Dennis was born on March 27, 1948, in Gridley, CA, to Michael James Hafferty, an immigrant from Ireland, and Jessie Nealon Hafferty of Marysville, CA.

Dennis spent his childhood on his parents' ranch in the Manzanita area and helped out at the family's variety store in Gridley, CA.

His upbringing instilled in him a deep appreciation for family, friendships, and hard work, values that defined him throughout his life.

He was a proud graduate of Gridley High School, where he played on the basketball team, served as editor of the yearbook, and made lifelong friends.

After high school, Dennis began working at Sunsweet in Yuba City, CA. He met the love of his life, Judith "Judy" Anne Johnson, during the time that he was employed at Sunsweet.

On October 21, 1972, he married his beautiful bride, and in doing so, took on two children, treating and thinking of them as his own. Together, Dennis and Judy built a life full of laughter, travel, and deep devotion to one another.

Dennis went on to work for Recology, where he dedicated over 40 years of service before retiring. Known for his patience, reliability, and strong work ethic, Dennis made a lasting impact on his colleagues and the community he served.

During his leisure time, Dennis enjoyed many diverse activities. He loved fishing and hunting with his close circle of friends and cherished trips that included poker games, laughter, and outdoor adventures.

He was an avid bowler and participated in numerous leagues and teams throughout the years. He was also active in the Fly-Fishing Club and proudly served as president of the Yuba Buttes RV Group alongside his wife Judy.

Dennis loved taking his RV on campouts with the group, spending time in nature and enjoying the open road. He and Judy were also members of the Gridley Dance Club, where they shared many joyful evenings on the dance floor.

Since 1979, Dennis was a dedicated and well-loved member of the Yuba City Moose Lodge, where he enjoyed spending time with fellow members and dancing with his beloved wife.

Dennis was a lifelong sports enthusiast and an avid supporter of the San Francisco 49ers, San Francisco Giants, and Sacramento Kings.

He took great joy in following his favorite teams and never missed a big game. During the glory days of the 49ers, Dennis especially loved hosting Super Bowl parties at home, where he and Judy welcomed friends and family to share in the excitement, food, and fun.

Dennis lived a full and generous life. He was a patient and caring man, always willing to lend a hand.
