Very sorry for your loss. Jack was a great man, someone our whole family admired. Wish I had gotten to see him one more time. May his memory be a blessing to all of us.
God bless the DiCostanzo family. May Giacomo rest in peace.
Rest easy Uncle Jack,you put up a good fight against cancer.Thanks for always being humble and a good husband to Aunt Nancy and loving Dad to Maria&John.
Our beloved Uncle Jack was a gentle man and a gentle soul. He was an accomplished architect, skilled in his field, and dedicated to his work. He was very proud of his Italian heritage and a person deeply committed to his Roman Catholic Faith. But more than anything he loved his wife Nancy and children John Sebastian and Maria Lucia. Family was first and foremost everything to him. He endured his cancer illness with great resolve, courage, and dignity, never allowing it to change him. His suffering is finally over. We pray that he rest in peace. He will be deeply missed.
I am unable to put down just One memory of my Uncle. Uncle Jack was more than just one memory. Throughout his life he live up to his high standards and had a wonderful sense of integrity. He was a good man. He always tried his best. He loved his family.
Our deepest condolences to the DiCostanzo family. Wishing you strength and comfort during this challenging time.
