Dr. Mathier speaks in a clear and concise manner.Jennifer does this as well. I trust both of them and their plan of action to find out my problems and correct them.

Dr. Michael Mathier is the most compassionate, caring, capable physician I have EVER had during my decade of serious illness. His lexicon is always easy to understand while never feeling as though you are being talked down to. He educates and always listens and never rushes. I don't know where I would be without him.
