Susan, Marc says the only one he knows is Rola Mahmoud. I looked her up, she's published on both brain and spinal MS, and she's accepting new patients, she's out of St. Luke's KCMO https://doctors.saintlukeskc.org/provider/Rola+...
I might be able to help with this. I'm from KC and I have a childhood friend who's an ER doc at St. Luke's on the Kansas side, but he may know someone.
