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.

I did a low rate to the Dr's office stuff, because it was a phone appt. So I never saw or heard the stuff members & I did that rate because there's no other available close to the answer. Thank you

I was supposed to go to the office on 11/29, Friday but since my visit does not require any physical examination, glad that the office assistant offered virtual/phone consultation instead. It is very much appreciated. Please extend my appreciation to Dr. Dabu and the person who assisted me.

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.

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.
