This was my first meeting with Dr Usher, as my previous MS physician left the practice. I found him extremely caring and interested in how I was feeling. He took a detailed history of my ms journey and explained possible adjustments to my medication, if needed.

I believe the Dr heard me say a lot of different information, on some there was commiseration, but not an actionable plan.
