Mid wife vs gynecologist

Carly • Mom of two boys and teacher! Busy and tired
I have a question about midwives really. My doctor just passed away in some freak paddle boarding accident and because of this they have set me up with a mid wife for my 24 week appointment in hopes that I stay with her for the rest of my pregnancy. I'm just curious what the pros or cons are of a mid wife and what are the differences?
