I was having extreme pain when I call the office. They were able to give me an appointment the following day, but the young lady I spoke to, who was very kind. She said, let me see if I can get you in today, and she spoke to Dr. Cao and they were able to get me an appointment that afternoon at 3:00. I appreciated it very much, and I want to praise both of them. The girl for getting me in and Dr. Cao for assisting me. Thank you.

David Cao was extremely extremely professional, listened to me and helped me understand what was going on and answered some very good questions that I had about my further treatment for my back. He is great, thank you very much.
August 03, 2021
David Cao is always very kind and understanding. Always listens to problems I am having. I object to paying to park to see my physician. No one sees you in 30 minutes. A sneaky way to fleece the patients. PIH should be ashamed of itself.
July 22, 2021
No, thank you. Dr. Cao was very sweet. Everything was fine. Every....the hospital's fine. That's why I go there all the time and so, thank you for calling. God bless.
July 08, 2021
The waiting times on the phone to make appointments are RIDICULOUS! For all providers!! I left three messages to make appointment because wait time was over 30 minutes NEVER GOT A CALL BACK!! Ended up waiting 46 minutes to talk to someone! And this is for all my providers. Thinking of switching to St. Jude if PIH can't get it together!!!!
July 02, 2021
The physician's assistant, for the most part, was very courteous and professional. However, he wouldn't even look at me as we discussed what was going on with me. Never turned and looked me in the face, as I spoke to them. Was looking at papers or looking at a computer the whole time. It would have been nice to have them at least look at me while I was speaking.
June 24, 2021
Great staff. Super professionals.

I've always feel comfortabl with the care I receive. Thank you
April 21, 2021
He asked me my pain level I told him it was a ten, he told me to come back in 3 weeks, but he told the office to give me one week. I mean, to come back, and, or was it a month? No 3 months, I'm sorry. And gave me one month to come back. But, he gave me medications, that were only good for seven days of pain, and they charged me $34 something for 30 of them, but didn't give me the seven free. And I don't feel that was right. If he was gonna... give me for 7 days, he should have told me. I was, I've been in pain and, I, I really needed the medication.

March 11, 2021
The doctor kept suggesting that I do activities that would make my health worst, according to my infectious diseases specialist. And I kept trying to explain to Dr. David that I'm not I'm not able to do intense activity. I can't do intense physical activity and he kept insisting that I really needed to. And I told him I was aware of this, but this is the way my illness works according to the specialist who has been published and who has done extensive research on the topic. And the doctor just seems to refuse to want to understand that.
March 05, 2021
He is hands down the best provider I have ever had.
