My T does not discuss anything with my MD unless I request it (and only then after we agree it would help.) IF you say you do NOT want then to discuss you without your knowledge, they must honor this... but you probably have to put it in writing (thus cancelling anything you might have signed..) I'm sure any agreement had to be disclosed... but you may have to look through a lot of college papers to find the agreement! Good wishes. Hopefully, both of the doctors would work together to help you, as they are part of YOUR team, right?
