Mary Jo Suminski

1953  –  2026

Née Halmo

Born to eternal life Sunday, November 8, 2026, at the age of 73. Beloved wife of 44 years to Raymond J. Suminski. Cherished mother of Eric (Beth) Suminski. Loving grandmother of Austin, Annabelle, Evan, and Elena Suminski. Dear sister of Judith (Jack) Sullivan, the late Stephen (Paula) Halmo, Michael (Moreen) Halmo, and Bill Halmo. Further survived by many loving nieces, nephews, relatives, and friends. Preceded in death by her mother, Madeline “Maggie” Halmo (née Miller).

Mary Jo — “MJ” — was best known for her unique ability to bring laughter and joy to everyone around her. When she walked into a room, the room got brighter and the soundtrack just a bit louder (figuratively and literally — she loved her music!). Strangers became instant friends, and new acquaintances grew into lasting relationships. That radiance carried through to her professional life, where she earned her master’s degree from the Milwaukee School of Engineering (MSOE) while also serving for over 20 years as an instructor in its School of Business. Along the way, she touched the lives of countless colleagues and students with her generous spirit. What may have been considered “normal” by those closest to her was truly a special quality, never to be taken for granted (yet, at times, we may have). She lived in service to those around her — often subtly and in her own way, but in service nonetheless.

There is no doubt that every life Mary Jo touched — whether as a wife, mother, aunt, grandmother, best friend, coworker, or simply a casual acquaintance — was indeed blessed by her presence.
