I have Kaiser in VA. After 2 high 24 hour cortisol tests, my endocrinologist referred me to NIH. I am not sure that Kaiser has the expertise in house to effectively diagnose and treat Cushings. That said, my Kaiser accupuncturist is the one who tested my DHEA, which was nonexistent and referred me to the endocrinologist.
Maybe he could contact my endocrinologist at Kaiser and see what he says - Dr T Lee in Falls Church, VA. NIH treatment is free except for the transportation.
