John "Jack" Julius Muldoon

John (Jack) Muldoon, 80, passed away Friday, March 24, 2023 in Denver, CO after a long and hard fought battle with Multiple Myeloma.  He remained the life of the party until the very end, bringing much joy and laughter to his friends, family and many healthcare providers over the last few weeks (and years).

Jack is survived by his sons, John E. and Brian J.; his brothers, Robert, Barry, and Michael, and beloved grandchildren, Brandon, Cassie, Jack H., Hannah, and McKenna, as well as his Godson, Richard Harris  He was eagerly awaiting the birth of his first great grandchild when he passed.  He was predeceased by his son, Robbie, in 1976 and his wife Maryanne in 2018.  

Jack met the love of his life, his late wife, Maryanne, in high school and often credited her with helping him graduate (having seen his report cards we all agree wholeheartedly). She went on to help him navigate life for nearly the next sixty years. She was his rock and support, and many friends and family members remember the multitude of parties and gatherings at their home.  The tables turned in 2018 when she became too sick to take care of herself.  Jack stepped up and showed the strength of his love, taking care of her tirelessly in those last months, despite his own cancer.  

Jack had a long career as an airplane mechanic, beginning with New York Airways and ending 50 years later with an Inspector position with the FAA in Denver, CO where he was awarded with accommodations recognizing his security work during the 2002 Utah Olympics and The Charles Taylor Master Mechanic Award. 

In between the beginning and end of his career, he spent over two decades working as the Director of Maintenance for Windstar Aviation, a jet charter service owned by John Denver which served as John’s primary tour jet and a private jet charter service. John Denver moved Jack and his family to Denver from Central Islip, NY in 1977 to help run the company.  The stories from those years are many and there just is not enough room here to give them credit, but suffice it to say that that many a good time was had by all while working hard in a demanding world with some amazing professionals.

Jack “never met a stranger” and had a multitude of amazing life long friends from Long Island to Colorado.  The list is just too long, but, given his love….and you are reading this, you know who you are and you know that he loved you very much.

In his last years, besides visiting with friends and family, he loved getting on his scooter, and taking the train to watch the Rockies games at McGregor’s Square, where he got to know everyone, from the bartenders to the cleaning staff.  He made friends there - good friends who took him out to dinner and even at their house.  Other friends often took him to the doctor, others visited with him and even adopted his dog JoJo, when Jack was unable to care for him.

And in these later years, Jack also made friends on trips out East to visit family, often holding court at his son’s Inn in Maryland,  The staff there adored him and guests loved him. He also made friends at his new apartment building in Denver.  He made friends with his doctors, his PT and OT helpers, and even more friends at his recent blood transfusions and trips to the ER.  He may be the only man in history who asked the day that he died when his next chemo was because he missed everyone there.  

Jack Muldoon loved his friends and family deeply and unconditionally.  He made everyone feel like they were his favorite person in the whole world.  He was never a rich man, but he would give you the shirt off his back to help any family or friends in need.  Of course, he would likely buy a similar shirt at Goodwill the next day, but that was Jack.

Despite the death of his son, his wife, and his battle with cancer, he never stopped loving and living life up to the very end.  In honor of his love of life, the family will be holding a Celebration of Life on Sunday, April 16, 2023 at Overture Central Park, 8133 E 29th Place, Denver, CO 80238 from 11 am - 1 pm, to be followed by a very optional and very casual gathering at McGregor Square at 2 pm to watch the Rockies game on the big screen (Jack’s favorite place to watch the game).  Please RSVP at this link: https://www.vandiverinn.com/tickets

The family is also hoping to create an “East Coast Family” Celebration for Jack later this summer.
