This fascination with plants led him to leave the oil field and embark on a journey to receive a BS in Horticulture Sciences (Minor in Integrated Pest Management) from Oklahoma State University.

I will continue to do my part in keeping these gardens as one of, if not the most, beautiful areas in the entire metro,” said David.
