@lsheerin, I want to welcome you to Connect. As a transplant recipient, I am well aware of the stress that you and your husband are experiencing. Regardless of where a patient is being treated, it is possible to run into a care team member who is having a bad day or who does not have a patient friendly personality.

For a transplant patient, the main contact IS your nurse coordinator! Since you are having difficulty with your husband's coordinator, I suggest that you call the social worker in his liver transplant department. Tell him/her what you shared here. He deserves a coordinator who will support him.
Can your husband make the call? Or will you need to call for him?
