Since this was posted 2 years ago, I'm assuming that you've gotten the information you needed by now! :) But for anyone else who's using this as research like I am, we were soooo happy with Dr. Mehendale. We used him for my son's swollen neck. It turned out to be mycobacterium that needed to be removed with surgery. He's great! The surgery was very tricky because the masses were right on a major nerve that controls facial movement, so if a wrong move was made, he could end up permanently facially paralyzed. Super scary, but he did great and my son's doing fine now.
Also, if you Google Dr. Mehendale, you'll see so many glowing responses from other parents, too.
