Brent Michael Cuillier was born at Our Lady of Lourdes in Pasco, WA on April 21, 1981 to Tom and Raelene Cuillier of Pasco, WA.

He graduated from Pasco High School in 1999. During high school his favorite class was welding. He could be seen in the early mornings hunting for pheasant with his German Shorthair, Kali. The summer after graduation he began his 20-year career in sales at Fastenal/Fasteners. Upon leaving Fastenal/Fasteners, he was recruited by International Belt in Pasco, where he worked for three years. He loved sales and helping the customers, many of them became life-long friends.

He was previously married twice, before reconnecting with his long-time friend, Laura Herrin. They were married on December 10, 2023 in the home he was raised in. They lived in Burbank, WA with their four dogs, until he passed away at the age of 44 years old.

Brent loved the outdoors, camping, hunting, going to the shooting range and fishing, which he said he "wanted to go rip some lips." He and Laura were ready to go at a moment's notice, grab their poles, worms and lures and head out, if his health permitted.

He also spent a lot of his time catching snakes and raising them, raising reptiles, ferrets, cockatiels, chickens, and several dogs, along the way. He loved animals.

He also loved working on cars and trucks and had several hot rods throughout the years.

He became ill about three years ago, but always tried to put on a brave face for everyone, so many didn't realize he was as sick as he was!

He passed away in his home in Burbank, on January 3, 2026 with Laura and their four dogs by his side.

Brent is proceeded in death by his grandparents, Raymond and Leona Massard, Edward and Margaret Cuillier, his aunt Elaine Needham, and his father Tom Cuillier. He is survived by his wife Laura (Herrin) Cuillier, his loving mother Raelene (Massard) Cuillier of Pasco, his sister Michelle Cuillier of Pasco, and his brother Danny Cuillier, his wife Heather, and their daughter Kendall Cuillier of Ashburn, Virginia. He is also survived by his nephew, Matthew Davis of Pasco and his niece, Tiffany Davis of Pasco. He also leaves behind several aunts, uncles, and cousins.
