Tan Duy Phung

Tan Phung lights up every room with his personality, his infectious laughter, and his engaging, talkative nature.


TTan Phung, beloved father, husband, and grandfather, passed away peacefully on April 3, 2024 surrounded by family at Hoag Memorial Hospital in Irvine CA. Tan was born on October 22, 1956, a man whose presence and warmth enveloped all those around him.

Tan is survived by his loving wife, Kathleen Phung, whom he married in 1981 in Santa Monica CA. Together, they created a beautiful family and instilled in them the values of love, respect, and integrity. His legacy is carried on by his devoted children, Theresa Vuong and Tan Phung Jr., and cherished grandchildren, Davin and Audrey Vuong.

Tan's life was punctuated by moments of joy - the successful startup of his company, Modern Information Systems in 1982, the birth of his first child in 1983, the arrival of his second in 1987, and becoming a grandfather in 2016 and 2018. His children and grandchildren were his pride and joy and he was celebrated as the "World's Greatest Grandpa."  Warm, friendly, and always full of stories, Tan was someone who brought light into every room he entered. Known for his jovial nature, he was a talkative jokester who never failed to bring a smile to those he interacted with.

Tan enjoyed simple pleasures of life. His pastime included being with his grandchildren, fishing, and capturing precious memories through his lens. His favorite game to play was Chinese Chess - a testament to his strategic mind, and ping pong - he was a champion. A fan of Kenny Rogers’ music, Tan often filled the house with his favorite tunes. And, his favorite movies were Bruce Lee's, which he would watch over and over again.  Tan also enjoys writing poetry for his wife, who when asked rolls her eyes and lovingly complains ‘all the time’. During his cancer journey, Tan realized his gift at sharing emotions through prose and expanded to writing impactful poems to share with the cancer community.

Tan is proud of the life he built.  Coming to the United States in 1975 as a refugee, he overcame the obstacles of language and culture.  He pushed himself to grow personally, professionally, and adapt to the completely new world.  He relied on himself and his life was filled with joy, warmth, and lots of laughter, qualities he passed on to his beloved children and grandchildren. His spirit will live on through the love and memories he has left behind. He will be deeply missed by all who knew him.

Here is one of Tan Phung's poems titled Embrace of Solace: 

In a room where silence speaks,
A soul endures, both brave and weak.
O cancer, unbidden, why choose me,
To bear this burden, this relentless sea?

Eyes, once the home of hopeful gleams,
Now harbor quiet, pain-filled dreams.
In each pang, a constant fight,
Yet in the depths, a flicker of light.

Through this storm, I seek a grace,
A gentle peace in this harsh place.
In every pain, in every sigh,
I look for strength, as days go by.

The clock's hands march, relentless, true,
Marking moments, both old and new.
How long must I endure this test,
To find some rest, to find some rest?

Yet, even as tears trace sorrow's line,
A glimmer of hope, subtly divine.
Life, in its fleeting, fragile span,
Reveals the depth of the human clan.

To those who read, with hearts that feel,
Know this journey is profoundly real.
In each word, a silent cry,
For compassion, for a tender sigh.

O cancer, though you've taken much,
You've not dimmed the human touch.
In struggle, in pain, in quiet defiance,
Lies a soul's unyielding resilience.


Phung family immigrated from Vietnam to the US
During a time of turbulent civil war, the Phung family was sponsored and came to the US.  
Joined the Church of Jesus Christ of Latter-Day Saints 
Tan Phung dedicated two years of his life to missionary work, demonstrating unwavering devotion. His journey lead him to adventures in North Dakota and California. Through these experiences, his spiritual and personal growth became evident, shaping him into the individual he was destined to become.
Meet his future wife
During one of his missionary visits, Tan knocked on a door that would change the course of his life forever. It was there that he encountered his future wife, marking the beginning of a remarkable journey together.
Got married
On June 20th, 1981, Tan and Kathleen exchanged vows in a sacred ceremony in Santa Monica, California. Their wedding was a grand celebration with a four-tiered wedding cake and the presence of 180 guests. Amidst the joy and nervousness of the occasion, Kathleen's excitement led to a humorous mishap during the cake feeding, as she accidentally directed the fork towards Tan's nose instead of his mouth!
Founded Modern Information Systems
Together with his wife, Kathleen Phung, Tan established Modern Information Systems, a pioneering company at the forefront of technology. As one of the only Asian individuals in the field in the US during that era, Tan forged valuable connections with Japan, introducing Fujitsu technology such as RAM chips, hard drives, and floppy disks to the early landscape of computer hardware. 
Daughter was born
Theresa Vuong was born on October 1983 and was delivered two weeks after her expected delivery date.  Tan was immensely proud of having his first healthy child and was happy that he recently purchased his first new house.  He was living the American dream!  
Son was born
Tan Phung Jr was born on November 1987 and was gifted what his father cherished most - his name.  In Vietnamese culture, a name holds significant symbolism, reflecting the importance of family and status.  Tan bestowed upon his son a powerful name, ensuring that he would begin his journey in the world with strength and honor.
Grandson was born
Davin Vuong was born on May 2016, 6 weeks before his due date.  In a moment of need, Tan Phung, stepped up as retired grandpa to take care of his grandson while mama went back to work.  We all had our concerns and hesitations with the setup, but Tan was a natural and absolutely amazing to take care of Davin.   Their bond as grandpa and grandson flourished.
Granddaughter was born
Audrey Vuong was born on April 2018 and grandpa was one of the first to hold her.  He was amazing trying to juggle watching two kids and taking them to Gymboree and the park!
