    Dr. Tay earned my respect years ago when he got a team together to discuss my complex back issue. Years later my old back needs the best neurosurgeon I can find and I've already asked him to decide what to do it and do it. His diagnostic approach is impressive - careful step-by-step aimed at doing the most good with the least risk - for the best longterm results.

    Dr. Tay did my partial discectomy at L4/L5 in 2006 and he did such a great job and is such a great doctor that he was the only one in mind I had when I needed another discectomy at L5/S116 years later. I was so happy to see that he was still on staff at UCSF.
    Aug 08, 2022

    Dr. Tay explained what he was seeing on my X-ray post-op. He carefully explained my options for future surgery Including risks and benefits. He explained my current condition using MRI and a model of the human skeleton. My husband and I understood his explanation and felt very confident in his recommendations and care.

    Dec 14, 2021
    Time was tight and their were a ton of interruptions which make it are to accomplish what I wanted. I did not get through my list of questions nor did anyone look at the provided list of questions concerns.
    Dec 10, 2021

    Oct 24, 2021
    Bad atenci?n from the Doctor to me. I did not expect this bad experience.
    Oct 22, 2021
    Bobby took the time to explain my condition in depth and his use of metaphor helped me finally understand an aspect of my condition that had always escaped me. I have a lot of long term problems with not a lot of solutions but I walked out of the appointment truly happy optimistic and assured that we have a plan of action. I am so thankful that I was referred to Bobby ten years ago. I only wish It had been earlier. I truly believe Bobby has saved my life. He gives me hope for my chronic pain.
    Oct 21, 2021
    Dr. Tay not only explained possible consequences that might arise as a result of the surgery but also gave a point by point explanation of the actions to be taken should any complications arise.
    Oct 21, 2021
    Dr. Tay gave me the information I needed to make an informed decision about the path forward that I wish to take.
    Oct 05, 2021
    Dr. Tay is a "rockstar!" Although I hadn't seen him in four years he was up to date on my situation as if I had seen him yesterday. He was direct when telling me my options even though it isn't always what I wanted to hear and yet he Instilled in me the confidence that he knew exactly the best way to approach and deal with my back problems. He knows a mess when he sees it but still has a plan. I have absolutely no reservations about entrusting him with my future health. He Is also very personable friendly and fun. Call me crazy but I had a good time at a doctor's appointment.
    Sep 16, 2021
    Dr. Tay is the best!!
    Sep 10, 2021
    Unbelievable!!! Dr Tay has been the most amazing doctor I have had. I have had 30 surgeries and this is the most educated I have been prior to a surgery thanks to Dr Tay and the videos were very informative. The service before and after was amazing. The nurses in the hospital were terrific. Dr Mendellis who was working on his fellowship and Dr Garcia we're wonderful kind and very instructive.The care from his staff: Yukon and Keisha and well as everyone associated with the practice went over and above to make me feel comfortable about my 9 and half hour surgery and aftercare.I am now virtually pain free except for healing after enduring 3 years plus of excruciating pain and numbness in my left leg. Thank you thank you all fir bringing me back my life!!!!
