Blue business card with contact info found

I found a blue 3.5x2 inch business card this afternoon around 2:15pm on the sidewalk outside the Carnegie-Stout Public Library on West 11th Street in Dubuque. The card is for Harbor Ridge Wellness, with a white wave logo and a phone number ending in 4211, plus an email address that's smudged. The back has a neat handwritten note: 'Ask for Mara' in cursive. There’s a subtle coffee stain along the bottom edge and a small crease on the corner, but otherwise it’s in decent shape. I’d love to get it back to the owner—this looks important and I hate the idea of someone losing their contact. If you know who this belongs to, shoot me a message here.
