Accomplishments:
* Helped develop a cut flower

State University with Julie Sherk
during graduate school.

science: " In many ways, it was a long and hard five years. It
is difficult to see the end goal and even more challenging to
hope that you find a great and exciting job. Luckily, I did! "
* In 2022, took on leadership of the technical services team
at Ball.
A History of Horticulture:
Nathan started Nathan's Greenhouse with his dad in middle
school, the same dad that grew 6- to 7-foot cannas that
Nathan and his brothers used for playing ninja. Still today,
Nathan could garden and work in the yard all the time.
Goodbye, Reddi-wip:
He can't live without homemade whipped cream: " The stuff
from a can just doesn't cut it! "
Accomplishments:
* Received the Ornamental
Publication Award from the American Society for
Horticultural Sciences for " Reduction of Botrytis
Cinerea Infection on Petunia Flowers Following
Calcium Spray Applications. "
* Has helped grow Metrolina's test lab to identify crop problems.
* Completed her master's degree in plant and environmental
sciences at Clemson University. " It was a great privilege to
work with Dr. Jim Faust. "
Hot From the Oven:
In addition to gardening and reading, baking is one of
her favorite hobbies and forms of stress relief: " It is very
therapeutic for me. "
Golf in Their Blood:
Hall of Fame golfer Raymond Floyd gifted Katherine's
parents baby golf shoes when she was born. Her dad,
uncle and grandfather are/were all golf superintendents
and professionals.
