Is there a way to scale text responsiveness for mobile?

Hi,
Our site looks awesome on the desktop, but the mobile site has large h2 and h3 titles that are not responsive “enough”. ie. they don’t scale down and repaginate enough. This makes titles look like the attached image.

Also some of the paragraph sections are wrapping oddly. I’d love a way to scale the fonts down more for mobile and ensure words do not get chopped/hyphenated.

Responsiveness is turned on.
Jetpack does not have the mobile theme on.

Site is here

Thanks,
Doug
