Cary Rivard was born and raised near Kansas City, Missouri, where his family owns and operates a small, retail greenhouse business. It was here that he first became interested not only in propagation and greenhouse management, but also learning and teaching about plants.

He received his B.S. in agricultural sciences and biology from Truman State University in Kirksville, Missouri. He completed his M.S. and Ph.D. in plant pathology at North Carolina State University as a member of the Integrated Disease Management Lab. Rivard's graduate research was focused on tomato, but as a student he also worked with several crops, including strawberry, pepper, tomato, and cucurbits, and has experience working and conducting research in high tunnel production systems.

Rivard is excited about the opportunities to provide support for local food networks and develop an applied research program that will help to promote local fruit and vegetable production. "As a native of the Midwest, it’s important to me that we continue to expand fruit and vegetable production in this area. I look forward to the opportunity to provide support in this effort and assist with the development of effective production practices for the region."
