Hi Doug,
There’s a couple things going on here: https://tools.pingdom.com/#!/ersgSw/https://chiropractorgreenville.com/
It looks like W3 Total Cache is taking about 3 seconds to serve your website. I would suggest clearing the cache using that plugin, then disable it.
I’m also seeing a lot of calls to cast_sender.js, which is typically from loading YouTube videos (your site needs to contact YouTube and receive data for each video).
Instead of using a plugin like W3 Total Cache, I would try out some of the methods highlighted here: https://generatepress.com/fastest-wordpress-theme
Let me know if that helps or not 🙂
