
May 20, 2022
I would of like for the Doctor to had talked to me and asked me my concerns before he did my paps. It was kind of uncontrouble and he seemed to be in a rush.
May 19, 2022
Good afternoon, (unreadable), I don't want him anymore because he didn't treat me, like the prescription that according to (unreadable) it didn't arrive at Walmart, I went to pick it up according to the prescription yesterday and they didn't have it when supposedly they were to have it on Thursday and (unreadable), sorry for the inconvenience, okay.
May 19, 2022
For this being the first time, it was very good. The doctor is very kind and he allowed me to express my health concerns.
May 03, 2022
I liked how they treated me, thank you very much, of course I would recommend it, okay,
May 02, 2022
I thought the doctor was really good and I just want to check out another doctor, because the doctor that I choose, I hope will be the doctor until I leave this Earth. I'll be 70 in September, so I want to make sure I make the right decision. So I will know by the end of the month, which doctor I'm going to take. God bless you. Bye. Bye.
April 27, 2022
Hi, I'm considering changing. Providers and location. My original doctor is (name removed), and I've been very satisfied with the service. I feel that a lot of doctors, don't really care so much for their patience. And that's the treatment. I feel at this location with (name removed). And with this doctor that, I just saw it just seems like, you're well, just one more person to see. But really, it's not the carry isn't really there. It's just It just seems like you're just Another Piece (word removed) and because of that, I'm currently looking for another provider. I've been with you guys for a long time, but I feel very disappointed.
April 18, 2022
Dr. D. Dabu is the best Primary Doctor in my book. 1000 percent guaranteed.
April 08, 2022
I was treated with great respect and kindness by the doctor's assistant and the doctor I am very satisfied with my visit.
April 07, 2022
DR. Dabu and His Nurse (name removed) have great bed side matter
April 07, 2022
I was having so many issues with my insurance and this facility was so nice to help me with this and was seen by a doctor and fitting the help I need. The staff is very understanding a patient with helping me
April 06, 2022
To the attention of this doctor he asked us questions that I do not answer questions, that what daughter wanted the questions that have been for me, I do not answer any more questions, questions, anything that it would be better to go to your family doctor, who can you believe, we agree with that agree with that.
March 16, 2022
Oh, well, that (PHI removed) and for me is excellent, very clean, tidy. I love all your services that I would recommend and I had insurance before and I was with them and I came back because I love all the services and everything, thank you.
March 16, 2022
(unreadable) the doctor who treated me. For me he was a very good person, very understandable and very sincere, thank you.
March 16, 2022
I had to wait 40 minutes to get my TV shot check. So seeing patient timely would be something you need to improve on. Thank you.
March 11, 2022
Dr. Dabu was very respectful and professional. I felt comfortable and safe. As always, the staff at PIH are friendly and welcoming. Thank you.
March 09, 2022
waited for the doctor a long time in the exam room
March 02, 2022
I came in for a follow up after having visited the ER for having an allergic reaction where my face was swollen and my scalp and back were itchy. The doctor tried telling me it was probably my mascara, which I've worn most my life. It felt like he wanted to send me on my way after that, and I have to request to be referred to an allergy specialist. I also told him that the doctor in the ER mentioned my right ear was really dirty, and asked him if they could do an ear flush to clean in out. He told me to go to CVS and buy an ear cleaning product called Debrox. And he didn't even bother taking a look at the ear. I pay my copay and pay for my insurance. So I do expect to have a better patient experience and not feel like the doctor wants me in and out.
March 01, 2022
The Dr. was supposed to call me after evaluation of my x-rays. It's been 12 days, and yet a follow up call. Now I find myself seeking g another provider, and start the process again.
March 01, 2022
Well, I went to take a physician and they make a schedule for me around 2:30, but they never told me, come with an empty stomach. So, I went there and the doctor say, you know, it's not going to work because you have food in your stomach. So, next day I come back, 8:00 in the morning. I was about to leave and the nurse forgot to give me the test for the cancer, colon cancer. So, if I don't ask give me the (INAUDIBLE), she would never give it to me, you know. (INAUDIBLE) I came the other day, never told me to come with my stomach empty and now I'm about to leave and you forgot your test for the colon cancer. If you like, you know, I don't think it's cool. Okay, (INAUDIBLE) (INAUDIBLE) whatever.

As a patient I would appreciate it if appointment or available when needed. Because many times we're waiting to be seen.
November 10, 2021
First time here and I was thankful for the quick appointment. It was clear when I spoke I was heard and I appreciated the doctor's calm approach to speaking and their explanations. I felt comfortable with a usually stressful situation. The ability to have a remote appointment was appreciated. Also the staff was quick and professional in scheduling.

October 22, 2021
Dr. Dabu is nice and east to talk to.
October 04, 2021
Okay, so Dr. Dabu used to be my doctor before he left the Long Beach facility when it was Pioneer than PIH and he went to Downey. So I went with [name removed]. So I didn't have to drive Downey and [name removed] is a very good doctor, but in order to see her it there's always always a wait, you're always there an hour and a half. And so I went back to [name removed]. I tried to get in a week ago, with [name removed]. And they came to me, my appointment was at 3:40. I got there at 3:30, and they came to me at 4:15 and said, she's an hour and a half behind. So, I got frustrated. And I said, can you make me appoint with [name removed]. So I'm going back to [name removed] even Downey. I live in Lakewood. And that's really the main reason, not because I don't like [name removed]. It's because it takes way too long to see her. Personally, I think it's two reasons 1, you over booked her.
