Biographical Text

John A. Cadigan, born July 7, 1942 in Portland, Maine, lived a life of honor and service to his country and his fellow man. Serving in the Navy from 1960 to 1966, John achieved the rank of E-4 IC3 and was a part of the naval crew on the USS Zellers (DD777) that defended our national security during the Cuban Blockade that protected our country in the time of President Kennedy.

Johns love for his community and civic duties in both California and Montana extended into the Jaycees, Chamber of Commerce, Rotary Club, and City Council. He also served as Mayor in Hercules, California and was given a lifetime membership to the Fairfield Lions Club.

In 1986 John met and married the love of his life, Toni. They married and shared the next 30 years living a full life that included a move to Montana in retirement, where they together built a picture perfect life at the Rockin’ JT Ranch, living on the high prairie in Fairfield, MT. They enjoyed gardening, raising horses and of course their faithful canine companions, Spud, JT and Paisley.

John will be missed. His sense of humor, his willingness to help his community, his honor, pride and love for life have been a constant source of strength for his entire family.

John’s wish is that you remember him in this way… as a kind soul with a belief in giving back and that he genuinely loved everyone.
