I get a 404 (page not found) error when I try to access /attorneys or /services via desktop. You may want to consider adding pages for those to improve navigation.
Alternatively you may want to redirect /attorneys to /team/attorneys and / or change the links on your menu to the latter page as I see that page does exist.
I can see sub-pages on desktop.
I can’t easily identify which theme you are using. It actually looks like you may be using a number of page templates.
Normally, if a page shows up on desktop but not on mobile, my first thought would be that the page is using too many resources, but these pages look relatively simple.
So my next guess would be that your theme / templates are not optimized for mobile.
Unfortunately www.remarpro.com does not support commercial products / plugins / themes not hosted here on these forums.
The volunteers here do not have the access to the commercial source code / the code hosted elsewhere.
Please contact the provider of your theme / templates for assistance via their official channels.
On a different matter, your homepage presents accessibility issues because of the half see-through black layer on top (like that you can’t click on any of the items on the main menu).
