Dr. Clint Mattox

Dr. Clint Mattox graduated from Purdue University with a turfgrass science degree in 2000 and has been involved in the turfgrass industry since that time. From 2000 until 2012, Clint worked overseas, primarily in Europe, where he was an assistant superintendent in Berlin, head greenkeeper at Paris Disneyland, and finally grow-in and maintenance superintendent at the Arnold Palmer designed Vignoly golf course near Paris. In 2013, he began graduate studies at Oregon State University focusing on managing turfgrass diseases in the absence of fungicides. He finished a doctorate degree in March 2020, majoring in Horticulture with a minor in Botany and Plant Pathology where he focused on managing the turfgrass disease Microdochium patch in the Pacific Northwest using alternatives to traditional fungicides.
