PA-C David Cao is very professional and personable; felt very comfortable in his, in the absence of Dr. (name removed).
June 16, 2026
He explains things and keeps it simple. His warm personality and knowledge makes him a great doctor. His staff is so friendly and also knowledgeable. Makes you want to come back!!
June 12, 2026
I did not trust this PA at all. He didn't have any answers for me. He was not aware of, he was not informed of my case. He wasn't able to find the MRI that I had done like a few weeks ago. He was not helpful at all. And I did not trust this person at all. I will not, I will not be seeing him in the future. I was very, very disappointed with the service that he provided. Thank you. Bye-bye.
June 11, 2026
Yes, the doctor is Dr. Cao and I'm very pleased with him and will always go to see him. He's very understanding and patient.
June 11, 2026
I described some worsening pain so David Cao arranged for unscheduled X Rays during my visit. This vas very convenient and vill accelerate my diagnosis.
June 10, 2026
I did not have a positive experience. The PA was not prepared before I walked into the office and spent most of the time staring at his screen. Almost no real interaction with me to understand my current pain and possible ways to address them today. Bed side manner skills need to improve
June 08, 2026
Dr Cao is always polite, on time, he also has a great ear for listening ti me w/my issues. The best pain medicación professional that I've dealt with in many many years.
June 04, 2026
He explained everything very good I would come back again with him.
June 02, 2026
Entire staff very professional
June 01, 2026
David was very prompt. His nurses were also very prompt, very educated and kind to me and my mom as we sat in the doctor's office waiting for the visit. His nurse was so polite, took all our information down, also gave us feedback for what she thought would be better for me. Also, when the doctor came in, he gave me some really good advice, really well planned, discreet about everything, very detailed down to the bone. I mean, me and my mom left that office with sheer confidence that when or if we ever go back to him again, it'll be a smooth, comfortable, like riding on a cloud experience. Thank you. Have a nice day.
May 28, 2026
Arrived on time and waited 30 mins to be called
May 22, 2026
With Dr. David Coa, I've been seeing him for several years, actually, actually more than five. He is an excellent physician. I don't know what I would be or do without him. Actually, he's taking care of my problem, listens to me, cares about me, and is always there as a doctor. I appreciate it. I'm going to miss him if I move to Georgia, but he's a great doctor. Please keep him, PIH.
May 18, 2026
Dr. Cao is very professional. Thank you very much.

The kindness of the nurse and the doctor.
April 14, 2026
Hey, David Coa is, he always has a lot of respect for you. I like him a lot. I have been to a lot of doctors and nurse practitioners and he's awesome. You guys need to give him a raise. All right. Thank you and bye-bye.
March 24, 2026
My husband and I both go to Dr. David Cowell and we like him, we're satisfied with his care, but we both wanted to tell you that his, I don't know what you call her, his assistant, her name is Gezi, she is just above and beyond any assistant we've come in contact with in all the time we've spent at Presbyterian. So I just would like somebody to know that she just really tries extra hard to help her patients. And me especially, I need a ride because of my wheelchair and she works to get me a ride from Presbyterian travel. I don't know what they call it, travel, what they call it, but they come and pick me up and take me to my apartment both ways and that is just extremely helpful. So.
March 24, 2026
This was my first time being seen by Dr Cao. He and (name removed) were pleasant, courteous and professional. (Name removed) escorted me to the exam room, went over my medical history and took vitals. She had a very welcoming personality that instantly put me at ease. Dr. Cao reviewed my health records, discussed medical issues, and explained available options. I was very pleased with this visit.
March 23, 2026
Thank you for answering the medical condition that I have that I was concerned about.
March 11, 2026
After having an MRI for back pain, I came into the office and he was not aware of the MRI or what was going on with my back told me to go to the portal to find out he was uninformed. I felt unheard he was offering me medicines or therapy where if he'd read the file, the doctor already gave me medicines for when my back was acting up, kind of a waste of time.
March 06, 2026
Dr Cao was very helpful and listened to what my problem was and helped me with it. He was effecient and caring, as well as the staff . They were all nice and helpful as well.
March 05, 2026
Office staff, very professional, very kind. Dr. Cao listens, cares. Definitely recommend him. Thank you.
March 05, 2026
Got in early, X-Ray was fast, went over results same visit. Fantastic
March 05, 2026
During my recent visit, I had a very disappointing and uncomfortable experience with this doctor. From the beginning of the appointment, his demeanor felt dismissive, sarcastic, and unprofessional. Instead of listening to my concerns with care and respect, I felt as though he minimized what I was experiencing and made me feel as if my questions and symptoms were not important. I came to the appointment seeking medical guidance regarding symptoms and pain I have been experiencing. Unfortunately, I did not feel heard. When I attempted to explain my concerns, the doctor responded in a way that felt condescending and sarcastic, which made the interaction uncomfortable. As a patient, it is already difficult to discuss personal health issues, and the tone used during this appointment made me feel disrespected and discouraged from asking further questions. What was most concerning was that I left the appointment without receiving any meaningful medical advice or guidance. My symptoms and concerns were largely dismissed rather than properly discussed or evaluated. I expected a professional conversation about possible causes, next steps, or recommendations, but instead felt that my concerns were brushed aside. Healthcare providers should create an environment where patients feel comfortable discussing their symptoms and asking questions. Unfortunately, this experience did not reflect that standard. Patients deserve to feel respected, heard, and taken seriously when seeking medical care. Because of how this interaction was handled, I would like this review to also serve as a formal complaint regarding the doctor's conduct during my visit. I believe professionalism, respectful communication, and attentiveness to patient concerns are essential parts of medical care, and my experience did not meet those expectations. I hope this feedback is taken seriously so that future patients do not have a similar experience. Every patient deserves to feel that their concerns matter and that their healthcare provider is genuinely listening and willing to help.
February 25, 2026
The only reason I'm staying here is that I receive good care. It's just that the appointments are scheduled very far in advance, and I have chronic illnesses. I'm older now. I would like the appointments to be scheduled a little sooner than the three months or more it currently takes. That's my opinion.
February 25, 2026
Dr. Cao is an excellent doctor and so did people that work with him over there. So I'm very, very happy with how they're so nice and polite and very respectful. Thank you.
February 02, 2026
The doctor seemed in a hurry. I had to reschedule a prior appt because l had just had surgery and he gave me the feeling that was not a good reason for rescheduling. He kept scanning his computer while we talked and l just felt he was not really that interested. I was in and out of his office in10 minutes.
January 30, 2026
David Cao is EXCELLENT! thank you for the injections to ease my pain
January 29, 2026
Staff and Doctor were great!
January 27, 2026

January 27, 2026
I'm very thankful that he's my doctor and he is wonderful and I'm glad he helps me a lot all the time. Thank you.
January 20, 2026
Dr. Chow was very thorough about explaining what my mom, (PHI removed), needed to do to help with her pain management and how she needed to do it. He was very compassionate and we will be seeing him again. Thank you very much.
January 15, 2026
I like this office staff and provider they are very nice I think sometimes when I'm there I feel that I say the same things every visit. That it's all chalked up to age and size.
January 12, 2026
Everything was great. The doctor was very attentive, and the nurses were very helpful. Regarding the time, I did have to wait a little longer than the appointment time, because I think if you schedule an appointment, you should be seen at the scheduled time. But everything else was perfect. Thank you very much.
January 08, 2026
I think (INAUDIBLE) is a individual and very thankful and she listen to what I have to say. I give her an A+.
January 02, 2026
I like the doctor. I liked his staff. It was very, he's very knowledgeable.
December 29, 2025
Experience was fine as always. Hard to get on any PIH dr's calendar in a timely manner.
December 19, 2025
I have been seen by David Cao for some years now. He is kind, attentive and is an excellent example of what a health care provider should be. His staff is above and beyond in their customer service. If this means anything to anyone then David Cao and his staff should be recognized and rewarded. (PHI removed)
December 17, 2025
I am 100% happy with my pain management Dr. CAO. It was the best decision (besides my engagement to my love) that I made and I count my blessings everytime I make an appt to see him.
December 16, 2025
I feel like my provider wasn't paying attention to my needs
December 11, 2025
(Name removed), his assistant, is awesome, polite, thorough, and David is always wanting to know everything and checks you and tells you everything you need to know. And everything I said that was a four, I meant it. I wasn't just pushing buttons. Thank you.
December 10, 2025
I've been going there for 10 years and seeing Dr. Cao and it's been a great experience. Thank you.
December 09, 2025
Appointment was on time. David Cao asked pertinent questions and listened. Was there to have prescriptions renewed. Everything was done in a timely manner.
December 08, 2025
An amazing time. It was timely and in order. There's nothing else to say. PI-8-10.
December 08, 2025
As usual, David, my PA, he's wonderful. So is Dr. (name removed). I always give you guys high scores because you deserve it, and so are the staff when you walk in the office. They're just as sweet. All right. Thank you. Bye.
December 08, 2025
I am very blessed to have Dr Cao as my pain management physician. I truly appreciate all the support and effort he provides to better myself and ease my pain. Dr Cao goes out of his way explaining me, on every option and situation that affects quality of life, and I'm grateful for it. I strongly believe that PIH has an extraordinary Dr in their staff and a great asset in their team, and hopefully, for many years to come.
December 02, 2025
Dr. Cao, he is a great doctor. He always spends time and explains everything to me. I have no complaints with Dr. Cao, and his office staff is great.
November 21, 2025
You guys always treat me like a king. No, you guys, everybody there is so nice and sweet to me. I never have no problems with anybody in that hospital or in that clinic. My Dr. David, he's really cool. And (name removed) is another good one, too. Don't complain from me. Everything's good on my side of the fence. May you guys have a happy Thanksgiving.
November 20, 2025
I don't think I was understood how much pain I was in and I'm not any better after 5 days of medication
November 17, 2025
Hello, I am so appreciative of Dr. Cao. He always makes me feel safe and listened to. He's always professional. He's empathetic. He does his job. He does it well and he's very, very courteous, always, always, very courteous and doesn't make you feel like he's rushing through your appointment. He feels like... It always feels like everything was handled and that he's always, always there. If you ever have any problems or anything, he doesn't, don't hesitate to reach out. And I appreciate it. So, and happy holidays. Thank you. Bye-bye.
November 14, 2025
Excellent bed side manner
November 12, 2025
I fully trust the care that Dr. Cao provides me with and am grateful for his expertise.
November 07, 2025
The staff is always very professional and kind. And as far as David Cao is concerned, he's excellent. He's helped me have a productive life to deal with my pain. His recommendations and his thoughtfulness has helped me work through it, and I always follow what he tells me. He's awesome.
November 05, 2025
My experience with Dave Cao was somewhat frustrating when explaining the history of the pain that I had in my upper quadrant wrapped around my back. He seemed to be bucking heads when we talked about my experience in the ER and giving at least three cardiac workups. He was asking me about my history and when I explained to him the importance of all my doctors ruling out my heart, I tried to make that really clear and he seemed ?
October 30, 2025
Waiting for surgery scheduling to call me. That appointment that I had was a waste of time. They could have done that over the phone. Anyways, it was unnecessary, but someone please call me from surgery scheduling for my injection, please.
October 30, 2025
You can improve by having Dr. Coa not put his head down and act like you're bothering him when you have an appointment with him and are called in his office and you think he's going to talk with you and he's looking down and he's acting like literally you're bothering him. It's rude. He's rude.
October 27, 2025
I just have to say that every doctor I have through PIH, HealthNet, Molina, they have been the best doctors I've ever dealt with in my entire life, but especially Dr. Coa because he listens and he understands and it's just, it's so easy to talk to him.
October 27, 2025
I was treated with care. I was respected. I also was respectful. I have no complaints. I would recommend people to go there. He's friendly. He's humorous. He has great qualities. Thank you.
October 27, 2025
I really like the service.
October 17, 2025
David always answers my questions and cares about your well being
October 14, 2025
Yes, I love Dr. David Cao nurse, Dev. She always listens. She always cares about, feels like she really cares about me personally. And also David Cowell, he listens to everything and tries to make me feel better and ways I can improve my pain management. Thank you.
October 13, 2025
I've had nothing but great experiences with this doctor. He's really good. The staff has always been fantastic. I've never had any problems. They're phenomenal. I would definitely recommend him. He's a great doctor. Staff is fantastic. Like I said, never no problem. So they're just great all the way around. There's nothing wrong. They're awesome. Thank you.
October 07, 2025
My doctor is Dr. (name removed) and I'm extremely happy with him and plan on using him indefinitely.
October 06, 2025
Maybe get a bigger parking lot? Parking was very difficult.
October 06, 2025
David Cao is very helpful in guiding my care plan.
October 01, 2025
David is always attentive, caring and professional. I highly recommend him!!
October 01, 2025
Dr. Cao is the best, office Staff is the best. M.A. that took care of me on this day Is the Best. Thank You
September 30, 2025
This visit was a check the box visit. It was nothing more than that. He was spending the time filling in the blanks in his laptop. Basically asked me to stand and show where I was having pain. The rest of the time his eyes were on the laptop. Just a formality to receive another epidural. Other issues kept me from getting in when I really needed to. The time in between went to long. Nothing personal about the PA. To me it was more clerical, not medical.

Dr David Cao took good interest in my needs
September 12, 2025
Just because an additional ailment isn't in the doctors notes, doesn't mean the patient doesn't have problem also. He did not see neuropathy in the notes. I know I have it with my diabetes of 25 years
September 02, 2025
Over there top amazing. PA Cao Great PA. Kind caring listen gets the best game plan understands the pain and discomfort. Good human being. His nurses amazing. (Name removed) wow what a ray of sunshine so helpful personable. We love the office
August 26, 2025
Hello. The waiting time was too long. And then when we saw the doctor, he was very rude and he wasn't understanding. And I felt very uncomfortable with him.
August 26, 2025
And Dr. Chow, I met, I guess, as a PA, was very unconcerned, felt like he was not listening, paying attention, or even that I was in the same room with him. I was very unhappy. Thank you.
August 25, 2025
Okay, I believe all the doctors at PIH are fantastic. I've been dealing with them for quite a few years, and I really love the hospital, the doctors, and nurses, everybody who works in there. Thank you so much for letting me talk about him, especially Dr. (name removed). Dr. (name removed), and my pain management doctor. Sorry, I don't remember the name. Okay, beautiful day. Thank you. Bye-bye.
August 25, 2025
Continue with a good costumer service very kind thank
August 22, 2025
Yeah, David Cao, he's been my provider for, I think, gosh, almost two years. He's awesome. He's just really a great guy, really super knowledgeable. And, you know, I just feel comfortable. I feel comfortable with all the PIH, but he's just a really smart guy. I would give him a raise if I were you. Anyway, thank you very much. Bye-bye.
August 20, 2025
Dr Cao was great, along with the nurse!
August 06, 2025
The PA spent a great deal of time typing on his computer but didn't share anything with me. He barely looked up at me. I would like to know what all the key strokes were. Barely heard 3-4 sentences from him. I understand the need to record the visit but how about sharing what you are typing. And some eye contact. Desi was so personable. Great smile, helpful. She made me smile.
July 30, 2025
David and the staff are great. It would be wonderful if you eliminated the parking fee or just validate patient's parking.
July 29, 2025
I would like there to be someone who could translate from Spanish to English and English to spanish, since many of us don't clearly understand what is said to us in English. So that would be a fundamental part for people when we are older and even those with pain and who don't understand the words that are said to them very well. So it would be good if there was always someone who speaks Spanish who could translate for us. That's the only thing because...
July 29, 2025
Great service from all the employees and Doctor!
July 22, 2025
The PA had horrible bed side manner. I feel he did not listen to me was only writing in the laptop and didn't help. I was in excruciating pain and I felt he was no help and rude and just closed his laptop and walked away at the end.
July 22, 2025
Dr. David Chow is a great doctor
