Robert William Kaiser, 69, passed away unexpectedly on Sunday, April 27, 2025, at his home in Lebanon, Connecticut. Born on February 8, 1956, in Groton, he was the son of the late John and Judy (Ibrahim) Kaiser. Robert was a 1974 graduate of Bacon Academy in Colchester. A dedicated and hardworking man, he spent many years as the proud owner and operator of his own HVAC company, serving his community with skill and reliability. The oldest of four siblings, Robert grew up in Lebanon and remained close to his roots throughout his life. He had a deep love for his family and took great pride and joy in being an uncle, cherishing his nieces and nephews as if they were his own children. His passion for life extended to his interests, especially racecars, football, and motorcycles. Robert is survived by his loving sister, Marianne Kaiser of New Hampshire; his beloved nieces and nephews; and many other extended family members and friends whose lives he touched. In addition to his parents, he was predeceased by his siblings: James Kaiser and Jonnie Michelle Kaiser. Robert will be remembered for his generous spirit, quiet strength, and the love he gave freely to those around him. A celebration of Robert’s life will take place at a later date to be announced.
