Christopher Oestreich

Christopher “Sean” Oestreich, 59, of Springfield, was born on July 3, 1966, in St. Louis, and grew up in nearby Kirkwood. Sean passed away peacefully on Aug. 24, 2025, at his home on Table Rock Lake. This was his happy place, and he got to spend his final day on the water with his wife and friends.
He lived a life filled with love for the outdoors. Whether it was fishing, hunting, scuba diving, boating, swimming, grilling, or even working in the yard, he found joy and purpose in being outside and sharing those moments with others. He also deeply valued friendship and connection. He was always the life of the party, quick with a laugh, and happiest when surrounded by people he loved. His group of childhood friends has kept their bond strong, getting together every year for 41 consecutive years.
Professionally, he was hardworking and dedicated to providing for his family. He began his career in insurance, transitioned into property restoration, and ultimately built and grew an environmental air quality business into the successful company it is today. His interactions have made lasting impressions on so many people through his work.
He was preceded in death by his infant daughter, Carly, who passed away in 1995 at just six weeks old.
He is survived by his loving wife of 33 years, Laura Oestreich; his children, Ryan Oestreich and his wife Hayle, and Jane Smith and her husband Sawyer; and his two granddaughters, Ella and Anna, both of whom he was able to meet and spend cherished time with. He is also survived by his mother, Virginia Garesché, and his sister, Shannon Oestreich Thomas. Father William Oestreich. In laws, Don and Teresa Sinclair.
He will be remembered for his adventurous spirit, his humor, his love of friendship, his ability to make others feel welcome, and his hugs.
In lieu of flowers, the family asks that donations be made in Sean’s memory to St. Jude Children’s Research Hospital. We believe this is what he would have wanted as a kind and generous son, father, husband, brother, and friend.
