Nadine,
I don't have specific information about high volume spine surgery centers, but in checking with US News and World Report, there are some highly ranked centers specifically for neurology and neurosurgery. For California medical centers national rankings, #2 is UC San Francisco Health, #7 is Cedars Sanai, #12 is UCLA, #21 UC San Diego, and #36 UC Davis. When there is a medical school connected to the facility, there are likely good surgeons there teaching and who present cases and teach at spine conferences.

If you go to the websites for those medical centers, you can start looking up surgeons and their background and areas of interest. You have to research everything you can about them to figure out if they are a good match and look for literature they authored or any videos about them. I understand not wanting to travel, and initially, I thought that was too, but I spent 2 years and struck out with all the surgeons I saw in the closest major Midwest city. I considered both Mayo and Cleveland Clinic, and tried Mayo first and chose to have spine surgery there. Mayo was a 5 hour drive through some pretty countryside for me to get there, and it was well worth it. I returned to Mayo again for surgery after an ankle fracture. When you have a face to face consult with a surgeon, you'll get a much better idea if you feel they are right for your case.

You need a good spine deformity expert no matter where you go, so find the best surgeon you can, and if they happen to be close to home, great, but if not, it is worth traveling to get world class care because you don't want a surgery that isn't successful and doesn't solve the problem you have which now needs revision. I would recommend getting several opinions because it's important. You will likely wait a long time to see a good surgeon, maybe 3 months or more, so you can request appointments with a few now. If you wait to see one, then start with another, it could draw out this process for a year.

Good luck in your quest!
