Born on August 16, 1936, in the Bronx, New York, to Anna Speciale and Andrew DiGiugno, Mark grew up on Westchester Avenue between Elder Avenue and Boynton Avenue alongside his brothers, Andrew and Angelo, and his sister, Dorothy. The Bronx remained a source of pride throughout his life, and many of the friendships he formed there endured for decades.
As a young man, Mark learned television repair during the early years of the industry's growth. Drawn to both technology and entrepreneurship, he and his friend Joe Bogdan opened Stage TV on Soundview Avenue in the Bronx, where Mark became a trusted repairman.
On January 10, 1969, he married the love of his life, Rose. Together they left the bustle of the Bronx and settled in Croton-on-Hudson, where they built their lifelong home and raised their family for more than fifty years.
After the birth of his son Craig in 1972, he focused increasingly on building a life closer to home. While continuing his work with Stage TV, he began laying the foundation for his own business from a makeshift workshop on his property, steadily developing a loyal customer base. Never afraid of hard work, he also pursued print modeling and took on construction jobs, including work on the iconic Chrysler Building.
In 1980, Mark fulfilled a lifelong dream by opening his own business, DeJuno TV Repair. What began in a home workshop grew into a successful business built on trust and personal service. As technology evolved, so did the business, and in the 1990s he expanded into video and game rentals, creating a familiar gathering place for generations of local families. For many, a visit to DeJuno TV Repair was as much about seeing “Mr. D” as it was about the service itself.
His work ethic was remarkable. In addition to running his business seven days a week, he worked for BOCES repairing audiovisual equipment for local schools. Whether helping a customer or solving a problem, Mark took pride in doing things the right way.
In the 2000s, Mark chose to slow down and spend more time with family. He worked as a crossing guard at CET Elementary School, a role he deeply valued because it kept him connected to the community. He took pride in helping children safely cross each day and found real fulfillment in looking out for their well-being.
Faith was an important part of Mark’s life. He attended church faithfully each Sunday and encouraged his family to do the same. For several years, he was a member of the church choir, where he found joy in worship, fellowship, and community. In his later years, he often found peace and comfort sitting on his deck overlooking the Croton River, reflecting quietly and finding strength in prayer.
Outside of work, Mark enjoyed getting lost in a good story. Whether through movies or television, he appreciated the characters and emotions that brought people together. He was especially fond of classic films, opera, Frank Sinatra, Joni James, and Luciano Pavarotti. A lifelong New York Yankees fan, Mark often said that growing up in the Bronx meant you were a Yankees fan.
He also found comfort in routine and community. Nearly every day, Mark could be found at the Croton Diner, sitting on the same stool, enjoying two cups of coffee. It was more than breakfast—it was a daily connection to community.
Friendship was one of the defining principles of Mark’s life. Many of his Bronx friendships endured for decades. Those friendships became so intertwined with family life that his children came to know many of them not simply as friends, but as aunts and uncles.
Over the years, customers and friends began calling him “Mr. D.” What began as an easier way to pronounce DiGiugno became a name of affection and respect. To many, “Mr. D” meant more than a business owner—it meant a friendly face, a helping hand, and someone who always made time for others. He had a natural ability to put people at ease and was rarely without a joke, a story, or a playful comment that made others laugh. His sense of humor was often delightfully childish, and he never lost the joy of making people smile.
Mark’s greatest legacy was the relationships he nurtured. He believed friendships were meant to last and invested in them with the same dedication he brought to his family and work. His customers became friends, his friends became family, and his warmth, humor, and loyalty left a lasting impression on all who knew him.
That legacy lives on through his children, grandchildren, and the many people whose lives he touched. The value he placed on friendship and connection continues across generations.
Mark was preceded in death by his beloved wife, Rose DiGiugno, and his brothers, Andrew and Angelo DiGiugno.
He is survived by his children, Mark DiGiugno Jr., Lisa Molinski, and Craig DiGiugno; five grandchildren; six great-grandchildren; one great-great-granddaughter; and his sister, Dorothy McManis.
Mark was a hardworking Bronx kid who became “Mr. D,” built a life and family in Croton-on-Hudson, and left behind a community of people who were better connected because he was part of their lives. He will be remembered with love, gratitude, and affection by family, friends, neighbors, and all who had the privilege of knowing him.
A Mass of Christian Burial will be held on Tuesday, June 30, at 10:00 a.m. at Holy Name of Mary Church, 110 Grand Street, Croton-on-Hudson, New York. Interment will immediately follow at Bethel Cemetery.
In lieu of flowers, the family invites donations toward a memorial bench honoring Mark's life and legacy. It is our hope that it will provide a place where family, friends, and neighbors can pause, reflect, and connect, just as Mark did throughout his life.
