I am local to LA. When I was first diagnosed, I made an appt to meet with Dr. Schwartz directly rather than doing through phone. I had my surgery on 8/5/14. I know the last two months due to summer holidays they have been quite short staffed on the surgeons. Dr. Schwartz is on vacation for one month (they really need their breaks). Dr. Lekovic was on vacation for one month during my surgery and is now back. Dr. Slattery was out for a week. Those are only the docs that I knew so I'm assuming the other docs are in and out as well. I don't know if this will work, but you might try calling one of the doc's secretary directly and see if they are in town and can look at your file?
I wouldn't give up on them. They are so good with AN surgery. Once you are there, you get their experience and expertise, and all of their nurses know exactly how to care for you.
