Kelli Rodda, Editorial Director
As editorial director of the GIE Media Horticulture Group, Kelli seeks out and delivers essential information to help green-industry businesses improve their bottom line. She’s visited several hundred nurseries and greenhouses — from mom-and-pops to massive operations — across the United States. She’s also seen some of the most high-tech operations in Holland.
She resides in Azle, Texas, with her husband Jason and daughter Molly, as well as a gaggle of pets. She sometimes bewilders her GIE Media coworkers, who are based in Ohio, with her odd Southern expressions. She enjoys container gardening and blurring the Hardiness Zones by experimenting with lots of plants. Her favorite plants: the American sweetgum (Liquidambar styraciflua); Salvia sp.; and Viola tricolor. She also enjoys spending time in the mountains and the forest.
Kelli is proud to represent an industry that characterizes hard work, integrity and professionalism. She enjoys being part of an industry responsible for products that do so much for human nature and the environment.
She’s been a professional journalist for three decades, specializing exclusively in business-to-business publications. Reach Kelli by email here.
