Hi Sherri,
We live in Southern California and when my husband was diagnosed with oral cancer we had Kaiser Insurance. I have to say I was impressed with the treatment they gave him. His ENT was in Woodland Hills, but he went for his radiation treatments in L.A.
Now we have Blue Cross and he goes for his follow up check ups through UCLA Medical Center, Head/Neck Dept. They are excellent. You might want to check with them too.
Best of luck,
Shelley
