Dean Spiro Dussias, one of Illinois’s most prominent family law attorneys and a founding partner of Dussias Wittenberg Koenigsberger LLP, passed away on June 14, 2026. He was 61 years old.
The news was announced by his law firm and by Saints Constantine and Helen Greek Orthodox Church, where Dussias was a member of the congregation.
His firm described him as someone who was simply “one of one,” a phrase that speaks to how irreplaceable he was to everyone who knew him.
Beyond the courtroom and the conference room, those who crossed paths with him consistently point to his warmth and his uncanny ability to make every person feel genuinely valued and seen.
Dussias built a career over decades that earned him the respect of peers across the country. He served as a past President of the American Academy of Matrimonial Lawyers, a distinction that places him among the most accomplished practitioners in his field nationally.
As a founding principal of DWK LLP, he helped shape a firm built on integrity and excellence in family law. His professional legacy is substantial, but colleagues and friends are quick to note that his character far outweighed even his considerable accomplishments.
A Man of Faith, Family, and Extraordinary Generosity
Those who knew Dean Dussias personally describe a man whose faith was central to everything he did. His membership at Saints Constantine and Helen Greek Orthodox Church was not peripheral to his life but woven into the fabric of who he was.
The church announced his passing with the traditional Orthodox expression of grief and hope, noting his death with the words “falling asleep,” a phrase that reflects the belief in resurrection at the heart of his faith.
He leaves behind his wife, Maria, and his children, Stephanie, Sammy, and Arthur. His family was the foundation he returned to, the reason behind the long hours and the hard work.
Friends from the Greek Orthodox community have flooded social media with the words “Memory Eternal,” the traditional prayer offered for the departed in the Orthodox tradition, reflecting how deeply he touched lives beyond his immediate circle.
Lifelong friends, including his koumparoi, have spoken publicly about being heartbroken at his passing. In the Greek community, the bond of a koumparo, a godparent or wedding sponsor, carries enormous weight.
That multiple people came forward using that word to describe their relationship with Dean says everything about the kind of friend he was.

Dean Spiro Dussias was 61 years old. He leaves behind a family who adored him, a firm that will carry his name forward, and a community that will not forget him.
