Mark Sutton Obituary, Cause of Death - Greenwich Dentist Remembered for His Devotion to Family, Friends, and Community

Mark Robert Sutton, a respected dentist, devoted husband and father, proud grandfather, and cherished friend, passed away on October 8, 2026, following a courageous battle with colon cancer. Born on October 13, 1955, in New Rochelle, New York, Mark was just five days shy of his 71st birthday. His life was defined by professional dedication, a deep love of athletics, enduring friendships, and an unwavering commitment to the people around him.

His passing leaves a lasting legacy in Greenwich, Connecticut, where he built both a successful dental practice and a close-knit community of patients and friends.

Early Life and Education

Mark was born to Geraldine Juergens and Anthony Sutton and grew up in New Rochelle with his older brother, Christopher, and younger sisters, Elizabeth, Janine, and Karen. At Blessed Sacrament High School, he played quarterback for the football team, earned the Most Valuable Player award, and developed friendships that endured throughout his life.

He later attended the University of Colorado Boulder, joining Phi Delta Theta and participating in rugby and crew. He graduated with a degree in Communications and embarked on a Semester at Sea, traveling to destinations including Hawaii, South Korea, Hong Kong, India, Sri Lanka, Egypt, Tunisia, and Morocco. During those years, he met Nina Anderson, the woman who would become his lifelong partner.

A Remarkable Career and Calling in Dentistry

Mark's early professional life included a variety of jobs, from cab driver and security guard to lifeguard and bar back at Studio 54. He also pursued a career in entertainment as a stuntman in Los Angeles, working on productions including Splash, The Wanderers, Ghostbusters, and Saturday Night Live. He doubled for Robin Williams in The World According to Garp and The Survivors.

After returning to the East Coast, Mark continued stunt work before making a major career change. He enrolled at New York University to study dentistry, discovering a profession that became his true calling.

Mark eventually established himself in Greenwich, where he helped build Greenwich Dentistry into a trusted community practice. Patients valued his technical expertise, extensive knowledge, and personal approach to care. His commitment was extraordinary: he continued treating patients until his final days and spent the last seven years of his career working alongside his son, Sean.

Marriage, Family, and Lasting Friendships

Mark married Nina on August 24, 1985, aboard the Riveranda yacht on the Hudson River. They began their married life in Manhattan before moving to Greenwich as their family grew. Their marriage became a central part of a life grounded in love, loyalty, and shared experiences.

Although Mark achieved much professionally, his greatest pride came from his children and grandchildren. He encouraged his three children to pursue their ambitions while emphasizing kindness, thoughtfulness, and the importance of family. Their happiness brought him immense joy, as did the time he spent with his grandchildren.

Friendship was another defining part of Mark's life. His enthusiasm for athletics helped him maintain old friendships and form new ones throughout the years.

Athletics and a Love of Life

Mark ran the New York City Marathon four times and maintained a busy schedule of basketball, swimming, softball, and golf in Greenwich. He enjoyed the friendly competition as much as the company of those who joined him.

Although he joked about his inability to break 80 on the golf course, Mark achieved a memorable hole-in-one in 2019. The milestone reflected his sporting spirit, but the friendships surrounding the game mattered far more than any score.
