I know this is an old post, but if anyone out there is looking for a great doc at UCLA, go see Dr. David Yu. He is an AS researcher. He looked at a basic back xray and diagnosed me within 30 seconds (something my loser rheum refused to consider, wanting me to deal with NSAIDs and come in every month for bloodwork using his in-house lab instead) Dr. Yu's staff then set me up for at-home remicade infusions with a nursing service and worked out the insurance issues. He doesn't really do regular visits or long-term care, but if you are looking for a definitive diagnosis, he is your man!
