I think I found Dr. Fuller by searching something along the lines of "Los Angeles TOS Vascular Surgeon".

I just got back from his office and had a very different experience. He said that he doesn't have enough information to conclude TOS. He did not look at any of my imaging and instead kept insisting on reports only- I didn't have my brachial plexus MRI report with me, just the CD. Also, his exam of me lasted about 30 seconds and did not believe he found anything, compared with Dr. Brown's half hour that he spent with me leading him to in fact find something. Upon leaving, he told me to send him my reports and also my MR Neurography report after I get it done this Friday. I won't be returning.

Tomorrow I'm seeing USC Vascular surgeon Dr. Fred Weaver. My orthopedic doctor sent me to him after I sent him an e-mail yesterday with my new diagnosis from Dr. Brown.
