Katie O'Brien is the president of the Bills Backers in Houston. She grew up in Kenmore, where Bills football is part of the family.

“My parents actually left me alone on my birthday to go to a Super Bowl that was on my birthday,” she said.

So when she moved to Houston several years ago, she sought out people with a similar passion, and found it at Christian's Tailgate Bar and Grill.

“It's the only bar in Houston where every single TV is on a Bills game with sound,” said O’Brien.

Her phone's been blowing up this week, as she prepares to welcome thousands of the Bills Mafia to her adopted hometown.

“We know that this bar can't accommodate what's coming to town. So a few weeks without telling anyone just in case, we applied for the city permits to shut down the streets,” said O’Brien.

She’s made countless friends through their mutual love for the Bills, perhaps none better than the late Ezra Castro, known to many as superfan Pancho Billa.

Castro was a Texas native, and the two became close, but they had more in common than just their fandom.

“I had my own battle with cancer in 2017 and right when I went into remission is was when Ezra was diagnosed,” said O’Brien.

She survived breast cancer, and welcomed Ezra and his family into her home many times while he was having cancer treatments in Houston. Pancho passed away in May, but left a lasting legacy she’ll always cherish.

“He brings out the best in everyone around him, and the Bills couldn't have been luckier to have him as a fan,” said O’Brien.

And there are constant reminders of that for Bills fans from near and far here in Houston.

“Every year I bring something and add something to bar and last year I put up a bunch of Pancho Power stickers so he will always be here with us,” said O’Brien.

And with Saturday's game here in their home state of Texas, it allows Pancho Billa's young son and daughter to have their first Bills playoff experience.
