Hi @ahtaylor and welcome to the NETs group. I'm glad you joined us here as well as the Diabetes/Endocrine group.
If you read this discussion thread -- Carcinoid http://mayocl.in/2j1tL0M --, you'll get to know pretty much everyone participating in the group. I'm specifically tagging @gaylejean on this conversation as she may be able to share a bit more about what you can expect at Mayo Clinic, although I don't know if she had insulinoma testing. I'm also bringing @ridgerunner in as she manages hypoglycemia.

AHTaylor, you mention "I have walked down this path once already." What did you mean by that?
