    Hands down the best Dr visit I ever had in my life. Not kidding. Dr Diaz asked me how I felt during last surgery and just was kind patient honest and I could tell that it was genuine. I listened to him and now we have a plan and Goals for me to receive needed surgery. I cannot keep telling everyone I know how amazing that experience was. To hear a Dr say I am going to help you. Took a money off my chest. It's been a long road of trying all other options no UCSF ortho is where I will be

    Dr. Diaz is by far the most genuine and honest surgeon and doctor and I felt him immensely trustworthy. He explained the risks, benefits, the challenges, complications, but most of all, he listened to me. He paid attention to my fears and my worries and explained things in a manner that didn't dumb them down, but treated me like an intelligent young woman. He made me feel safe and I have no doubt that working towards a solution with him is possible. Thank you so much Dr Diaz!!!

    Dr. Claudio Diaz is such a big asset to UCSF! I will highly recommend him to family and friends if they need surgery that Dr. Diaz could be the possible surgeon.
    Jun 27, 2024
    Care Provider was brief and needed more details but he limited the opportunity. I had a lot of questions unanswered do to multiple concerns so I asked for him back and at least got another potential referral of an associate to get some answers. Time will tell but the delays are a big factor to my demise.
