John William Martell

Heaven is about to start having better barbecues! John William Martell was a remarkable man whose life was defined by extraordinary intelligence, unwavering integrity, relentless determination, a generous spirit, and a love for his family – and for grilling – that knew no bounds. He was a natural leader, a trusted adviser, a loyal friend, and a compassionate family man whose humor, wisdom, and kindness left an indelible mark on everyone fortunate enough to know him.

John passed away in Scottsdale, Arizona on October 26, 2026, after a courageous battle with pancreatic cancer. He was 65. Born in Toronto, Ontario, to William and Pauline (née Orme) Martell, John moved to the United States at age six. He entered the Christian Brothers directly after graduating from De La Salle High School in Walnut Creek, California where he was a novice before leaving the order. John credits the Christian Brothers with teaching him to teach. John graduated with honors from St. Mary’s College of California in 1984, earning a bachelor’s degree in theology with a minor in mathematics.

John’s entrepreneurial spirit emerged early. An exceptional swimmer who loved being in or on the water, he started a swimming-instruction business at age 12. His courage and swimming ability once saved a neighbor’s child from a river’s current. Throughout his life, John was driven by a deep desire to help others recognize their potential. From teaching and encouraging struggling students to coaching executives at Fortune 100 and 500 companies, he believed everyone deserved to feel valued, supported, and given the opportunity to succeed.

After a successful career in the insurance industry, John became a business consultant and executive coach. With his beloved wife, Patricia “Patty” Peyton, he cofounded Sphere International, a leadership and sales consulting, training, and coaching firm dedicated to helping people and organizations reach their potential.

Their love story began in the lobby of a Philadelphia building where Patty worked and John was interviewing for a job. Upon seeing her, John’s first thought was, “You’re going to marry her.” His next thought was, “You’re out of your mind.” Despite those doubts, his instinct was right. Patty became the love of his life, closest partner, and tremendousl blessing.

Above all, John’s greatest joy was his family. To his three children, Matthew, Adam, and Gabrielle, he was their rock, protector, superhero, and forever “Dadman”—the person who could solve any problem and make them believe anything was possible. He worked tirelessly to give his family a wonderful life, but his happiest moments were simply having everyone together, sharing stories, laughter, and a good meal.

John had a gift for making people feel loved, welcomed, and believed in. His gentle spirit, remarkable wisdom, and incredible sense of humor drew people to him. He always seemed to know just the right words to say, whether offering heartfelt advice, delivering a difficult message, or telling a perfectly timed joke that brought laughter even in life’s hardest moments. He delighted in traveling, sailing, cooking on one of his five grills, and gathering family and friends around his table.

John was eagerly anticipating the arrival of his first grandchild, due December 27. Though deeply saddened that he would not meet the baby, he faced his illness with extraordinary determination and endless hope. His family is grateful for the prayers, encouragement, and love that surrounded him.

John was predeceased by his parents, William and Pauline, and his brother, David. He is survived by his wife, Patty; his children, Matthew, Adam (Daphne), and Gabrielle; his siblings, Michael (Maria), Kenneth (Ellen), and Diane (Alex); and many adoring nieces and nephews.

John leaves behind a legacy of kindness, strength, generosity, and unconditional love. Whether rescuing a child, encouraging a struggling student, coaching a leader, or welcoming loved ones to his table, he made a lasting difference through his courage, wisdom, humor, and unwavering belief in others.

He will be remembered with admiration, celebrated with laughter, and loved beyond measure.
