Katherine Mary Pfeiffer (nee Otto), born April 22, 1954 passed peacefully on June 24, 2023.

She was preceded in death by her parents Wilbert and Mary Otto and the love of her life Richard Pfeiffer. A beloved wife and best friend to Dick (20 years), loving mother to Stephanie and Eric, big sister to William (Michele) Otto, Barbara (Joseph) Romanowski, and Judith (Michael) Brockel, caring aunt to her niece and nephews, and loving grandma to her grand-dog, TJ.

Kathy carried her spirit with her everywhere she went. She loved her family, being the life of the party, making others laugh, the Packers, and most of all, Blake Shelton. To know Kathy was to love her, her presence in the lives she touched was a profound gift. Her spirit will live on in those she graced.

Kathy's long and powerful fight could not have been battled without Dr. Patel, and the staff of Reiman Cancer Center, and the wonderful care they provided to her. Kathy's loved ones thank them immensely.

In lieu of flowers, the family requests that memorials may be made to Leukemia and Lymphoma Society https://www.lls.org/
