Justin Agee

Field Technician, SoilKeepers

Born and raised in a small town in Missouri, Justin has always had a love for the outdoors and adventure. This love turned into a passion for worldwide experience and knowledge, which led Justin on a journey of military service for nine years, during which he worked as a military intelligence electronic warfare specialist (electronics geek), providing him the opportunity to travel to many of the 50 states, as well as internationally to South Korea, Iraq, Kuwait, Qatar, and other undisclosed locations. Upon completion of service, Justin pursued his dream of becoming a fisheries biologist. He earned a BS in Biology with an emphasis in Fish and Wildlife Management from Augusta State University in Georgia in 2011, then found himself on many fishing boats in and around Alaska working for the National Marine Fisheries Service. After that experience, Justin’s persistent endeavor for knowledge, education, and adventure led him to Virginia, where he wants to spread the love, knowledge,  and appreciation of the outdoors.
