Automatically pull one page from subsites to main site

Hi all
I have a multisite network I’m building where we have a primary site for a healing center. The reason for using multisite is that we want the therapists that work at the center to be able to create their own web sites as part of the community. Now we have multisite all setup and its working fine for all this.
The question I have is regarding finding a way for pulling one page off the child sites to the main site. We want to have a therapists page on the main site that lists each therapist by showing their bio. Each therapist has different skills so we would create tags for each skill and assign to the imported bio pages so people could search for a therapist by skill and then find their way to the therapists child site. Each therapist has a Bio page so I figured we’d pull that into the main site with an RSS feed. I installed a plugin that let me assign a category or tag to a page and just assigned that one page to a new category called therapists. I installed WPMU Autoblog to pull the RSS feed into the main site but for some reason the feed is not working plus this solution requires creating a feed for each child site. I just want to see if anyone has any other suggestions for doing this?
The site is awakeningscommunity.com and is running 3.9
thanks
