Taking posts from a seperate WordPress Page

I have someone who has a wordpress account, and i want to take his posts, for them to appear on a page in my wordpress site. Preferrably not using RSS. Is this possible? Essentially i don’t want to give him access to the back of house of my site, instead take his blog that he is already actively using and have his posts also show up on a page in my site. That way i have no security issues, and he doesn’t need to change his blog information and lose visitors.

Is this at all possible?
