On January 12, 2026, at the conclusion of the Divine Mercy Chaplet, led by Sister Elizabeth, SSM, Beverly J. Trehey, took her last breath at 3:00a.m. with her loving husband and children by her side.

Beverly was born on October 26, 1949, in Kansas City, Kansas, to Edward Carl Milberger and Naomi Duncan Milberger. Her childhood was filled with love and joy, especially during time spent with her many cousins. She discovered her love for dance and music at Miss Dorthea’s studio. Beverly enjoyed dancing with her friends and felt such pride whenever they would perform in the beautiful custom costumes handmade by her mother.
Beverly graduated from Wyandotte High School in 1967 where many cherished, lifelong friendships were formed. Following her graduation, she attended the University of Kansas and KCKCC, where she developed an interest in computer science. This led to a successful career in data processing.
On August 17, 1968, Beverly married the love of her life, Daniel J. Trehey. Together, they raised three children, whom they considered their greatest achievement. The family grew up with The Cathedral of St Peter the Apostle as their backdrop. Beverly and Dan took pride in giving their children a Catholic education and celebrating all their childhood sacraments at the Cathedral. They prayed that this strong foundation would sustain their children throughout life's journey.
Beverly dedicated herself to being a stay-at-home mom until her children began school. She provided her children with a well-rounded upbringing by focusing on education, friendship building, and physical activities, while allowing them to simply enjoy being kids. Beverly played an active role in every part of their lives—serving as a room parent, driving neighborhood carpools, volunteering at church, coordinating activities, organizing memorable birthday and slumber parties, or simply relaxing on the deck watching childhood memories being made. Beverly valued the relationships she formed with other like-minded mothers as they raised their children together.
Once her children began attending school full-time, she launched a career at Boilermakers National Funds. Her passion for technology made working in the computer field especially rewarding, and she felt fortunate to build her career in that area. While she enjoyed the work itself, it was the colleagues who truly made the experience meaningful. After eighteen years of dedicated service, she retired from her role as Data Processing Supervisor.
The highlight of every summer was the annual trip to Table Rock Lake - the excitement leading up to it was as fun as the trip itself. When the family was younger, these vacations often lasted just a couple of days, but over time, stays grew longer. A cherished memory for Beverly and Dan was celebrating their 50th wedding anniversary by bringing the entire family to Table Rock Lake for an extended weekend. They revisited the past by reliving their children's childhood experiences and enjoying the lake through their grandsons’ eyes – everyone together, soaking in every moment.
As empty nesters, Beverly and Dan kept up their regular Table Rock Lake and Branson visits, turning them into monthly excursions. Casinos were a guilty pleasure; they never missed an opportunity to frequent one or two. Downstream Casino was their favorite - happily always having a junket on the books. They sure enjoyed this phase of life together. Sadly, it was cut short due to illness.
Beverly was predeceased by her parents, her brother Edward Carl Milberger II, and her sister Diane Voiles. She is mourned by her husband, Daniel J. Trehey; her daughter, Sheri Lynn Seeman (Albert); her sons, Daniel J. Trehey IV (Kathy) and Michael Edward Trehey; and her grandsons: David J. Seeman, John Victor Seeman, Daniel J. Trehey V, and Nicholas M. Trehey. Beverly is also survived by her nieces, Lisa Glander, Mary Devosha, and Ashley Milberger, as well as her nephew, Edward Carl Milberger III.
Our family wishes to express sincere appreciation to these remarkable individuals: the Sisters, Servants of Mary, Mother Ema, Sister Elizabeth, Father Peter Jaramillo, Father Richard McDonald, Bridget Burns Vani, Sarah Kappelmann, Beverly Starks, and Therese Horvat. We are deeply grateful to each of you for guiding our mother on her final journey to Heaven.
