How can I set the order of contents in the mobile view?

For example

In the theme "Lawyers" http://themes.muffingroup.com/be/lawyer2/lawyers/
at the desktop view you can see the content (text and image) in alternating left and right.

If I switch to the mobile view than is the left content the first and the right the second. This look not nice.
So, we can see in the example: text - image - image - text - text - image.

Maybe I want to view at first the image and after the text.
The order in mobile view should be: image - text - image - text - image - text

What options to create an individual order I have?

Thanks for help. :-)
