MEET  THE  TEAM

In order to fully know and understand who we are as a team, you must first get to know and understand Greg. Greg worked side by side with his wife, Tara, to start and develop Valley Ag Supply into the business it is today. He was a great leader that taught, mentored, and coached his employees, but at the same time gave them great responsibilites to handle and learn things on their own. This great leadership set the foundation of who Valley Ag Supply is as a team that allowed them to carry on the legacy that he started. He was a great husband and father, a well respected person in the community and had a huge passion for agriculture. He will be sorely missed.
