Ronan Michael Ciesinski, aged 17, of Piedmont, OK, died unexpectedly at home on December 17, 2021. The beloved son of Annette and Paul Ciesinski, he was born in Hartford, CT, and lived with his family in East Hampton until they moved to Piedmont in 2014.Ronan was homeschooled, and a high school junior. He was a terrific drummer. All kinds of music interested him, especially jazz and Gregorian chant. He played the cello for the Homeschool Band and Strings as well as bass drum for the Homeschool Marching Band when they played for the Patriots Homeschool football team. He was self-taught on bass guitar. He ran cross-country for the Knights, played T-ball, and had worked at Braum's Ice Cream and Dairy Store in Oklahoma City. A member of Boy Scout Troop 331 at St. Monica's Church in Edmond, Ronan took pride in the fact that he was only 15 when he made Eagle Scout, while it took his brothers until age 16. His Eagle Scout project was building picnic benches for the St. Damien Church playground. Camping with the Scouts and his dad was at the top of the list of his all-time favorite things to do. He particularly enjoyed the camaraderie of hanging around the campfire in the evening with the other Scouts.Ronan liked to cook and bake and would try any food once. Sushi, broccoli, and pizza got a thumb's up, peas a thumbs down. He liked to watch 80's action movies, play video games, and drive the boys' Chevy Silverado. Ronan loved animals, especially rabbits, raised chickens, and enjoyed being outdoors watching wildlife with his best buddy Michael. Ronan was a parishioner at St. Damien Catholic Church, where he sang in the Schola and had been an altar server. When he lived in Connecticut, he was an altar server at St. Bridget of Kildare Catholic Church in Moodus.
