He popped into his local grocery store, picked up a small cake and a candle with the number "3" on it.
Then, in a "small family gathering", the Sereno family marked the pothole's three-month birthday.
He then posted photos to his local Facebook group.
City officials blame the weather on the fact that the pothole had not been fixed.
"The weather is always a challenge," Maggie Green, from the Kansas City Public Works Department, told Fox4KC.
"I know they got a lot done this week with the good weather. Last week they patched almost 2000 potholes. Anytime it's pouring down rain it's difficult to patch but as long as we have good weather, crews are out there working on that list."
She added that 10,000 of the 15,000 reported potholes had already been fixed.
Sereno's three-month-old pothole was repaired earlier this month, just a few days after the birthday party.
