Nisus Corporation is proud to announce its transition to a 100% employee-owned company through an Employee Stock Ownership Plan (ESOP), effective April 30, 2026. As an ESOP-owned company, Nisus begins a new era focused on shared success, long-term stability, and continued innovation.
This milestone was made possible through the collaboration of Nisus executive leadership and the Dietrich family, whose vision and support helped guide the transition. Founded in 1990 by Bud and Pat Dietrich with the introduction of Bora-Care®, Nisus has grown into a trusted leader in pest control and wood protection while remaining grounded in its people-first culture and commitment to environmentally responsible solutions. On the family’s decision, Pat Dietrich said, “Bud and I have always loved the people who make Nisus work. This was the perfect way to recognize their hard work and loyalty, and to protect what makes Nisus so special.”
President and CEO Lee Barrett and CFOO Valerie Brummitt played key roles in bringing employee ownership to fruition. “Our founders believed deeply in investing in their employees, community, and industry,” said Barrett. “This transition reflects the culture of care and generosity they built and creates meaningful opportunities for the dedicated team members who drive our success every day.”
As employee-owners, Nisus team members will build ownership in the company through annual share allocations tied to their service and contributions.
Nisus was advised by AmbroseAdvisors, a national investment banking firm specializing in employee ownership transactions. Michael Harden, Senior Managing Director at AmbroseAdvisors, noted, “The Dietrich family sought a path that would preserve the company’s future while benefiting employees, customers, leadership, and the community. Employee ownership creates lasting value for all stakeholders, and we were honored to support this transition.”
“We are excited to continue the legacy Bud and Pat built,” said Valerie Brummitt. “This transition is about more than ownership — it strengthens the values, culture, and commitment that have defined Nisus from the beginning.”
Lee Barrett added, “We are incredibly proud of the work we do at Nisus and honored to carry forward the foundation the Dietrichs created. Employee ownership positions us to build an even stronger future and expand our impact across pest control, wood protection, and beyond.”
