Douglas Charles Isaac, 75, of Harmar Township, passed away Saturday, Sept. 26, 2020. While technically a resident of Harmar Township, Doug's name and legend was known far beyond borders. Doug wore many hats, literally and figuratively. He was known as an amazing father, grandfather, beloved companion, brother, teacher, coach, sports legend, musician and friend to an innumerable amount of people. His kindness resonated. Literally everyone knew him and loved him. Everyone. Douglas was born in Glendale, Calif., on Dec. 30, 1944. He attended Edinboro State College to become a beloved teacher, known mainly for his work in the Plum Borough School District. Known for his laser-accurate tennis skills, Doug played in tournaments all of his life. He was the tennis coach for many years at Plum Senior High School. Following retirement, Doug devoted time to music, tennis, racquetball and taking great care of his grandchildren. His impact on their development and sense of humor is incalculable. Local sports legend, musician, one-and-done marathon runner, science fan, caretaker, goofball and man about town, Douglas Isaac was a friend to all. Doug Isaac is survived by Kathy Fields, his partner of more than 20 years; children Brent and Samantha; grandchildren Madalyn, Riley, Moki and Domino; and his brother Donald, of New Kensington (wife Gloria, son Derrik). Doug is also somehow related to or associated with every Italian in Vandergrift and every Syrian in New Kensington. Arrangements are entrusted to RJ SLATER IV FUNERAL HOME & CREMATION SERVICE, 1000 Freeport Road, New Kensington, 724-335-0100, www.rjslater.com.

That's what he'd want.
