The Marine veteran, who survived two tours in Iraq, left behind his wife Lynsay and their children, Kadence and Brad Jr.
His family makes sure to always remember the fallen officer on his birthday.
In a Facebook post, the family writes, "Another year has passed and our tradition of sending daddy balloons in heaven has continued."
In the video, Kadence and Brad Jr. sing 'Happy Birthday' to their dad and then send balloons up to the sky.
When asked where the balloons are going, Kadence says, "They're going to Daddy."
The kids then blow kisses up to their father.
"Catch it, Daddy," his daughter says.
