Upfront/Spirit - Making certain text small on the same line

Greetings!
How could I make some text on the same line in a text element smaller without effecting the other text on that line?

For example, in the screenshot, I'd like to make the "TM" symbol smaller (paragraph) than the title text there (heading 2). Or in some way just make the tm display smaller on that screen.

The page I'm referring to is tamanasprings.com/spark

Thank you guys for the assistance!

Much Love,
Ciro Bey
