Donald P. “Donnie” Miller

Donald "Donnie" Miller, 59, of Coraopolis, PA, passed away unexpectedly on March 12, 2025. Born on February 10, 1966, in Pittsburgh, PA, to Don and Margaret (Donagan) Miller, Donnie lived a life full of passion, adventure, and love for his family.

Donnie was the devoted husband of Margaret "Joni" Heifner-Miller and a proud father to their children, Elizabeth Heifner, Royce Miller, and Pierce Miller. He was a beloved brother to Tracy Sommer (husband Dave) and their children Marshall, Benjamin, Nicholas, and Jackson, as well as Lara Walter (husband Bob) and their children Chelsea and Chase. His parents, Don and Margaret, also survive him.

A faithful Catholic, Donnie graduated from Indiana University of Pennsylvania (IUP) with a business degree. He began working at Miller Plastics in 1988, proudly joining his father in the family business. Over time, he became the president and owner, leading the company for 25 years. With his vision and dedication, Donnie modernized Miller Plastics, transforming it into the industry leader it is today, leaving a lasting legacy in both the business and the community.

Donnie was an avid outdoorsman and thrill-seeker, with a love for boating, motorcycles, cars, jet skiing, camping, and swimming. A lifeguard in high school, he cherished the ocean and traveling with his family. Known for his vibrant spirit, he lived by his catchphrase, "Drive fast, take chances," embodying his zest for life.
