I'm in MN, so always interested in goings-on in the general upper Midwest. I am not aware of any docs in Wisconsin currently testing or treating but hope you can get one started. Do you have all the information you need for contacting them? There's a website with all possible IRs for every state. And the research sticky here is useful if you want to include Dr. Zamboni's endovascular treatment research or something else. Best wishes. Every doc we have was found by someone doing the legwork.
