Dennis George Lisi

We celebrate the life of Dennis George Lisi, 84, who passed away peacefully on Thursday, July 30, 2026, at his home in Gainesville, Virginia. Dennis was a devoted husband, father, grandfather, brother, veteran, and friend whose life was defined by faith, hard work, and devotion to his family. Born on November 18, 1941, in Chicago, Illinois, Dennis was the son of David and Adele Lisi. He attended DePaul Academy in Chicago, graduated from Crystal Lake High School, and earned a Bachelor of Science degree in Aviation Maintenance Management from Lewis University. His early work at Chicago’s O'Hare International Airport sparked a lifelong passion for aviation and ultimately led to a long and successful career with Exxon Mobil Corporation. He met his wife, Patricia, at a high school “sock hop” in 1959, married in 1967, and remained a devoted husband for 55 years. The truest expression of that devotion came in Patricia's final years, when he selflessly cared for her each day with patience and constant attention to her comfort. Through every chapter of life, they remained loyal companions, creating a home grounded in faith, family, and unconditional love. Answering the call to serve his country, Dennis served in the United States Army during the Vietnam War and was awarded the Air Medal for meritorious achievement. His military service reflected the courage and quiet resilience that would remain hallmarks of his character throughout his life. Following his military service, he continued building a career defined by dedication, integrity, and professionalism. His work with Mobil Oil afforded his family the extraordinary opportunity to live around the world, including nine years in Saudi Arabia and three years in Nigeria, along with countless travels and adventures along the way. Eventually, Dennis' career brought his family to Virginia, where they made their home for the last 35 years. However, no matter where life led him, he always remained a Chicagoan at heart. Above all else, Dennis was devoted to his family. He believed that providing for those he loved was both his greatest responsibility and privilege. He was generous without seeking recognition, responsible without complaint, ethical in every aspect of his life, humble in his accomplishments, and quietly steadfast through every challenge. Stoic by nature, Dennis possessed a subtle sense of humor, often communicated with nothing more than the raise of an eyebrow that could speak volumes and bring a smile to those who knew him best. Dennis had a lifelong love of sports, especially golf and baseball. He looked forward to spending time on the golf course just as much as he enjoyed watching his favorite players compete for major championships. One of his fondest childhood memories was meeting his baseball hero, Andy Pafko. He was a loyal fan of his hometown Chicago Cubs, but also appreciated the talent of many great players, regardless of the jersey they wore. He was also an avid fan of college basketball, especially the University of Virginia. Dennis appreciated nature, to include watching the birds and deer in his backyard, colorful sunsets, and summer thunderstorms. He was also known for his sweet tooth and loved a bowl of good ice cream or his daughter’s homemade chocolate chip cookies. Dennis was a man of deep Catholic faith, living his beliefs not only through prayer but through compassion, humility, and generosity toward others. Those who knew him believe that it was his faith that carried him through the most difficult moment of his life: the loss of his beloved sons, Christopher and Brian, in 2016. His faith continued to guide him in recent years as well, where he faced the challenges of Parkinson's disease with remarkable grace, dignity, and acceptance. Dennis is survived by his daughter, Monica; his granddaughter, Kristie; his brothers, David, Daniel, and Dean; his sister, Donna; and numerous cousins, nieces, and nephews. He was preceded in death by his parents, his wife, and his sons. A funeral Mass service will take place at All Saints Catholic Church in Manassas, Virginia on Thursday, August 6th at 1 p.m. Visitation will be afterwards from 5-8 p.m. at Pierce Funeral Home. For those who attend the Mass and wish to stay for the visitation, the family invites you to join them from 2-5 p.m. for refreshments. In memory of Dennis, donations can be made to the Society of St. Vincent de Paul.
