About Marianne Nellis, M.D., M.S.

Personal Statement

I specialize in the care of the critically ill child. Though it is a difficult time and involves complex care, my goal is to make the experience of a child in our ICU and their family as smooth as possible. This is accomplished through compassionate care and frequent communication. In addition, through my research endeavors, I hope to make the transfusion of blood products to children as safe as possible.
