Mark Allen Overstreet of Beech Grove, IN was found dead on April 23, 2025. He was born on November 26, 1957, in Indianapolis, IN. He was preceded in death by his parents Frank and Martha Overstreet. He is survived by his ex-wife Diane Overstreet (m.1982-2020); sister Elizabeth “Sissy” Hamilton; children Derek (Cynthia), Kari and Kristen Overstreet, and granddaughters Lucy and Cora Overstreet. In his early years, Mark was a scholar and an athlete, graduating near the top of his Lawrence Central High School class in 1976 and playing safety on the football team including an undefeated season in 1974. He went on to Purdue University where he joined Sigma Alpha Epsilon and earned a bachelor’s degree in mechanical engineering, followed by an MBA from Seattle University. He spent nearly 30 years as an aerospace engineer, working for Boeing, Allison Gas Turbine, Rolls-Royce, GE, and Hamilton Sundstrand. Mark was a generous provider for his family. At various times he commuted from Indianapolis to Cincinnati, OH and Rockford, IL, for up to a week at a time. He was extremely supportive and proud of all his children for all their achievements, big and small. As Mark’s father (a long-time bluegrass musician and writer himself) fell ill in the early 2000s, Mark took an interest in bluegrass, picking up the mandolin and starting a band (the Starlight Ramblers) with friends Jim Blazek and Roger Bough, which Derek quickly joined. Mark sang lead on nearly every song. The band’s ratio of setlists made to paying gigs was greater than 100 to 1, but the band was a roaring success as measured by the memories made over nearly 25 years, and Mark was the beating heart of it.
In his later years, Mark struggled with his mental health and drug addiction. Despite great internal challenges, he established a strong relationship with his granddaughter Lucy through regular video calls and a few special visits. Mark made many lifelong friends in nearly every phase of his life. Mark loved the Grateful Dead, the Bean Blossom Bluegrass Festival, the Purdue Boilermakers, the Indy 500, gardening (especially roses like his mother), and, to the bemusement of many, his Oldsmobile woody wagon, which he refused to give up on until smoke came out of the air vents, the muffler had fallen off, and the window tint in the back was thoroughly ruined. His family will forever remember him sitting at the front room table, where he assiduously revised the family budget multiple times a week with his trusty leather briefcase popped open in the seat next to him.
A gathering to celebrate Mark’s life will be hosted this summer by Diane Overstreet, currently planned for Sunday, June 22.
