Witt O'Brien's Joins Ambipar Response Group: Expanding Global Reach and Enhancing Resilience Services


We announced in October 2022 that Witt O’Brien’s is now part of the Ambipar Response group of companies.

Ambipar Response is a public company traded on the New York Stock Exchange under the symbol AMBI. It is a leading provider of emergency management, industrial services, and environmental solutions, serving clients through 217 locations in 16 countries.

Like Witt O’Brien’s, Ambipar Response is a mission-driven organization, helping companies and communities become more resilient and sustainable. Our cultures, client solutions, and business models are highly complementary. Witt O’Brien’s continues to operate with no changes to its client service teams or contractual arrangements, thus ensuring a smooth transition for its customers. Through this combination, we are already broadening the solutions we offer our clients.

“This acquisition is transformational for Ambipar Response,” says Guilherme Borlenghi, Ambipar Response’s CEO. “The addition of Witt O’Brien’s broadens our portfolio to include over 11,000 clients across six continents. As governments and businesses struggle to address transformational challenges, we are well positioned to expand in this growing global market.”

Should you have any questions about this news, please reach out to your usual Witt O’Brien’s contact or myself. We thank you for the trust you have placed in our team and look forward to helping you achieve your mission-critical objectives.
