"Sam always had an infectious smile and a great sense of humor," Brister said, adding that Mosher loved to kid other people and be kidded as well.
"He was big-hearted, soft-hearted," Brister said, adding that though Mosher liked to come across as a tough guy, he was really a teddy bear inside.
"He always had time for others," Brister said. "He was always interested in his community."
Mosher considered a run for the El Centro City Council this fall but withdrew due to his health.
Mosher's son, Scott, said his father was full of life, energetic and always into something.
"He got the most out of life and when down in the dumps he had a way to uplift everybody," Scott Mosher said.
Scott Mosher said his father's fight against cancer never wavered and never got him down.
Memorial services will be at 10 a.m. Tuesday in Christ Community Church in El Centro for Mosher. Pastor Walter Colace will officiate.
Burial will be private.
