CEO & Executive Chairman

We live in interesting times. COVID-19 has reminded us of our vulnerabilities, and of the power and importance of science and technology in our daily lives. As a global supplier of equipment and technology used to develop solutions to the world’s greatest challenges, we have never felt a greater sense of responsibility to our clients and the billions of people around the globe they serve.

Solutions from Conviron and Argus Controls are being used extensively by scientists and pharmaceutical firms pursuing plant-based vaccines and therapeutics to defeat COVID-19 and other deadly diseases, like Ebola. Similarly, our equipment is being used in more than 90 countries to address the critical challenges of food shortage, food security and climate change. Thus, our mission, which states: “We contribute to feeding the world, improving human health and protecting the environment by providing technology that advances plant science and production,” has never been more relevant than it is today. It is why we are investing more in R&D than at any time in our history, and why we are expanding our service network to ensure our clients are fully equipped with the technology they need.

Our team is proud of what we do. Our Code of Conduct reflects our commitment and reminds each and every member of our team of the enormous responsibilities we have to science, our clients, our communities, our planet, each other and ourselves. Most of all, we are proud of our association with our thousands of clients who dedicate themselves to making all of us safer, healthier and happier. For this we are grateful.
