Mark Roosevelt

Mark A. Roosevelt, 64, husband of Lynn Nanney Roosevelt for 40 years, died May 8, 2026, due to complications of Parkinson’s Disease. Despite increasing pain and mounting disabilities, he managed to help others and maintain a good humor.

He was born in Syracuse, NY, to Ernest Roosevelt and Pat Yamrozy Roosevelt. His early years were spent in New York State and western Massachusetts, and when he was 11, his father took a position with GE and moved the family to Greenville. Except for a six-month stay in France during high school, when his father was with Michelin, he lived the rest of his life in Greenville.

Mark was the second of four boys and fondly remembered water skiing at Lake Hartwell, hated the fishing jaunts, and had eternal memories and laughs about a family camping trip out west with the same five 8-track tapes blaring over and over. He was very proud of being an Eagle Scout and a school bus driver in high school, and he did sound and lights both in Greenville Memorial Auditorium and J. L. Mann High School when he was in school there. When he was growing up, he adored his family dog, PJ, as well as riding anywhere with his Grandpa John.

With a BA from Furman in business and his college years doing co-op in computer programming for Liberty Life Insurance Company, Mark took his first computer position there and spent the rest of his career in technology, telecom, and related marketing and sales positions.

Mark’s roles in the tech field were extensive. He programmed, was a computer security advisor and a project manager, but his favorite position was speaking internationally on computer technology and telecom for IBM, Computer Associates, Siemens, and other global companies. His audiences ranged in size from 250 to 1000, and not only did he create compelling visuals and three-hour presentations but the live technology demos that went with them. Lynn often worked with him, especially after they started their own company in 1997.

His love of travel was whetted by his time in France and a Furman foreign study in England, and Mark and Lynn traveled around the world, both for business and pleasure. Holding a koala in Australia was one of his travel highlights during a six-week business trip to Asia and Australia. Passions were running (up to 12 miles a day), kayaking, mountain biking, movies, and doing anything with Lynn.

Few people knew of the difficulty of Mark and Lynn’s life over the past decades. Visits to doctors, urgent care, the hospital, and various therapies occurred multiple times a week. Because of his health issues, Mark stopped working in 2014. His Parkinson’s, diagnosed in 2020, moved quickly. His inability to walk and speak were hardships for both of them, stopping walks together, discussions, and laughs. They both tried hard to maintain a good demeanor, whether in the world or in the ER.

Within two years of diagnosis he was wheelchair-bound and in assisted living at the Blake at Hollingsworth Park, where he participated in nearly every activity and had many friends both among residents and the staff. The last five months of his life were spent at NHC Greenville, where he created constant laughter for the staff and friends on his entire unit, despite his lack of voice. Mark’s wheelchair collisions with furniture were legend, and he was always ready to share a snack and a hug. His last days there were full of love from the staff and his friends there and his favorite snack, and MegaStuff Oreos on his bedside table. He adored funny tee shirts, and his favorite said, “I’m not drunk, I have Parkinson’s.”

Mark was predeceased by his parents. In addition to his wife, Lynn, he leaves his three brothers: Mike and wife, Jane; Matt and wife, Cindy; and Paul and wife, Margaret; his nieces Megan and husband; Shadrey, Lauren and husband, Tony; Jenna and fiancé, Dayton; and nephews John and wife, Alyssa; and Dustin and wife, Sarah; plus several great-nieces and nephews. His close friends will miss him, especially dear friends Francis Anderson and wife, Oyku Uner, and special friends James and Cathy Logan. Kylee Heap and her mother, Mary Jean Heap, provided friendship, silly craft projects, and absurdity at NHC, plus Christmas cheer for every occasion. Numerous others, both strangers and friends on multiple continents, supported Mark and Lynn on the lengthy journey of his diminishing health. And of course the very special staff at NHC Greenville offered devoted care, hysterical laughter, and hugs daily.

We are especially thankful to his doctors at St. Francis Eastside for decades of superb care as well as to the many other doctors and medical professionals he saw over 25 years. He will be cremated and his ashes scattered privately. Donations in his honor can be made to the Parkinson’s Foundation. To remember him, laugh with everyone and be kind.
