On July 22, 2025, Zachary posted on Instagram:“Today would have been my dad’s 74th birthday. Every year, this season arrives with gravity. In just sixty days, we pass through Father’s Day, his birthday, and the anniversary of his death.”He continued:“For me, grief isn’t linear, It loops and echoes. It softens, then crescendos. But alongside it lives a legacy, the kind built not from fame or recognition, but from generosity and relentless kindness.”The post came during what Zachary described as a “tender and complicated stretch of time,” encompassing Father's Day, his dad's birthday, and the anniversary of his death.A postmortem examination showed that Robin had an untreated Lewy body dementia, a progressive disease whose symptoms include depression, anxiety, paranoia, and hallucinations, along with disconnection of cognitive abilities.Zachary also shared a more personal dedication to his father:“Lived to make people feel seen. He gave permission to feel deeply and to laugh through the pain. In his absence, that mission continues.”He concluded his Instagram message with reflections on how best to honor those no longer with us, saying that he believes living by “the values they stood for,” leading “with service and compassion,” helping others “when they’re down," and finding “paths of light, even in the dark corners.”Offering assurance to anyone still grieving, Zachary added:“You’re not alone. You are part of a passage of love and connection that never really ends.”He also recalled how Robin was worried when he was mistakenly diagnosed with Parkinson's disease, a detail Zachary shared in a 2021 conversation with The Genius Life podcast.
