How Do I Find GI Spec. Who Does Endocinch/Plicator?

I'd love to have the Nissen, but I can't due to motility problems.  If I were to alter the shape of my stomach, it might make the motility issue even worse.
 
Therefore, I need to find a GI specialist in the LA region who has done a lot of Plicator and Endocinch procudures.  I did a search on Dogpile, but no hits.  Any suggestions on how to find someone who meets the above criteria?
 
Gracias,
Laura
Aha!  Well, I found the doc list for my area for Endocinch, but still wondering about Picator . . .
