Mary Therese Ronzio

Mary Therese Ronzio

(nee Hayes) "To be absent from the body is to be present with the Lord." On Wednesday, December 17, 2025, at the age of 67 years, Mary departed this Earth to meet Jesus face to face. Mary is survived by John "Jack" Ronzio, her husband, for 28 years. Loving mother of Claire Montenegro and Matt Yeager. Cherished grandmother of Giovanni and Leonardo Montenegro. Dear sister of Thomas (Mary) Hayes and Patricia (the late Richard) Keepman. Further survived by other family and friends. She is preceded in death by her parents, Jack and Mary Ruth Hayes.

Mary grew up in Beaver Dam, Wisconsin, went to high school in Waukesha, moved to Milwaukee and around 1982, after becoming a Christian, she moved next door to her parents with her children. Mary met Jack at Church in late 1991 when he had moved from Boston to Milwaukee and they were friends for two years until Jack moved back to Boston in 1993. In 1997, Jack was invited back to Milwaukee to a Patriots vs. Packers Superbowl party that Mary was attending, and at that party, Jack fell in love with Mary. That following Friday, Jack called Mary from Boston, proposed to her and two months later they were married. For 28 plus years, the Lord had kept their marriage vibrant and strong and he blessed Mary with many gardening skills, a love for cooking, being there for others, and her involvement with the church. Those who have met Mary, have lost a great, humble, and loving woman. She will be missed by many.
