I can confirm this, I had a 3cm AN removed at UCSD Jacobs Medical Center by Drs. Schwartz and Friedman. Surgery itself was a fantastic experience minus a few bumps in the road. The bumps were mostly due to my being one of the early AN patients at a new facility where supporting medical staff were not quite used to the carefully choreographed 'dance' of veterans like Schwartz and Friedman.
I hope and expect to begin documenting my experiences more formally soon from the scraps of paper, emails and photos to myself, etc. I'm very much still in recovery which is going on the "better than average" side of things, but far from perfect still. However, none of that detracts from the fantastic work this duo and their team did at UCSD before, during and after the procedure.
If you have doubts, do some research on them both. They're renowned for a reason and my experience backs that up in spades. Friedman remains the ONLY doctor of any discipline who has truly been "available" when I needed advice. From the first time I reached out until recently with a recovery question, he gets back to you SO quickly, it shames pretty much every other medical professional by comparison.
