John H. Sharkey Jr., a legendary figure in the martial arts community and an influential mentor to countless students, passed away peacefully on January 25, 2026, at the age of 69. Born on February 27, 1956, in Momence, Illinois, John lived a life defined by his unwavering commitment to karate, service, and his community.
John’s legacy began with his passion for martial arts, which led him to found Sharkey’s Karate Studio in Naperville, Illinois in 1973. Over the decades, his dojo became a renowned training ground for students who would go on to achieve success in both competitive karate and the entertainment industry. Known for producing Hollywood stuntmen and martial artists, Sharkey’s students starred in movies like “Everything Everywhere All at Once” and popular TV shows such as “Cobra Kai” and **“Power Rangers.” However, beyond the accolades, John’s impact was rooted in the values of discipline, service, and personal growth he instilled in those he mentored.
Sharkey’s philosophy was grounded in helping young people build character, and he was known for opening his home to students in difficult circumstances. Whether they faced family challenges or personal hardships, John always sought to provide support. According to his longtime student Juan Hernandez, “He had a remarkable ability to see the potential in young people when no one else could. He believed in everyone and worked tirelessly to help them succeed.”
Throughout his martial arts career, John Sharkey also held prestigious leadership positions. In 1977, he became the President of the American Karate Association (AKA), and he led Team AKA, one of the top sport karate teams in the world. His leadership in the Sideswipe Performance Team further solidified his place as a prominent figure in the martial arts world. Sharkey traveled internationally, not only to promote karate but also to entertain and support U.S. troops stationed overseas, a testament to his deep sense of duty and community service.
Despite his international reputation, Sharkey was humble and dedicated to the craft. He rarely sought attention, preferring instead to focus on his students and their development. His rigorous standards for karate excellence were clear—since opening his dojo, he awarded only 164 black belts, a number that reflects his belief in quality over quantity. Students who earned a black belt under Sharkey’s tutelage knew they had truly earned it through hard work and perseverance.
One of John’s most significant influences was on Mike Chaturantabut, who became the Blue Power Ranger in the television series “Power Rangers Lightspeed Rescue.” Chaturantabut recalls how Sharkey took him under his wing, going above and beyond to support his career in martial arts and Hollywood. Sharkey drove him across the country to receive specialized training and later helped Chaturantabut make the difficult decision to pursue his dreams in California. “John believed in me when no one else did,” said Chaturantabut. “He showed me that with hard work and dedication, anything is possible.”
John was a passionate advocate for martial arts but also had a deep love for his personal hobbies. He was an active member of the National Pigeon Club and the Kankakee County Fair Association, where he enjoyed spending his leisure time tending to his farm, caring for his chickens, and reflecting in peace.
John is survived by his sister Julie Dinkins, brothers Tony and Jim Lampley, as well as his cherished dog, Dunkin. He also leaves behind a legacy of students, black belts, and friends who were deeply impacted by his guidance, support, and mentorship. His closest friends and colleagues—Hunter B. Lyon of Chicago, Stephen Bratton of Naperville, and Juan Hernandez of Beecher—were among those who stood by his side through the years.
He was preceded in death by his parents, John and Mary Sharkey, brother Bob Lampley, nephew Adam Lamb, and great-nephew Jacob Lamb.
A Memorial Visitation will be held on February 14, 2026, from 1:00 pm to 5:00 pm at Blake-Lamb Funeral Home in Oak Lawn, IL. Following the visitation, services will be private.
In honor of his contributions to martial arts and his lifelong commitment to helping others, a group of his students will posthumously award John the highest rank of 10th-degree black belt, a recognition he humbly declined during his lifetime, believing there was always more to learn.
John H. Sharkey’s life was a testament to the power of belief, mentorship, and selflessness. His impact on the martial arts community, and the lives of his students, will be felt for generations to come.
