Let's make this birthday one to remember.

61 years old (Born on February 17, 1964)

Happy Birthday, Mark! Another year wiser, and you're still rocking the Kennedy charm with style. Your tireless dedication—from championing children's education through Save the Children to your outstanding efforts in public service—keeps reminding us you're much more than just another legendary family name.

Whether delivering heartfelt speeches or launching innovative community initiatives, you've made a lasting impact that strengthens communities far beyond Maryland. But don't let success go to your head—you're already part of America's most famous political dynasty. May this birthday mark (pun fully intended!) another memorable chapter in your ongoing saga of laughter and meaningful change!
