Mark William Sinnott

Mark W. Sinnott, 61, passed away unexpectedly November 12, 2023.  He was preceded in death by his parents Dr. John and Mary Ann Sinnott.  He is survived by siblings Kathleen, Paul, Maureen (Joe), Eileen (Murray) and Sean (Cathy).  Nephews and Nieces, Luke (Nichole), Cheyanne, John, Colin (Becca), Shannon, Jack and Sheamus.  Great Nephews Archer and Orrin and Great Niece, Olive.  Many friends and caring neighbors.  

Mark was a sports fanatic, but mostly for his beloved St. Louis Cardinals and Blues.  He had an amazing photographic memory for all things about teams, players, stats, specific plays, scores and more.  He was a character with a devilish laugh yet a sentimental soul with a big heart.  

Show your love of Mark by wearing all things Cardinals.
