In Loving Memory of John Thomas Dunne
John Thomas Dunne was a devoted son, loving husband, proud father, cherished grandfather, brother, uncle, and friend. Born in South Bend, Indiana, John lived a life rooted in empathy, curiosity, and deep human connection. He was the beloved husband of Karen, a loving father to Josh (Lindsay), Ryan, and Lauren (Christopher), and an adoring “Papa” to Cameron, who brought him immeasurable joy.
John was a man of deep empathy, feeling for others was woven into the very fabric of his being. He listened with intention, remembering the smallest details of even the most casual conversations, and therefore made everyone he encountered feel seen, heard, and valued. He found beauty and inspiration in people’s stories, treating each one as meaningful and worthy of reflection. His personality was truly magnetic—he had a rare ability to draw out the brightest parts of others and amplify them through kindness and compassion.
A natural optimist with an endless curiosity about the world, John marveled at both the extraordinary and the everyday—from scientific discoveries and technological advances to the perfect golf swing or admiring a full moon with his children. He enjoyed life’s simple pleasures, like watching a Knicks game with his dog on his lap and eating some dark chocolate, as much as he appreciated the excitement of travel, beach days, and family games.
John was the foundation and glue of his family. He always modeled selflessness, quiet strength, and compassion for others. He sacrificed for his loved ones without hesitation, guided them through their most challenging moments, and provided unwavering support. John taught his children to always lead with their hearts, to never fear failure, and to continuously grow through experience. John consistently modeled a fierce work ethic and dedication to his coworkers, putting his best in all that he did.
Though words can never fully express how deeply he is loved or how immensely he will be missed, John’s legacy lives on in the countless lives he touched and the family he built with care and devotion. He was, and will always remain, a bright light in the hearts of all who knew him.

When I think of John I picture “The Rock” A strong centered man who was able conquer anything for his family and goals

All of my love, Gina Giorgini
Such an extraordinary man.
Loved his family especially Karen his wife, his children and grandchild Cameron.
John was a beloved Son to his parents and brother to his siblings…..John never knew a stranger…Good Night Sweet Prince…
I was very proud of John from being a little boy to a wonderful husband, father, grandfather. He was always there for us no matter what was happening. I miss and love you John. RIP. My prayers are with you and your beautiful family..
My beloved cousin. Thank you for being you. You always stepped up and you always were there willing to give your arm for everyone. You stepped up as my brother when I lost mine and for that I can never say thank you enough. I am in disbelief bit I am so proud to have had you as my family. Karen, Lauren, Josh amd Ryan. I am so so sorry.
I knew John before Karen did, I’d like to think I was partly instrumental in getting them together. We’ve been friends for maybe 45 years. I’ve always called him one of my “boy” friends. I loved him dearly. His big smile, positive energy, love for his family…those who knew him know what I’m talking about. I will miss him terribly. My love, hugs, and thoughts are with all who knew him.
John always surprised me whenever we got together even if we haven’t seen each other in a long time. He always remembered the details about what we talked about the last time. He always asked how our kids and our grandkids are doing. And he wasn’t just asking just to make conversation but he really asked the details because he really cared. He was the most kind and thoughtful human being that you can imagine.
Even though we didn’t always see each other for a long time, when we did, we were just good friends even though a lot of time has passed in between and it really didn’t matter. It was like we saw each other last week or yesterday. RIP my good friend.
Love forever Marc & Debbie
I knew John throughout high chool and before that from our days playing CYO basketball. John was an excellent athlete and a great point guard. It’s amazing to read the tributes of a friend I haven’t seen or spoken with in 40+ years, but . . . .it’s amazing that the same beautiful things I remember about John are being written here now. John, was so sincere and so good. You never had to doubt John’s loving care or concern if you were with him. He looked directly at you, usually with that great smile of his, and he would just listen. Through his eyes and his ears, it was so clear that he was saying, “I love you.” God rest you, John. I am grateful to have known such a righteous, good man. I am sorry for the family’s huge loss.
This is Laurie Chipkin sending my heartfelt condolences
Such a gentle man with a kind heart and a generous soul. Our hearts are with you all at this difficult time. May your memories of John always be a blessing.
Shine on you crazy diamond.
It’s hard to find the right words to honor John, a great man who brought light into our lives. John wasn’t just a Colleague, he was a true friend. John was someone we could count on, someone who listened and cared. He made the most of challenging situations feel manageable. His dedication inspired us and his generosity touched us more than he ever knew. Thank you John, for the memories, the lessons and friendship. Rest in peace John. May Karen and her family find comfort in knowing how profoundly he was loved in the workplace.
Karen, I am so sorry to hear about John. My heart and love goes out to you and your beautiful family. I remember John as a fun, loving, welcoming person.
Karen, Josh, Ryan, Lauren, and family, our deepest sympathy to you all. Please know we will always be here for your family. May God give you strength, comfort, and peace during this very difficult time. John’s memory and legacy will live on in our hearts forever. Heaven has gained a beautiful soul. Rest in peace, our beloved friend.
“Blessed are those who mourn, for they shall be comforted.”
Matthew 5:4

This comes with a heavy heart and very sad one. To Karen, Josh, Ryan, and Lauren my wife and I will always have you in our thoughts and prayers!
John will be missed deeply! He was a great man!
From the time I met John the first time I knew he was special. I met him during superstorm Sandy. and worked with him on the “Project” he was not only a co-worker and partner, he was a mentor to me and we became brothers and family. He was always there for me. I will always remember the days in the office with him (Tiger), Phil (Doc) and I those days are missed.
I will miss my Brother forever and can’t wait to play golf with him on the other side!!
Love You My Brother , may you rest in peace!!!
Karen you will always be in my prayers!! God Bless You and the Children
Marty
