Sam D. Sitterle is President of Green Grow Organics. A 1987 graduate of the University of Texas with degrees in industrial engineering and marketing, Sam gave up a successful career in sales in 1991 in favor of a back-of-the-truck job in landscaping. Within a year, he was not only running his own crew but all others for the company. In 1991, in 2012, he founded Green Grow Organics after recognizing the need for a truly organic solution in landscape feeding and inoculation for South Central Texas.
