Plishka comes from Old Forge, Pennsylvania, and Paterson, New Jersey; his parents were American-born children of Ukrainian immigrants. He attended Eastside High School and studied at Montclair State College and with Armen Boyajian, and made his operatic debut with the Paterson Lyric Opera, in 1961. Plishka made his formal debut with the Metropolitan Opera as the Monk in La Gioconda, in 1967. He became one of the company's leading basses, and has appeared in many other theatres, including the Teatro alla Scala and the New York City Opera. He retired from the Metropolitan Opera after playing the Sacristan in Tosca, on the Saturday broadcast on January 28, 2012. He had performed at the Metropolitan Opera for forty-five years and in 1,642 performances, placing him at number ten on their official list of most-frequent performers, which dates back to the company's inception in 1883. There was a special tribute after Act I on stage, and on the air during the intermission. In 2016 he was invited back to the Metropolitan Opera for five post-retirement performances as Benoît and Alcindoro in La bohème in April and May of that year, and 10 more in November, December, and January in the 2016/2017 season. At La Scala, the bass appeared in La damnation de Faust, Boris Godunov, Anna Bolena, I lombardi, Nabucco, Turandot, and I Capuleti e i Montecchi. His last performance with the company was in 1992, in the Verdi Requiem. He is a National Patron of Delta Omicron, an international professional music fraternity. Paul Plishka's artistry was recognized in 1992 when he received the Pennsylvania Governor's Award for Excellence in the Arts and when, several years earlier, he was inducted into the Hall of Fame for Great American Opera Singers in a celebration at the Academy of Vocal Arts in Philadelphia. However, Plishka's international artistic successes have been dampened by a life filled with personal tragedies. In 1984, Plishka's younger brother, Dr Peter Plishka, was found dead in his Bronx apartment with a self-inflicted stab wound. At the time, Dr Plishka, 33, was chief of children's services at the state-run Children's Psychiatric Center. In 1991, Plishka's son Jeffrey was accused of the murder and rape of Laura Ronning, a crime of which he was eventually acquitted in 2010. In 2004, Plishka's first wife, Judith Ann Plishka, Jeffrey's mother, died, according to an obituary in The New York Times. Plishka is currently married to Sharon Thomas, a former resident stage director at the Met. Another of Plishka's sons, Paul, Jr, also died, according to Pastor Protopresbyter Nestor Kowal of St MichaelUkrainian Orthodox Church in Scranton, Pennsylvania. Plishka has a third son, Nicolai.
