How to scrap child classes in R?

I am trying to extract some information from the following link: https://www.alaha.org/resources/hospital-directory/ I need some piece of R code to go to each hospital and extract County, Mailing City, Hospital Phone, Website, Media Contact, Contact Phone and Contact Email information.

I have tried everything within my reach but I could not figure it out how to extract child classes in R (assuming the problem as child classes, but I might be wrong, I don't know HTML).

Any help is appreciated. Thanks!
