Mar 21, 2024
My 10yr old was in ER after seizure. I found Dr. Demus to be very kind. Upon entering the room, he showed me his badge which i thought was a nice gesture. I felt he took time to listen and provide reassurance as we were in vulnerable state.

Board Certifications
What’s a board certification and why is it important that my provider has one?

A board certification represents a provider’s dedication to ongoing training in one or more specialties, including the completion of intensive exams. While not all specialties have board certifications, if your provider does have one they’ve taken the extra step to master their specialty and to keep up with the latest advancements in their field.
