She joined the Civil Air Patrol in high school, worked at the Adrian, MI airport to pay for flight lessons. She soloed at sixteen and was a pilot at seventeen. She married fellow pilot Tomas Rivera-Serrano in 1949 and had five children. Despite having only a high school education, she did all the financial and tax work for their Gary, IN retail store. Helen was a loving mother, grandmother and wife.

Viola is survived by her five children, Thalia (Wilfred) Hernandez of Portage, Mirna (Michael) Dault of Knox, Thomas (Laura) Rivera, Jr. of Glenn Heights, TX, Virginia Rivera of Dunedin, FL and Maria Lisa Rivera of Hammond; two half-brothers John (Cherri) Duve of MI and William Duve of NY; three step siblings Elizabeth, John and Vera; six grandchildren, ten great grandchildren; one great-great grandchild; many nieces, nephews, cousins and dear friends around the country.
