Who We Are

DARO Commodities Inc was started by two brothers: David and Ronnie Lucio in 1976, thus the acronym DARO. They first sold feed commodities, then branched out into fertilizers.

About 1987 they hired Tim Geary and Skip Barwick to run DARO to further expand the business. Over the years DARO product lines increased, Skip became a partner, and eventually purchased the business. The company eventually dropped the feed lines of commodities and went strictly into soil amendment sales.

Mary Jane Barwick ran the office. Corbin Prine was hired in 2015 to learn under Tim who had become an industry legend due to his passion for service. In 2016, Lydia Cota was brought on to eventually assume the role of office manager and is doing an amazing job.
