Holly grew up in the town of Fay, Oklahoma, a small town Northwest of Oklahoma City, graduating from Thomas-Fay-Custer High School in Thomas, OK. 

Holly attended Northwestern Oklahoma State University in Alva, OK where she graduated with a B.S. degree in Psychology.  

She began working for Sullivan Inc. in 1999 in Ulysses as scale help during wheat harvest in the summer.  Cowan didn't intend to stay but the harvest temp help position turned into a full time job and she became more involved in grain accounting, accounts receivable, and accounts payables. ​While she was growing up, Cowan's parents had operated a custom harvest crew and the family would travel from Texas to North Dakota every summer; an experience that made an impact on Cowan and would ultimately lead to her staying instead of pursuing other career paths.

Sullivan, Inc. was purchased by GCC in 2006 and the GCC Crop Production accounting responsibilities were also added to Cowan's list of assigned tasks. 

In 2019, Holly took over as the Human Resources and Administrative Services Manager upon the retirement of Caroline Duvall.  Her twenty previous years in the accounting department has given her a lot of experience with the co-op, particularly in grain and crop production accounting.  

Holly married her husband Daron, who also works in the ag industry, in 1998.  They live in Ulysses with one daughter, Lily.  

Holly is a coach for her daughter's Odyssey of the mind team, active in her 4-H projects and volunteers at her church.  She also enjoys cooking, shopping and home projects.  She will graduate with her Master's Degree in Industrial and Organizational Psychology from Kansas State University December 2019.  

Cowan states that the best part of working for the co-op is "The great people / coworkers and the farmers."

Michael Davis graduated from Southwestern Oklahoma State University with a Bachelors degree in Computer Science and a minor in Mathematics.  He then attended Texas A&M University's Master in Visualization Sciences program.
Michael began working with the Garden City Co-op in 2010 as the IT Developer. In 2016 he became the IT Manager where he and his staff are responsible for the current and future technological needs of the Co-op.
Michael resides in Scott City with his wife Alicia and three daughters, Payton, Piper and Preslee.  In 2025 he became GCC's IT Engineer, helping execute technology strategies and projects designed to help move our company forward in this fast paced technological age.
