Sidney Allen Mondin was born January 18, 1967, in Seguin, Texas, to Hazel Elaine Bode and Kenneth “Tiny” Wayne Mondin. Sidney was the fourth and final baby born of the family. He passed away on December 8, 2025 in Conroe, Texas, at the age of 58.
Sidney grew up as the baby of the family, naturally entertaining everyone around him with infectious energy and getting away with more than his older siblings. He whizzed through elementary school, spelling and writing better than other kids his age due to his love of reading… the dictionary. In middle school, he made his debut as the MC for the talent show, where he graced the audience with a performance of Rhinestone Cowboy, complete with a fringe shirt and sequin pants, hand-sewn by his mom and sister Alison. In high school, Sidney played football, won class favorite awards, and was the teacher’s favorite – likely because of his sweet-talking. He was everyone’s best friend and would give the shirt off his back to anyone in need of anything. From the age of 9, Sidney was an active member of the 4-H organization, showing several species of animals and participating on grass-judging and livestock-judging teams through high school. He was part of the Guadalupe County 4-H Team, placing third in the Livestock Judging Contest at the 1982 State 4-H Roundup at Texas A&M University, going on to the National Finals in Denver, Colorado.
After high school graduation, he moved to College Station, Texas and attended Texas A&M to obtain a bachelor’s degree in animal science, setting himself up for a career in agriculture. While pursuing his love of agriculture, he met the love of his life, Mona Hewitt. They married in June 1989, beginning a 36-year unforgettable adventure.
After college graduation in December 1989, Sidney and Mona moved to La Grange, Texas, where he worked as the Fayette County Extension Agent. In May of 1990, their first daughter, Lauren, was born. Two years later, in April of 1992, their second daughter, Kori, was born. In 1992, he was offered a position with Tyson Foods as a Production Manager in Holdenville, Oklahoma, where he and Mona built a life together, bought some land, remodeled a house, bought more land, built a red barn house from the ground up, and raised their two daughters.
In 2006, a change of career from agriculture to the oil and gas industry moved the family to Bloomfield, New Mexico, where he worked as a Branch Manager for PECOFacet. The next stop on the adventure began with a move to Spring, Texas, in 2008, where he worked as an Outside Sales Representative with Waco Filters; a Drilling Fluids Engineer with Halliburton; a District Sales Manager with Pall Filter Specialists; an Area Sales Manager with Parker Hannifin; and finally a Regional Manager with Filter Resources.
Sidney was a man with many talents and many hobbies. He loved his cows and had them so spoiled that he jokingly called them “his bunch of Democrats looking for a handout.” He decided that wine making would be fun, so he started experimenting with all kinds of fruity flavors, which then led him to plant a vineyard so he could use his very own grapes. He was extremely proud of his ponds, which he stocked with various species of fish – for the grandkids, of course. His morning ritual was to head to each pond and throw out handfuls of fish food so he could watch them boil to the top.
He sure spent a lot of time setting up game cameras and deer feeders for the amount of time he actually hunted. He loved the challenge of trapping hogs and had his game camera set up where he could see them from Spring and knew the exact moment to drop his trap’s wireless gate. It didn’t matter if it was 2:00 pm or 2:00 am – if he dropped the gate, he immediately would drive the hour and a half to the farm to load them up and haul them off.
The farm was his happy place. He spent his weekends fixing fences, burning brush piles, cooking breakfast and dinner on the blackstone, and perfectly toasting (never burning) marshmallows over a campfire, ending each day with a coke-n-Kraken…. BOOYAH! He was a builder, an electrician, a plumber, and an expert redneck DIY-er – able to figure out anything with enough time to just think it through with his “I can do anything” attitude. Sidney was every person’s handyman and every man’s best friend.
His latest adventure began in July 2025. He, along with Mona; his brother-in-law, Paul; and sister-in-law, Michelle, started a caulkless RV roof company called TuffTop RV Roof in Willis, TX. He helped build the business from the ground up, and his boisterous, friends-with-everyone, down-to-earth personality helped the business thrive more than expected from day one. He put his heart and soul into starting a business that would lead him into retirement, working only for himself and with his family.
