Robert L. Olinger, 75, of Mt. Lebanon, passed away on Monday, December 1, 2025. Loving husband of Doris Olinger (DiCenzo) for 47 years; proud father of Lesley Olinger and Scott Olinger; and affectionately known to friends and coworkers as “Bobby O”. Bob proudly served in the United State Marine Corps from 1968-1972. He was a member of the IATSE #3 Union. Bob worked all Pittsburgh venues ranging from opera to rock’n’roll. He served as Treasurer of the union for two years and as the President for two and a half decades. Upon his retirement, Bob was honored to be awarded the title of first President Emeritus for his leadership and contributions to Local #3. Bob was spirited and adventurous- he enjoyed fishing, target practice, competing in power lifting, and riding motorcycles. He had fond childhood memories of summer vacations in Stone Harbor, NJ which is a tradition he continued with his family.
