Theresa Mary Zielinski

Dear Family and Friends,

It is with heavy hearts that we share the news of the passing of Theresa Zielinski, who died peacefully at her home in Las Vegas on February 14, 2026.

It was impossible to know Theresa and not to love her; her happiness and warmth made her the center of many joyful occasions. Throughout her life, she enjoyed a long and successful career in dentistry and also dedicated her time to various volunteer efforts. She was also an avid reader and loved learning.

Theresa is survived by her loving and devoted husband John; they met in their teens and recently celebrated 63 happy years of marriage. She is also survived by her daughter and son-in-law, Shawna and Jonathan Haase, her brother Anthony Giammarco and her sisters Leonora Anderson and Jill Ehrenfeld. She shared lifetime bonds with all of them as well as with her many other family members and friends. Theresa was predeceased by her parents, Carlo and Mafelda Giammarco and by her younger daughter, Tracy Zielinski.

She is deeply missed by all who knew her.
