Chief Operating Officer

Wipfli is assisting our client, SUL4R-PLUS with the recruitment and selection of a Chief Operating Officer (COO).

Established in 2013, SUL4R-PLUS is one of the leading fertilizer manufacturers servicing the agricultural industry with a proven, patented Calcium Sulfate nutrient. SUL4R-PLUS operates two established manufacturing facilities, in Louisville, KY and Marissa, IL, and is entering a pivotal stage of growth, both domestically and internationally.

SUL4R-PLUS is seeking a COO who will be responsible for overseeing the company’s manufacturing operations and is energized by the opportunity to help shape this next phase of expansion. The COO will report directly to the CEO and Owners and work side-by-side to influence major decisions, guide the evolution of the operational strategy, and build systems and structures that will carry the company into its next chapter.

The ideal candidate brings deep experience in fertilizer or bulk solids manufacturing and understands how to translate technical excellence into safe, reliable, and scalable operations. Equally important is a passion for mentoring teams, improving systems, and building facilities the right way — not simply managing what already exists.

The Chief Operating Officer will serve as a trusted operational leader, advisor, and strategic partner to ownership, with the authority to influence how plants operate today and how future facilities are designed, built, and commissioned.

This position is in-person and will be based out of their Louisville, KY or Marissa, IL locations.
