Marvin Wastell founded Gro Master in 1982 to bring his expertise in nutrition, consultation and formulas to livestock and poultry producers. In the late 1980s, Marvin focused his efforts on developing and marketing a newly patented wet/dry hog feeder in the United States. Today our team is actively addressing equipment needs, educational activities and strategies to fill voids caused by shortages of labor and to reallocate quality employees for greater impacts.
