A cause of death was not immediately revealed.
A retired lieutenant colonel in the U.S. Air Force, Maduli followed a decorated military career with a long tenure in community college administration in Northern and Southern California, including as vice president of business services at Las Positas College in Livermore.
He was elected to the CLPCCD board as the representative for Trustee Area 7, incorporating Livermore and parts of eastern Dublin and southeastern San Ramon, in 2016 and earned a second full term in 2020 after running unchallenged. He served twice as president of the board.
"We will be forever grateful to Trustee Maduli for his dedication, expertise, and deep commitment to serving our communities," CLPCCD Board President Tim Sbranti, of Dublin, said in a statement on June 15. "It has been a privilege for me and for my fellow board members to work alongside Trustee Maduli. He will be greatly missed."
District Chancellor Ronald Gerhard added, "I have had the honor of knowing and working with Trustee Maduli in various capacities for over a decade. I am very saddened by his passing and will forever be appreciative of his impact to our district and colleges. The CLPCCD family offers our thoughts and support to the Maduli family at this time."
Maduli is survived by his wife Cyril, two children and four grandchildren. Details on memorial services are pending.
"He was a strong mainstay figure in our educational community, and a voice for all who were fortunate to have known and worked with him," Livermore Valley Joint Unified School District Superintendent Kelly Bowers told the Weekly.
"We are grateful for his time with the Chabot-Las Positas Community College District, I know he will be greatly missed. I, along with the entire LVJUSD, offer our sympathies to his family and all those that worked with and cared for him," she added.
Maduli served in the U.S. Air Force for more than 20 years, receiving a range of military awards before retiring as a lieutenant colonel.
His career in community colleges included working as vice chancellor of administrative services for the West Valley Mission Community College District, assistant superintendent/vice president of administrative services and later interim superintendent/president for the San Luis Obispo County Community College District and vice president of business services for Las Positas College.
A graduate of the military's Armed Forces Staff College and the Air Command and Staff College, Maduli earned his associate's degree from Hartnell College, bachelor's degree from Cal Poly, master's degree from the University of Oklahoma and another master's from Golden Gate University.
At the time of his death, Maduli was working toward completing a doctoral degree in educational leadership from the University of Southern California.
Maduli is the third CLPCCD trustee to die in office during the past three years. Castro Valley representative Donald "Dobie" Gelles died of congestive heart failure in May 2019, and Trustee Marshall Mitzman died from COVID-19 while in a recovery care center in Hayward early in the pandemic in April 2020.
