Thomas William Dietrich, 70, of Lake St. Louis, Missouri, passed away on November 13th. Born on December 20, 1954, in Clarksville, Missouri, Tom grew up along the Mississippi River and proudly graduated from Clopton High School in 1973.

Tom dedicated his early career to public service as Pike County Prosecuting Attorney, and later as a judge. He spent more than forty years as a corporate attorney with Peabody Energy in St. Louis yet never hesitated to offer his "pro-bono" help to anyone who needed it. His unwavering commitment to justice, integrity, and fairness shaped every part of his work and life.

A man of faith, Tom attended the Church of Christ and found joy in life's simple blessings and he currently was a member of River Oaks Church in Foristell, MO. He treasured time with his family-especially being goofy with his granddaughters and bantering with his brothers. Whether he was building projects with his children and brothers, spotting wildlife during numerous visits to Alaska, playing a practical joke on someone, or sharing wise advice wrapped in humor, Tom brought joy and laughter to everyone around him.

Tom is survived by his brothers, Terry, Jim, and Eddie Dietrich; his children, Joe Dietrich, Sara Platt, and Ashley Wood; four beloved granddaughters-Emma, Ava, Mayli, and Teagan; his wife, Joyce Dietrich; step-children Alisha, Angel, and Steven; and step granddaughter Emory Marie. He was preceded in death by his parents, Anton and Geneva Dietrich of Clarksville, Missouri.

He will be deeply missed and forever remembered for his humor, generosity, and unwavering love. His memorial service will be held on Friday, November 21st at Collier Funeral Home in Louisiana, Missouri with visitation from 1:00 p.m. until time of service at 2:00 p.m.

To honor his legacy, the family invites donations to the Greenwood Cemetery Fund, Clarksville Community Foundation, a cause close to his heart, and the Humane Society of Union, MO.

Dear Joy (Tom´s wife), Angel, and other family members of Tom,
My deepest condolences in the passing of Tom.
I was able to see him and talk to him at family events ( Ashley and Angels wedding reception will always be a highlight) and I enjoyed visiting with him and hearing about his latest adventures (building houses....his traveling and his family).
I´m so glad I was able to see him and talk to him a couple of months ago when I was at the home of Tom and Joy. I´ll always have fond memories of that visit.

My thoughts and prayers are with all you.

Papa Tom,
Remembering my stepfather with love and gratitude. In the few years we shared, he brought comfort, guidance, and a quiet strength into my life. I will always carry the memories of his kindness and the love he showed our family.
Rest in peace papa Tom, you deserve it.
Much Love & hugs,
Angel
