Custom font for title of card block

Hi- 

I am using a custom font on my page, but can't figure out the code for the title of a card block I have. 

https://www.maliawellness.com/ I'm trying to change the "My Services" title.

Can anyone help with this?

Thanks!

Thank you @Lesum ,  that worked!

I'm also looking for the code names for my blog titles and the blog card titles- is there a resource that lists these CSS codes? 

@cmalia With blog titles, use this CSS code

h1.blog-title a, h1.entry-title {
    font-family: 'Coldiac' !important;
}
