BYU athletic director Tom Holmoe is famous for going all-in each year when he dresses up for Halloween.

He conjured up another winner this year, dressing up to the nines as the wise old Hogwarts headmaster Albus Dumbledore from the “Harry Potter” series.

Other Halloween costumes that Holmoe has summoned up over the years include playing Dumbledore’s rival, Lord Voldemort, as well as portraying Abraham Lincoln, the Mad Hatter and the Genie from Disney’s “Aladdin,” among others.

Inside how BYU AD Tom Holmoe’s Halloween costumes come together

Last year, BYU released a video feature showing just how much time and detail go into selecting and executing each year’s Halloween costume.

“I’m just a kid at heart on Halloween,” Holmoe said.

His Halloween costumes are popular among the BYU and college athletics communities.
