Website with multiple separate sections

> I am struggle to see how I can set this up using WordPress and Elementor.

I’m not clear, which part is the struggle?

– create a Homepage like normal.
– create a top level page called Patients under /patients
– create a top level page called Doctors under /doctors
– create a menu item in the main header called “I AM A” and use a drop down to toggle between Patient and Doctor to link to the appropriate section
– build your all your patient pages under /patients/*
– build your all your doctor pages under /doctors/*

The homepae could be complex, or could simply give the user a choice on where to go like this:

Ahh!
Well that’s a different kettle of fish.
