    My experience is this: when you interact with people at the top of the scale, you get the best possible treatment. Even though Dr. Cosgrove is so much at the top, he spent careful, sensitive, intelligent time with me, and explained things about my brain that no one has before. I feel so fortunate to have seen him.

    He seemed rather rushed, he was nice enough but he made the PA meet with me first instead of himself which would have saved a lot of time because I answered the same things twice. And there was no real communication or explanation of what he wanted to do versus what I wanted done.

    The provider directed a lot of his commentary to the resident. My husband didn't feel like he was talking directly to him. In terms of medical knowledge no complaints.
