On the Doctors page you can control the text (as displayed here) to give general information about the doctor(s), their training and experience.
At your option you may also add information on individual doctors as shown below. The administration section has a form where you add the name, title and biographical text as well as upload a picture. For two location practices, as how this demo is set up, there are controls that allow you to display at which location(s) a doctor works.
The doctor record controls also allow you to change the order in which the doctors are displayed.
