William John Martinoli Sr., 77, passed away unexpectedly in his home on June 15, 2026. A devoted father, husband, proud grandfather, uncle, and respected leader in the construction industry, Bill lived a life defined by hard work, integrity, and a deep commitment to the people he loved with an unwavering devotion to his family. He left a lasting impact on countless lives. The lessons he taught us and the values he instilled and lived by will remain with us forever.
Bill is survived by his two children, William John Martinoli II and Cara Joan Martinoli, his daughter in law Julie Anne Martinoli, and his cherished grandchildren, Nicholas and Marianne, who brought him immense pride. He is also survived by his wife, Natalia Ivianivna Prokopenno Martinoli, and by many nieces and nephews who knew him as a steady, supportive uncle. Bill shared many cherished years with his first wife, his high-school sweetheart, Joan Marie Martinoli, the mother of his two children, who passed after a battle with Lung Cancer in 2002.
In his early years he was exceptional in every sport he participated in becoming State Champion in wrestling, football and baseball during high-school. He was also part of the marching band and would sing in the choir and ultimately earn a full scholarship to go to Europe to sing, which he chose not to pursue. A gifted athlete, he accepted a full football scholarship to Boston College, where he also would wrestle.
Bill was never paralyzed by the unknown. Whether it was a new hobby or a business opportunity, he would immerse himself in research until he had mastered the subject, often becoming more knowledgeable than anyone around him. He possessed a remarkable gift for courage with the willingness to step forward when others hesitated or never tried at all. He lived life on his own terms, guided by conviction rather than convention. His confidence, determination, and fearlessness allowed him to pursue opportunities that many would have considered beyond reach.
One of his defining qualities was his resilience. He taught his children that when times are tough, he would often say, "pick yourself up by your bootstraps". It was more than a saying to him, it was a way of life. He believed in perseverance above all else and during hard times to keep moving forward no matter the challenge. He would face adversity head on with courage and determination.
Across nearly five decades in the construction industry, Bill built a reputation as a superintendent, project manager, Vice President, and company owner who could steady any job, solve any problem, and lead any team. He was unmatched in his ability to find errors in plans long before they reached the field, and he was legendary for his skill in identifying, documenting, and negotiating change orders which often turned design oversights into opportunities that protected schedules, budgets, and the integrity of the work. His work spanned houses, apartment buildings, restaurants, VA hospitals, gamma ray vaults, major civil engineering projects, bridges, utilities, multi family developments, and large scale infrastructure across Missouri, Kansas, Arkansas, Louisiana, Washington, Idaho, Boston, New Hampshire, Massachusetts, New England, and beyond.
Bill believed in hard work, straight talk, and doing things right the first time. He mentored countless people, steadied countless projects, and left behind a legacy measured not only in concrete and steel, and wood structures, but in the lives he touched and the family who loved him.
He will be remembered for the love he shared with his family and friends, his unwavering strength, his honesty, and the pride he took in every endeavor. A celebration of life will be announced by the family at a later date.
In lieu of flowers, that family asks that you honor Bill's legacy of learning and teaching by seeking new knowledge, pushing beyond the boundaries of the known, and sharing what you discover with others.
