Who We Are

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

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

Mary Jane Barwick managed the daily operations of 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 joined the team to assume the role of office manager and is doing an amazing job.
