Dennis Lynn Jarvis, age 73, entered eternal rest on February 28, 2024, in St. Louis, Missouri. Dennis was a passionate individual with a variety of interests. His hobbies included hiking, mushroom hunting, topography, cave exploration, watching his favorite movies on repeat, and reading. He had a special love for quarter-pounders from McDonald's, roast beef sandwiches from Lion's Choice, and crisp, cold Coca-Colas. Dennis cherished his family and friends from all over the world; he will be deeply missed. He is survived by his daughters, Charissa (Paul) Nelson and Melanie Jarvis, his grandsons Caleb Badger, Christian Badger, and Michael Nelson as well as his granddaughters Reagan and Jordan Nelson. Dennis was preceded in death by his father, Lynn Jarvis, and mother, Mary Kate (nee Burnett) Jarvis. A memorial service to honor Dennis's life will be held this summer, with details to be provided once plans are finalized. In lieu of flowers, contributions can be made to the Missouri Department of Conservation or the St. Louis Science Center in memory of Dennis Lynn Jarvis. Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. Phillippians 4:6-7
