APSFA Find a Doctor List

With the help of our Medical Advisory team our forum members & other APS patients, we have compiled a list of doctors who are familiar with APS and who currently treat APS patients. We're always looking for more doctors to add to our list. If you want to add your doctor or find a doctor that needs to be removed from our list, please use the form on our contact us page. For a list of Doctors outside of the USA, please see our Downloads page.

The APSFA does not endorse any of these doctors, they were simply suggested to us by others.  The doctors on this list may not be "experts" in APS, but someone along the way has had luck with them.  You may not have the same luck.  Please be sure to call the office to ensure that the doctor will take your health insurance and is accepting new patients.

Click on a State on the Map to view Doctors within that State. Doctors are organized Alphabetically within each Specialty.
