Your website is looking good! It is loading pretty quick for me - less than 1 second on average. I ran your site through Pingdom (tools.pingdom.com), GTMetrix (https://gtmetrix.com/) and Google PageSpeed Insights (PageSpeed Insights) a few times.
Oddly, the thing that consistently took the longest to load (relative to its size) was the Google Tag Manager script. Assuming you are serving that on purpose (using Google Marketing), so not much you can do there. You are also serving an empty style.css file that you could remove (if you aren’t going to do any custom CSS).
I’m not seeing any reference to Bunker JS loading from the client side. There is popper.min.js, which is used by Bootstrap.
What kind of load times are you seeing?
