Dr. Dennis B. Winthrop

Dr. Dennis Brian Winthrop, born April 21, 1950, in St. Louis, Missouri, passed away early in the morning of October 29, 2025, after a battle with dementia and recent seizures. He is missed by the family and friends who love him so dearly.

Born to Michael and Lois (Oberman) Winthrop, Dennis developed lifelong loves of history and baseball. Hours spent in history museums seemed like minutes and he was always ready to watch his beloved Cardinals, especially Stan Musial. He was a voracious reader, absorbing 4-5 books a month, with history being at the top of his list. Another love of his was sweets, appreciating cruising for the multiple dessert options and opportunities!

He studied dentistry at Washington University School of Dental Medicine, becoming a proud dentist loved by his patients for his friendly, social nature and care and concern for their dental health.

Dennis and Linda Finkelstein were married in 1974, enjoying 51 years together. They were regular cruisers, exploring ports throughout the Caribbean, but unfortunately missing out on a cruise to Alaska due to the tragic events of September 11.

Never having met a stranger, Dennis was well known for sitting outside and engaging his neighbors and passersby in any range of topics. His command of information served him well in games of Trivial Pursuit. He was also a dedicated member of United Hebrew Congregation, rarely missing a Shabbot service. He boasted that he had a reserved seat. Dennis loved celebrating the Jewish holidays, especially the ones that involved a good meal.

Preceded in death by his parents and son, Michael, Dennis leaves behind his wife Linda, daughter Carrie (David) Choate, grandchildren Ellison, Fielding, and Grayson Choate, sister Barbara (Phil) Forbes, sisters-in-law Martha (Phil) Caraballo and Rose (Randy) Marcus, niece Elizabeth Forbes, nephews Jonathan and Geoffrey Forbes, Aron and Alex Caraballo, and Eric and Brian Marcus, as well as friends and neighbors.

A memorial service is planned for November 14 at 12:30 PM at United Hebrew Congregation. May his memory forever be a blessing to all who know and love him.

In lieu of flowers, the family requests donations to the Michael & Lois Winthrop Religious School Fund at United Hebrew Congregation, 3788 Conway Road, St. Louis, Missouri 63141.
