To my knowledge and according to House's website, they have two neurosurgeons, Dr. Schwartz and Dr. Lekovic, so one or the other of them does tumor removal. They have 8 neurotologists on staff. The ones you hear the most about with tumor removal are Brackmann, Friedman, House, Luxford, Slattery, and Wilkinson. Again, to my knowledge either of the two neurosurgeons can be paired with any of the neurotologists on staff for each surgery scheduled.
Which two are paired together depends on a number of things, but the schedule of each physician is probably the biggest decision, followed by patient preference. So, yes, Dr. Friedman and Dr. Schwartz still work together.
Since House is sponsoring the biennial ANA Symposium in Los Angeles in August, their operating schedules will probably be somewhat shortened during that week of the Symposium.
If you feel strongly you want the Friedman/Schwartz team, you need to contact House and/or Dr. Friedman and express your preference ..... remember, it could mean waiting longer for their schedules to mesh.
Best thoughts .....
