Thymios Prokopios Lambrou

Dr. Thymios P. Lambrou passed away peacefully on October 26th 2025 in St. Louis, Missouri, at the age of 86, one month shy of his 87th birthday.

He was born in 1938 on the Greek island of Evia, the son of Prokopios and Kalliopi Lambrou. His early life was shaped by the hardships of World War II and growing up in a large, close family with eight siblings. Those formative years instilled in him resilience, empathy, and a lifelong devotion to helping others.

After serving in the Greek military, he pursued his dream of becoming a physician. During his medical studies he met his first wife, Betsy. They married, came to the United States, and built a life together while he completed medical training in Los Angeles, Yonkers, Youngstown, and Houston. He chose the field of oncology and completed his final residency year at MD Anderson in Houston, Texas.

In 1982, Dr. Lambrou moved his family to Poplar Bluff, Missouri, where he began his career as a caring and dedicated oncologist. He later went into private practice, serving patients across the rural communities of southeast Missouri including Doniphan, New Madrid, Sikeston, Chaffee, and Scott City. He approached medicine as a calling rather than a business. Known for taking the time to connect with his patients, listening without judgment, and treating every individual with dignity, he often quietly gave money for those in need. His generosity was steady, sincere, and unquestioning.

In 1994 he married his second wife, Rebecca, with whom he shared great love and a blended family. Their years together were filled with joy, devotion, and deep companionship until her passing from cancer in 2003.

Dr. Lambrou was a man driven by curiosity and an unquenchable desire to understand the world. He was passionate about philosophy, poetry, social science, and economics. He loved to learn, to debate ideas big and small, and to share spirited conversations on everything from religion to physics to the nature of consciousness. He delighted in Greek poetry and often translated verses by Yiannis Ritsos simply for the pleasure of it.

He was also known for his humor and warmth. His Greek accent often produced unintentionally memorable phrases that brought laughter to friends, family, and patients alike. He loved to tease gently, charm warmly, and make others smile. He was playful and affectionate with his children, and always ready with a story or a joke to see people smile.

Above all, he lived with compassion. He never measured success in wealth or status, but in kindness, service, and intellectual fulfillment.

He is survived by his sons Tassos and Nicholas; his step-children Karrie Clark and her husband Rick, Kevin McCallum, and Michael Kayle McCallum; his grandchildren Joseph McCallum, Kyle French, Kevin Clark, Evelyn Clark, and Carl Clark; his brother Takis Lambrou; and many nieces, nephews, relatives, and friends around the world. He was preceded in death by his parents and seven other siblings.

His legacy endures in the many lives he touched through medicine, friendship, and sheer generosity of spirit.

A memorial service will be held on Sunday, April 26th from 11:30am to 3pm at the Signal Event Center in Chaffee, MO.

In lieu of flowers, the family encourages supporting the American Cancer Society, Direct Relief, or by helping someone in need directly, as he often did.
