Kaitlin Bacon

Kaitlin moved to the metro area in 2009 from northwest Oklahoma to attend the University of Oklahoma. It was in one of her general biology courses that she discovered her love for botany and plant life. She graduated with her bachelor’s degree in plant biology, with an emphasis in ecology. She has experience as an assistant in both the university’s herbarium and greenhouses, and she was the laboratory technician and later manager for the plant ecology lab at the Oklahoma Biological Survey, which specialized in prairie and grasslands ecosystems. Because of her ‘accidental discovery’ in college, Kaitlin is most excited to be a part of the Gardens because of what it is and means to those who, without them, might not have necessarily had the opportunities for such green immersion and discovery.

Paul Nehls

Paul grew up here in Oklahoma City, Oklahoma and has lived here his whole life. His first introduction to plants was with his grandmother in the vegetable garden. From then on, Paul has found a love and passion for all living things. Paul and his wife went through a transformative time in their life by taking care of his Grandmother while she was in her prime, her latter years of life. Now, he sees her in all things and will continue to pass her love on through his career and those around him. First starting out in garden centers, he learned fundamental plant care basics and management skills. Moving on to odd jobs, he found his life was missing something. So he pursued horticulture and went on to his own landscaping career, nurseries, greenhouses and the Oklahoma City Zoo. Paul will pass along a passion and love of horticulture and its fundamentals to the Oklahoma City public and all those around him. Horticulture and plants are so invaluable to all life on Earth, how can we not want to know more?
