Dora Adelaide Koeller passed away peacefully in her sleep on February 23, 2026.

Dora was a devoted Christian, and her faith guided her throughout her life. Her family finds comfort in knowing she is now in Heaven, free from pain, and at peace.

She was the beloved wife of Herbert Koeller, who passed away on January 22, 2015, and a loving mother to Danielle Serblowski (Jason) and Tyler Koeller (Elena).

Dora was a proud and cherished grandmother to Julian Serblowski, Jack Serblowski, and Grace Koeller. Her grandchildren brought her immense joy.

She was also a dear sister to José Carlos Pimentel (Filomena), Olga Baltazar (José), and Natalia Mitchell (Tim). Dora was a loving aunt to her nieces and nephews Sandra, Linda, Mark, Lisa, Andrew, and Lindsay.

Dora will be deeply missed by her family and friends. Her love, faith, and gentle spirit will remain in the hearts of all who knew her.
