James Harrison Miller Jr.

On September 27, 2026 James Harrison Miller, Jr passed away at the age of 97. Jim was known to many in the Atascadero and San Luis Obispo County communities, and throughout the greater California farming areas. Beloved by many, Jim collected a number of colorful nicknames over his long and storied life, including “Sugar Beet”, “Diamond Jim” and “Mr. Miller (heavy on the mister).” Yet of all the names he was called, the ones he cherished most were husband, Dad, Grandpa, Uncle, Jimmy, pardner, and friend.

In the way of legends, Jim created a life all his own, rich with adventure and marked by hard work, resilience, and an unwavering sense of who he was. Born July 5, 1929, to Anna Huffmyer and James H. Miller in Aliquippa, Pennsylvania, Jim spent his early years on a farm in the heart of coal and steel country. He struck off on his own and worked as a groom on a traveling racehorse circuit. By the age of 14, he had visited every state east of the Mississippi. After WW2, he followed his mother and sisters when they relocated to southern California. In 1947, Jim enlisted in the U.S. Army and served overseas during the Korean War. Following his service, he recuperated at the VA hospital in Sylmar. During that time, he often travelled to Oceanside to visit his mother, where fate introduced him to the love of his life, Donna Barlow. Determined to win her heart, Jim would famously sneak out of the hospital to court his future bride. The two met in 1950 and began a love story that would span a lifetime.

Donna and Jim married in 1951 and shared 72 years of love and life. They began their life together by living on campus in married student housing at Cal Poly. In the summers, Jim would work on a grain ranch on the Carrizo Plain and ran the Farm Bureau grain cleaner.

At a Cal Poly rodeo, he met his greatest friend, Jack Rogers, who taught him western riding and introduced him to the cowboy way of life. Donna’s grandfather, an ol’ timer of the Sierra Nevada, further shaped Jim’s love of the West by taking the young couple into the high country each summer and teaching him to pack mules. Those experiences sparked a lifelong passion. Jim continued riding and packing well into his later years, often saying he never felt as good as he did in the saddle.

In 1963, Jim and Donna purchased their home in Atascadero, where they would spend the next 60 years building a life, raising a family, and welcoming generations of friends and loved ones. Jim worked for the Union Sugar & Holly Sugar companies as a fieldman and company representative, traveling throughout California’s farmland and developing lasting relationships with growers and farming communities, and retired in 1993.

Whether working with farmers, riding the backcountry, competing in rodeos, or playing a game of Pidro, Jim embodied the values of the American West. He passed on his love of horses, the outdoors, self-reliance, and friendship to his children, grandchildren, and the many others fortunate enough to know him.

A firm believer in giving back, Jim was an active and familiar presence throughout the community he loved. He was a charter member of the Paso Robles Elks, served for many years on the board of the California High School Rodeo Association District 7, and was a past president of the Atascadero Trail Riders. He was also a Freemason and worked as ground support during wildfire season. Whatever the need, Jim was the kind of person who showed up.

For many years, Jim and his family grew and sold Christmas trees through Miller's Holiday Pines on Ramona Road, creating holiday memories for generations of local families. Through his service, mentorship, friendship, and example, Jim helped strengthen the community he called home.

Jim and Donna lovingly raised three children, while also welcoming many others into their lives who came to think of Jim as a second father. He is survived by his sons, Charlie (Lynette) Miller and Steve (Bridget) Miller, and reunites in eternal peace with his daughter, Ellen Miller, who preceded him in death. He dearly loved, and was deeply loved by, his three sisters, Sue Verosko, Donna Mae Mundell, and Mikellee Pesenti, as well as their husbands, children, and grandchildren.

To his grandchildren, Jim was more than a grandfather. He was a teacher, mentor, cheerleader, and trusted companion. Whether chalking a ball field, driving hundreds of miles for a rodeo, hauling livestock to the fair, or sharing the finer points of knot tying and horsemanship, he found countless ways to show his love. His seven grandchildren, Jessica Lancaster, JD Miller, Alissa Miller, Marlee Quaintance, Dillon Miller, Emily Miller, and Ana Miller, and his twelve great-grandchildren will forever carry with them the lessons he taught, the stories he shared, and the example he lived every day.

An avid reader and lifelong problem-solver, Jim found joy in gardening, leatherworking, and fishing. He was tough as nails and worked hard his entire life. His booming laugh, gift for storytelling, and capacity to love deeply left a lasting impression on everyone who knew him. Beneath his rugged exterior was a patient, kind, and generous soul.

Jim's life and legacy will be honored by the Millers, his extended family, and the many friends who became family at a Celebration of Life, with details to be announced.
