Dear caseydan:
Welcome to our SCLS community!
In the "Disorder Details" and "Disorder Resources" pages of this site, you and -- most importantly -- your doctors will find just about all the information that is available, so if you haven't read them, printed them out, and/or emailed them to your doctors, please do so ASAP. If you'd like to receive any of the articles listed under "Disorder Resources," email me at _aporzeca@american.edu_
As to your question, it is correct and a shame that, following last year's retirement of Dr. Philip Greipp, right now at the entire Mayo Clinic there isn't a single doctor who has shown an interest in being supportive of this community or its patients.
Besides, the Mayo Clinic has not been at the forefront of research on SCLS, and you can't run to the Mayo Clinic from Missouri if and when you have an episode of SCLS. You need to find and develop a relationship with the best doctors in the vicinity of where you live -- including with a senior internal medicine physician, a hematologist, and an immunologist, preferably ones that are affiliated with a medical school or major medical center.
The most important thing for you to do is to have whoever diagnosed you with SCLS, or is your primary physician, get in touch first and foremost with Dr. Kirk Druey at the National Institutes of Health, see contact details under "Disorder Details." He can be helpful in confirming the diagnosis and in answering questions your doctor(s) may have about how to proceed.
Moreover, if you are willing and able to travel, your physician should arrange for you to be examined and tested at NIH, which is located in the outskirts of Washington DC.
