Ronald John Riopel, 89, of Three Rivers, passed away Monday, November 28, 2022 at home, surrounded by his loving family. He was born July 14, 1933 in Chicago, Ill., the son of John August and Anna Louise (Ebert) Riopel. Ron earned his bachelor of science at Western Michigan University: a triple major in physics, chemistry and mathematics, and a minor in history. He followed that with a master's degree in electrical engineering at Notre Dame. He went on to train generations of students as a teacher for 26 years at Three Rivers High School, and for 23 years at Kalamazoo Valley Community College. In Three Rivers, he was chair of the math and science departments and developed the honors math program and the original advanced placement program for calculus and chemistry. He was very involved in National Honor Society and various other activities. Ron was also very active in Three Rivers Little League for 20 years and attended Immaculate Conception Catholic Church. He obtained the rank of 1st class petty officer in the United States Navy. He served in the Korean War primarily on the DMS Ellyson as a boiler-tender, Sharpshooter and 40mm gunner. Ron married Anne Brady on August 7, 1976 at Immaculate Conception Catholic Church. They enjoyed traveling as a family with son John and in later years especially enjoyed visiting World War II and other military memorials. Ron enjoyed creating displays that honored American military heroes. He had special pleasure in sharing his knowledge and stories with everyone, and particularly with his two grandchildren. He shared with them his love of math and science and how to make aunt Sophie's cookies. Remaining to cherish Ron's memory are his wife, Anne Riopel; son, John (Jen) Riopel; grandchildren, Riley and Jaxon; many beloved brothers and sisters-in-law, nieces and nephews, great-nieces and -nephews, and many close friends. He was preceded in death by sister Dolores (and Roman) Skinner along with his parents.
