My experience with Mass General, Dr. Safa, and his staff, all his staff, [redacted] have been terrific, terrific. They've always been accommodating. They've always answered any questions I've had very timely. And I just can't say enough about them. I'm two years after the transplant and I'm pretty much, you know, in good shape, but they still keep track of me. And I appreciate that very much. So that's it. As far as, you know, they're terrific, absolutely terrific.
