Hi Dennis! Having a care team at the Mayo Clinic is pretty amazing isn’t it? It’s something people have to experience for themselves to completely understand.
It’s wonderful that your wife had an outstanding nurse in Jacki! This online forum, while backed by Mayo Clinic, isn’t connected in that we aren’t able to contact anyone at the clinic personally.

What you can do is write directly to the clinic at this address:

Methodist Hospital
5th floor. (5-201). (Attention Nurse Jacki)
200 First Street SW
Rochester, Minnesota 55905

The note will get to the main desk on that floor and from there, it will get to Jacki. You can put a note inside the envelope giving the room number and the date your wife was there to narrow down the correct nurse on duty. You could try to contact the desk on that floor too but they won’t give you Jacki’s last name.

There’s an opportunity in our forum to nominate a nurse for a DAISY award for outstanding service! https://connect.mayoclinic.org/discussion/nominate-a-mayo-clinic-rochester-nurse-for-a-daisy-award/

Does your wife have any follow up appointments? That might give you a chance to take something directly to that floor…for Jacki or all the nurses!
