Sharing the Expertise: Doc to Doc Directory

Physicians wishing to connect with other doctors experienced with the complexities, multiple issues, and multiple presentations of atypical hemolytic uremic syndrome (aHUS) are encouraged to contact these volunteer physicians.

Patients, parents, and caregivers can share these physician contacts with their care teams by emailing this directory page. Your care team can then reach out to these volunteer physicians regarding aHUS diagnosis, treatment, and disease management.


Physicans listed here keep busy schedules, so please respect that time limitations will not allow them to take individual patient phone calls or to answer patient emails. This directory is intended for physician-to-physician contact only.
