@cares4him, Good Morning, and Welcome to Connect.
I have located the following links that will give you information about paired kidney donation at Mayo Clinic. You will see that Mayo operates in 3 states and they are able to work closely with each other to provide exceptionally good results with matching a recipient to the best matched donor kidney.

I received my organ transplant at Mayo in Rochester in 2009. It was a simultaneous liver and kidney transplant ( both organs from same deceased donor) . I am extremely confident that Mayo has the expertise and the ability to guide you through your transplant journey.

It sounds as if your partner is already listed for a kidney else where (?). Please know that you can contact Mayo by using the contact information that is included in the Kidney Transplant Program link.

Where are you and the donor located?
