If I may....
Indeed our component has only common administrator editor, it was not built as each doctor page profile editor.
For you purpose I suggest those options:
- Suggested by Toufiq, based on Articles, then you can use Joomla ACL, or
- external directory/catalog component (premium), or
- Custom component (but too expensive) or
- SP Medical code customization (less expensive than 3).
then each doctor can have its own profile page, and will be able to edit only his page.

I do not hide the fact that (2 or 1) will require a few(a dozen) hours of work, but in the end it will be a very flexible solution. And over a longer period of time, you will definitely find that this will allow you to add new fields or payment for highlighting a doctor on the list.
