Let's make this birthday one to remember.

37 years old (Born on November 13, 1987)

Happy Birthday, Dana Vollmer! From making waves in Athens back in 2004 to soaring through the water like a butterfly (literally!) for gold at London’s 2012 Olympics, you've always known how to make quite the splash. Your incredible speed and determination have inspired swimmers everywhere—and probably scared off any actual butterflies from challenging you.

Here's hoping your birthday is as legendary as that record-breaking swim of yours. May your celebrations be filled with laughter, joy, and cake—because let's face it: after swimming faster than most people can run on land, you've definitely earned an extra slice or two!
