Mark Sutton Obituary, Death – Greenwich Dentist Remembered After Battle With Cancer

Mark Robert Sutton of Greenwich, Connecticut, passed away late on October 8, 2026, following a courageous battle with colon cancer. He was 70 years old, just five days shy of his 71st birthday. His death has left his family, friends, patients, and the wider Greenwich community mourning a man remembered for his dedication to his profession, love of athletics, and deep commitment to those around him.

Born on October 13, 1955, in New Rochelle, New York, Mark was the son of Geraldine Juergens and Anthony Sutton. He grew up alongside his older brother, Christopher, and his three younger sisters, Elizabeth, Janine, and Karen. Throughout his life, he developed lasting friendships and built strong connections with the people who became part of his personal and professional journey.

Mark Sutton’s Education and Early Years

Mark attended Blessed Sacrament High School, where he played quarterback on the football team, earned the Most Valuable Player award, and formed friendships that continued throughout his life.

He later attended the University of Colorado Boulder, joining the Phi Delta Theta fraternity and participating in rugby and crew. He graduated with a degree in communications. During his college years, he also took part in a Semester at Sea program, travelling to destinations including Hawaii, South Korea, Hong Kong, India, Sri Lanka, Egypt, Tunisia, and Morocco.

Those experiences reflected his interest in exploring the world and connecting with people from different backgrounds. Years later, his daughter would take a similar journey, continuing a connection to that memorable chapter of his life.

Mark eventually settled in Greenwich, Connecticut, where he built his career, raised his family, and became part of a close-knit community that remained important to him.

A Dedicated Career in Dentistry

Mark established himself as a respected dentist in Greenwich, where he helped build Greenwich Dentistry into a trusted practice. He was known for his technical ability, extensive professional knowledge, and genuine concern for his patients.

His approach to dentistry extended beyond routine appointments. He placed importance on treating each person with attention and care, developing relationships with patients who valued his commitment and reliability.

Mark remained professionally active until his final days rather than retiring from the career he had devoted himself to for years. One of the special privileges of his later career was the opportunity to work alongside his son, Sean, during the final seven years of his professional life.

His work became an important part of his legacy, reflecting a commitment to service and a desire to make a difference in the lives of others.

Mark Sutton’s Love of Sports and Friendship

Outside his professional responsibilities, Mark had a longstanding passion for athletics and the friendships that grew from shared interests.

He ran the New York City Marathon four times and continued to enjoy an active lifestyle throughout his years in Greenwich. His regular activities included basketball, swimming, softball, and golf, giving him opportunities to reconnect with longtime friends while building new relationships.

Golf held a particularly special place in his life. He took pride in his game and celebrated a memorable hole-in-one in 2019. Yet his enjoyment of sports was not simply about competition or personal achievement. The companionship and laughter that came with spending time alongside friends were equally important to him.

Those who knew Mark will remember the enthusiasm he brought to these activities and the lasting friendships he maintained through them.

Family Was Mark Sutton’s Greatest Pride

Despite his professional accomplishments and many friendships, Mark’s greatest source of pride was his family. He was devoted to his wife, Nina Sutton, and took immense joy in watching his children build their own lives and careers.

He is survived by his wife, Nina; his daughter, Samantha Sutton, and her husband, Samuel Smythe, along with their children, John Smythe and Anderson Smythe; his son, Sean Sutton, and his wife, Caroline Sutton, along with their children, Cecilia Sutton and Beau Sutton; and his son, Scott Sutton.

Mark was remembered as a father who encouraged his children to pursue their ambitions while placing equal importance on kindness, thoughtfulness, and family relationships. His grandchildren brought him particular happiness, and their lives were a source of immense pride.

His parents, Geraldine Juergens and Anthony Sutton, preceded him in death.

A Courageous Battle With Cancer

During the final two years of his life, Mark faced colon cancer with extraordinary strength and determination. His family’s remembrance describes a difficult period in which his endurance gave loved ones precious additional time together.

Throughout that journey, Nina remained steadfastly by his side, supporting their family through an exceptionally challenging chapter. The time they shared during those final years became especially meaningful to those closest to him.

Mark passed away late on October 8, 2026, five days before his 71st birthday. His death marks the end of a life filled with professional dedication, personal achievement, enduring friendships, and deep family connections.
