John Paul Reynoso passed away on March 9 after suffering a sudden heart attack. He was born and raised in Phoenix, Arizona, where he spent his early years before pursuing a life defined by service, intellect, kindness, and a deep love for his family.
John attended the University of Arizona, where he pursued his passion for science and engineering before going on to earn a Master’s degree in Nuclear Engineering. His commitment to serving his country led him to become an officer in the United States Navy, where he proudly served from 1977 to 1982, including time aboard the submarine USS Haddock (SSN-621).
Following his military service, John built a distinguished career as a nuclear engineer. He eventually served as a Lead Inspector for the U.S. Nuclear Regulatory Commission, where he dedicated many years ensuring the safety and reliability of nuclear facilities before retiring.
While John was accomplished professionally, his greatest pride was his family. He loved spending time with his children and grandchildren and cherished every opportunity to be together. Whether boating, enjoying the outdoors, or simply striking up a conversation with someone new, John had a natural ability to bring people together. He was known for his warmth, his easy ability to make friends, and the genuine kindness he showed to everyone he met.
John is survived by his loving wife, Debbie Reynoso; his son, John Reynoso; and his daughter, Ana Reynoso. He was also a proud stepfather to Debbie’s daughters, Amie and Stephanie.
John leaves behind many beloved grandchildren: Tatum and Tyler (children of John); Gavin, Holden, and Beckham (children of Amie); Wittley and Wilder (children of Stephanie); and Winnie (daughter of Ana). His role as a grandfather brought him immense joy, and he treasured the time he spent with each of them.
John lived by a simple philosophy: be kind to everyone and treat everyone with respect. Those who knew him will remember him for the way he lived those words every day.
John’s legacy of kindness, friendship, and love for family will continue to guide those who were fortunate enough to know him. His greatest legacy lives on in the family he loved so deeply and in the many lives he touched through his service, generosity, and unwavering respect for others.
“Well done, good and faithful servant.” — Matthew 25:23
