    I lost the ability to walk due to lower spine trauma almost a year ago. Doctor came in told me there was something wrong but not enough to warrant medical intervention physically examined me for 30 seconds prescribed antidepressants and PT told me my disability may be permanent and that I could leave if I did not like the treatment he prescribed and left the room. All in less than 15 minutes.

    This is the second time going to Dr. O'Neill's office and the first visit was very abrupt. It felt like the doctor had something else to do and was very short with his answers. That was the first visit the second visit which was yesterday was even worse he was very dismissive and rude. I know because the first visit was so quick and not very informative. I felt like anything I asked was a wrong question and that I was taking up his valuable time as a patient I waited 2 1/2 months to see Dr. O'Neill because he's the only doctor at UCSF that is able to see Workmen's Comp. Patients and I feel that he may have a different view of the injured worker and with that being not very respectful.

    Dr. O'Neill was so patient and ordered an ultrasound which I had requested but not received from the orthopedic doctor. So grateful he wanted to do this and wanted it at UCSF.

    I just read notes. I think it's poor that drs are clearly required to report how much time they spent with patients. He says 40 min and that may be try if you count my time out of the room getting X-rays and waiting for my Uber.

    Excellent all round

    Great experience. Both the PA and Doctor expressed interest in me as a person not just a patient.

    Dr. O'Neill sees problems far worse than mine all the time so while I would have preferred a little more empathy I can understand why I did not.

    He never went over my MRI and was more concerned about my neck. My visit was a waste of time.
    Mar 25, 2022
    Dr O'Neill was in and out within minutes. Did not empathize with my condition and was quick to deflect my concerns and questions. I was very disappointed in the brief and superficial appointment especially as I had waited two months to consult him as well as drove multiple hours to reach the clinic.Very disappointed

    Overall excellent care by the provider. The only thing I would suggest is for him to have a better monitor/camera set up for evisits. His camera was apparently on a different screen than where my Image was displayed so the entire time of the visit he was looking away from me. Kind of distracting. That can be easily remedied.
