My Role
I help my community with issues such as nuisance wildlife damage and management. I’m also proud of the work we’ve accomplished through the Master Gardeners program, as well as improving pecan and fruit trees and ornamentals in the county.
I think it is important to share the knowledge that educators have gained during our careers. For example, I’ve spent most of my working career in the horticultural field and co-owned/operated a retail garden center for 20 years. I also hold a Bachelor of Science degree in horticulture and a Master of Science degree in environmental sciences from Oklahoma State University.
