I think the website is pretty snazzy and is illustrative. Is this a WordPress template? If so, would you recommend any managed WordPress hosting site - WpEngine? Our performance on Siteground with Cloudflare has been less than stellar.

Not OP but also I've heard Cloudways is good for managed WP hosting https://www.cloudways.com/en/

I've used WPEngine and haven't experienced much issue myself. Their support has been good and pretty helpful with managing tricky mysql situations.

yes it is a wordpress template. it is hosted in azure. so far it's holding up - even with frontpage HN traffic.

I have used dreamhost for other sites but the performance is so-so... Not bad but not great either...

another option but more hands on is a digital ocean droplet - it's also a little more pricey.
