Dennis Patrick Dalton

July 14, 1946 – June 2, 2026

Dennis P. Dalton spent his life helping people. As a soldier, police officer, mentor, husband, father, grandfather, son, brother, and friend, he was happiest when he was taking care of others. He passed away on June 2, 2026, at the age of 79.

Born in Portland, Oregon, on July 14, 1946, Dennis was the eldest of three children born to Larry and Marion Dalton and was later joined by his younger sister, Donna, and younger brother, Doug. He attended Central Catholic High School before graduating from Madison High School in 1964.

In June 1966, Dennis enlisted in the United States Army. After completing basic training at Fort Gordon, Georgia, he served as a Sergeant in the Military Police while stationed in Munich, Germany, returning home in June 1969. He continued his education by earning a bachelor’s degree in Criminal Justice from Portland State University and later a master’s degree in Education from the University of Portland.

Dennis devoted more than 30 years to law enforcement and public service. He began his career with the Oregon State Police in St. Helens before serving with the School Police and the Transit Police. He ultimately joined the Portland Police Bureau, where he proudly served until his retirement in 1997. Among his proudest accomplishments was training young officers, many of whom went on to distinguished careers of their own. Dennis took great pride in being a police officer and believed the badge carried both responsibility and privilege. He never forgot that behind every call was a person who needed help.

While serving with the Oregon State Police in St. Helens, Dennis met Kathleen (“Kathy”) in February 1973. They were married on July 21, 1973, and shared more than 52 wonderful years together.

Nothing brought Dennis greater joy than the people he loved. He was most proud of his children and the lives they built. They, in turn, gave him his greatest treasures—his grandchildren. He delighted in celebrating their accomplishments, sharing time together, and making memories that would become cherished family traditions. In his own words, his greatest peace came when his family was together.

Dennis will be remembered for his booming laugh, playful sense of humor, and appreciation for life’s simple pleasures. He loved the music of the 1950s and 1960s, never missed his favorite Thanksgiving episode of Cheers, and believed that a bowl of ice cream was always better with a generous drizzle of salted caramel. He leaves behind countless stories, traditions, and inside jokes that will continue to bring laughter to his family for generations to come.

Dennis is survived by his beloved wife of more than 52 years, Kathleen (“Kathy”) Dalton; his daughter, Kristen Mawdsley and her husband, Steve, and their children, Joey and his wife, Sydney, of Dassel, Minnesota, Faith, and Luke; his son, Bennett Dalton and his wife, Dr. Erin Dalton, and their children, Elaine and Roger; his daughter, Merritt Sansom and her husband, Clint, and their daughters, Charlotte and Violet; and his son, Brett Dalton and his wife, Lauren, and their children, Dean and Holly. He is also survived by his sister, Donna; his brother, Doug; and many beloved nieces, nephews, great-nieces, and great-nephews.

He was preceded in death by his parents, Larry and Marion Dalton.

Dennis considered himself a fortunate man. Those who knew and loved him know just how fortunate they were to have shared in his life.
