Dennis Michael Flinn, 72, of Wentzville, Missouri died on December 22, 2021. Dennis was born in St. Louis, Missouri but his father was in the military and they lived in various places stateside and overseas. He graduated from Knob Noster High School in Missouri and attended the University of Missouri, St. Louis where he received a Bachelor of Science Degree in Administration of Justice and  Master's Degree in City Management.

He transferred to the County Headquarters in Clayton where he began a career as a data base analyst. Dennis left the Department and continued with a career as an analyst and consultant for a number of companies throughout the years.

Dennis was most proud of his family and faith life. He married Annette Barczykowski on June 17, 1972 and their two sons came a few years after that. He was a huge proponent of education and made sure the boys always had access to the best schools possible and pushed them to give their very best in whatever they were pursuing. Late in life, Dennis was pleased to welcome two wonderful daughters-in-law and six grandchildren.

Dennis was active in his community as a member of the Knights of Columbus and the ACTS groups at St. Patrick Church in Wentzville.
