Mark Cassidy

Mark Douglas "Dancer" Cassidy passed away on February 2, 2026, in Port Orange, Florida, after a long and courageous battle with cancer. He was 67 years old. At the time of his passing, he was surrounded by love and comfort, with his little dog Yuki snuggled by his side.

Born on July 25, 1958, in Hartford, Connecticut, Mark was the beloved son of Lynette Gloria Goulet (Cassidy) McCarter and Francis "Red" Edward Cassidy, both of whom preceded him in death. Raised in East Killingly, Connecticut, Mark's early years were shaped by a strong work ethic and deep family bonds. At just 14 years old, he began his career as an electrician under the mentorship of his father. He graduated from Ellis Vocational Technical School in 1976 and soon after joined the U.S. Army to further his studies in Electrical and Communications.

Mark served honorably in the Army and was stationed in Germany, where he embraced the opportunity to explore Europe. After his discharge, he reunited with family in Daytona Beach, Florida, before continuing his electrical career alongside his father in Greenville, South Carolina. Eventually settling in Sierra Vista, Arizona, Mark became known not only for his technical expertise but also for his generosity in sharing that knowledge. He mentored many aspiring electricians who still remember him as "the BEST electrician they ever knew," capable of "talking wires out of the wall."

Later in life, Mark transitioned into retail management roles at Circle K convenience stores in both Sierra Vista and Jarrell, Texas. Though he stepped away from electrical work professionally, he never lost his passion for it or for teaching others.

Sierra Vista also became the backdrop for one of Mark's greatest passions—motorcycles. He founded The Nomaden INTL MC (now The Nomaden MC), where he earned the nickname "Dancer" and held numerous leadership roles including Road Captain, Secretary, Sergeant of Arms, and Treasurer. His time with The Nomaden was marked by camaraderie and community service, including large-scale toy drives for Toys for Tots. Later, he joined The Huns of the Southwest motorcycle club and rose to become Governor of the Sierra Vista Chapter. Whether riding under desert skies or working on bikes with loved ones, motorcycles were a defining part of Mark's life.

On May 28, 2001, Mark married Sondra in Las Vegas while living in Sierra Vista. Together they welcomed their daughter Erin Michelle Cassidy—Mark's proudest accomplishment and the light of his life. Though their marriage ended in divorce, Mark and Sondra remained close friends throughout his life. A devoted father from day one, Mark shared everything he loved with Erin: movies, music, adventure, motorcycles, and animals. He volunteered in her classroom during her early years and delighted in recounting stories about her to his sisters and mother.

Mark's role as a big brother to four younger sisters was one he embraced wholeheartedly from a young age. Whether taking them on adventures or offering a watchful eye with a smile, Mark's bond with his siblings remained strong throughout his life. In his final months battling cancer, he was lovingly cared for by two of his sisters in Daytona Beach and Port Orange—a time filled with reconnection and cherished memories.

He leaves behind a legacy of love and resilience that lives on through those who knew him best: his beloved daughter Erin; ex-wife Sondra; Aunt Janice; siblings Tori (Joe), Tracy, Kelly (Rick), and Shannon (Brandon); seven nieces and nephews—Zachary, Dylan, Robert, Eric, Bria, Ciara, and Tye; as well as three great-grand-nieces and nephews—Elowyn, Grayson, and Finn.

Mark lived fully—as a lover and fighter; a son and brother; a husband and father; a teacher and leader; a man who found joy under open skies on two wheels. His spirit will continue to ride on through every story told around a campfire or every engine revved in tribute. He had three rules in life "hots on the left, colds on the right and shit rolls down hills; keep the rubber side down and try not to ride faster than your guardian angel can fly."

May Mark's memory bring comfort to all who knew him—and may he forever ride free beneath endless skies.
