Dr. Diaz was extremely informative and didn't rush me, he answered all my questions immediately without hesitation. He came across as a very experienced and professional doctor, PIH should be very proud of having Dr. Diaz on their staff.

Yes, I didn't get I did get the the help of my doctor. They sent a lot of people to talk to me and he didn't, he didn't respond.

Dr. Diaz was extremely knowledgeable and helpful. He also listened to my concern and accurately took the processing and the diagnosis of what I had and I highly recommend him to actually be placed as a regular physician. Which I would be more than happy to be one of his patients.

It is always a good experience at this UC. From the registration staff to the MAs RNs and assistants to the providers. Wait times are not unreasonable either.

My experience was fine. There was somewhat of a wait, but that was understandablely due to triage since it was an urgent care center.

Excellent care & quick appointment
July 17, 2021
The staff and doctor always from every department I've ever been to at PH is excellent. What I do wish you would improve upon is your message service and be able to reach my doctor's office directly and not main line. Thank you.

I was very impressed with Dr. Diaz, I go to the Urgent Care, you know, Altadena and this was one of the best treatments I've had since I've been going there for those since your office opened. And I want to say thank you for having such a qualified and inform doctor on staff and a trainer and a patient patient person. And he gave the most Medical Care and my finger is doing much better. Thank you.

No problem and or concerns in regards to medical team, was prompt and effective. The only concern and or unhappiness is with PIH pharmacy. I usually do not use the inhouse pharmacy, this time I decided to give it a try and the wait time was extremely long. Other than that it it always a pleasure visiting PIH.

Best Urgent Care visit ever!
July 05, 2021
Everyone from the front office staff, to the security, to the nurses, to the MA, to the radiologist, to Dr. Diaz, that's great. I was actually there because I was physically attacked walking my dog and robbed and they really calmed me down and help me and got x-rays and got me a brace. They're amazing.
July 05, 2021
Dr. Diaz was the consummate professional. He explained what he was about to do thoroughly and he listened attentively to any questions I had. He definitely put me at ease with a procedure that I was not looking forward to ( the removal of my big toe nail). The execution of this procedure was impeccable and done with very minimal discomfort.

Love the wait time on the website. I waited till it said no wait and came in. I was in and out in less than an hour including waiting for my prescription.
July 03, 2021
Yes, everyone in the office was very pleasant including the person, doing the x-rays, she was extremely nice, and very gentle, and the doctor was very caring appreciated his attention. Thank you.

Went well. Thanks.

Him gone to this place many times I've only been seen in taking in right away this last time, I was taken in. I was given a very far room with number 10. I felt that I was forgotten about. I was in the room for 45 + minutes. When I was told, there was only one, one patient ahead of me, I've never had a providers been more than 10 minutes with me, 15 at the most. So,I don't understand why, you know, 45 minutes was needed for another patient in front of me. Like I said, I believe I was forgotten about and that's what really bothers me the most this time. I was in a lot of pain, I was getting ready to walk out but the provider came in and help me out.

It was fast and I felt very comfortable.

Very grateful for how quickly they saw my son. Everyone who saw him greeted him and wished him well. I hate having a sick boy but I'm happy to bring him to this urgent care for such great care.

Walking in that day, I was nervous and a bit scared. But Jaime Diaz made me feel much better and I wasn't nervous after that. What I like about the experience is that Diaz talked to me throughout the process and was never silent. He made me feel comfortable and the staff was so friendly.

Dr. Jaime Diaz made a very precise assessment and diagnosis that made me at peace and at ease. He was able to check my current prescriptions and gave me a good advice to stop Aspirin which also caused my persistent eye hemorrhage. I was praying ?? for wisdom to be upon him to diagnose correctly and give me the best remedy and he did. Praise GOD ??. Blessings to Dr. J. Diaz and the Urgent Care Staff. ??
