Clark Niss
Clark Edward Niss, 84 years old, was born Dec. 22, 1934, and passed peacefully on Feb. 28, 2019, with family at his side. As many families have experienced, he passed due to complications from Alzheimer's disease.
Clark grew up in Elgin, Ill., and graduated from the University of Illinois with a degree in chemistry. He married the love of his life, Donna, in 1955. They had their first child, Susan, and then moved to Kansas City, Mo., in 1960, where the family added two more beautiful children, Diane and Steven. Clark was a leader in his church, community and business. He was president of St. Luke Lutheran Church Council in Fort Smith, North Kansas City Jaycees and Co-Plas, which he founded with Bill Weidman. Clark was also very proud of becoming an Eagle Scout. Clark and Bill sold Co-Plas, a manufacturer of gelcoat paint for the fiberglass industry in 1990. Shortly after selling Co-Plas, Clark and Donna retired to Naples, Fla., where he lived as a "snowbird." He then relocated to Tulsa in 2018 and moved to Legends Assisted Living Facility.
He was preceded in death by his parents, Charles and Madelynn Niss; and his daughter, Diane Niss. He is also preceded by Donna's brother, Warren "Flash" Gutschow.
Clark is survived by his wife, Donna; his daughter, Susan Sparks and husband Kevin with grandchildren Michelle and Michael and wife Rachel; and his son, Steven Niss and wife Sandy with grandchildren Madelyn and Lauren.
Clark loved to golf, having had four holes in one, garden, play cards and have margaritas by the pool, enjoying a "beautiful day" as it always was in Florida, according to Clark.
In lieu of flowers, please honor Clark with donations to your local Alzheimer's charity or the nearest Alzheimer's Association.
