Our company history

Grown from the ground up

Central Ag Supply Inc. started in a 1 car garage with 1 employee serving less than 100 customers. South Central Dairy Supply, Inc. started in a small pole shed and chicken coop serving less than 65 customers. Both dealerships have been dedicated to serving the dairy industry for over 25 years.

Merged Central Ag Supply Inc. company was established March 1, 2016

These two professional and dedicated businesses merged for the benefit of our customers and employees. Now employing over 30 people between both locations and regularly serving over 600 customers across Wisconsin's South Central and Eastern dairy land and beyond. It is our commitment and privilege to serve the needs of the dairyman.

We embrace the opportunity to contribute to the future success of all of our customers from both locations.
