Hi Dan,
By default, the organizer details should show on the single organizer pages. However, these can sometimes be hidden depending on the theme that you’re using. Just to verify that this is what’s happening, can you try switching to a default theme like Twenty Seventeen to see if the details show up?
I took a look at the page you linked to, and it appears that it is using your theme’s archive template. You can try changing the Events template setting under Events > Settings > Display to “Default events template” to see if that gets the organizer details showing. If not, you can do a customization to add the details in. If you go this route, our themer’s guide and functions list are the place to start!
Please let me know how it goes and if you have any questions.
Thanks,
Jennifer
