Make menu visible on blog posts

is there a way you could make the menu or at least the name of the website visible on blog posts? I'm driving traffic through my blog posts and when visitors enter the site through the post there is no clear identity of the site anywhere to be seen, there is no menu, not even the name of the author of the blog posts.

This really needs to be fixed since it's a major dealbreaker for me. Just having a tag "Return to site" is not enough. Please let me know what can you do about it.
