Aaron launched a business in solar grazing, blending innovation with agricultural stewardship. This entrepreneurial experience led him to join Soilworks, where he deepened his commitment to regenerative agriculture. Today, Aaron works in mergers and acquisitions, specializing in identifying and structuring investments that empower producers by making regenerative practices more profitable and scalable. Together with his wife and two children, Aaron raises Dorpers south of San Antonio using an intensive rotational grazing system.
