Mark Elliott Sedlacek entered this life on May 24, 1958, in Cedar Rapids, IA, the son of Marvin and Maxine Posusta Sedlacek. He attended school in Cedar Rapids, graduating with the Jefferson High School Class of 1976. Mark went on to further his education and nurture his love of the outdoors by attending Kirkwood and receiving his associate’s degree in forestry management. At an early age Mark had a love for nature and enjoyed hunting and trapping whenever he had a chance.
Mark began his career working as a park ranger for Geode State Park near Danville, IA before taking a job at Lacey State Park in Keosauqua. This move found Mark in the place that he would call home for the remainder of his life. On December 12, 1992, he married the love of his life, Maureen Morris. This was the first chapter in a love story that lasted over 33 years. With this union came the addition of stepchildren who were welcomed into the family and never thought of or treated as anything other than his kids.
Mark stepped away from his job as a park ranger to attend the Iowa Law Enforcement Academy and worked with the Van Buren County Sheriff’s Department. He eventually took a role as the golf course manager at the Riverview County Club in Keosauqua. During this time he raised pumpkins and it became a family affair. Eventually Mark decided to retire and truly “live his dream” of being a full-time produce farmer. Mark began raising all kinds of fruits and vegetables to sell at local farmers’ markets. While he took pride in nurturing his plants, his true joy came from sharing knowledge and creating memories with his grandchildren. In his off-season he spent countless hours working a trap line and was a lifetime member of the National Trappers Association.
His grandkids will forever remember all of the campfires with s’mores and hot dogs, BINGO at Christmas, the snacks he brought for every one of their sporting events, and ice cream trips after a day of hard work. He had a huge heart and a matching sense of humor that he shared with those around him. While he had a quiet presence… his actions spoke volumes. He will be deeply missed by his family, his friends, and the community that he called home.
Mark was preceded in death by his parents.
