Grace Geils brings a strong scientific background and a lifelong connection to agriculture to her role at Planet Earth Agronomy. She holds bachelor’s degrees in Chemistry and Biology from the University of Wisconsin-Stevens Point, graduating in 2026.

Growing up on a farm in northeast Illinois, Grace developed an appreciation for agriculture at an early age and an interest in understanding the science behind successful crop production. Her education in chemistry and biology has provided her with a strong foundation for evaluating agricultural products and understanding the biological processes that influence plant health and performance.

Grace first joined Planet Earth Agronomy as an intern in 2024 while completing her studies. Following her graduation, she joined the PEA team full time in May 2026. In her role, Grace oversees field trials and laboratory testing, helping ensure that PEA products are thoroughly evaluated and meet the standards of quality and performance that farmers can rely on.

Grace’s combination of scientific training, hands-on agricultural experience, and familiarity with PEA’s research and product development makes her an important part of the team as Planet Earth Agronomy continues to evaluate and develop solutions for growers.
