Sales West of the Mississippi
Keith Snider Sales Representative
Keith grew up on a cattle farm in southern Missouri and worked for a crop farmer when he was a teenager. In 1988 he started his own business as an agricultural land-leveling contractor. Keith’s experience in land leveling led him into the golf course building business in 1995. As a shaper, Keith helped build many championship golf courses across the country.
During the years spent working on golf courses, Keith learned about growing turf type grasses and the use of liquid fertilizers. This knowledge benefited him when his interests expanded into the agricultural side of the liquid fertilizer business.
Over the years, Keith has gained professional contacts across the nation, and these contacts have provided access to a wide variety of resources for testing, manufacturing, and consulting.
Keith joined PowerAG as a salesman in 2015 and services sales west of the Mississippi River.
