Donald T. Pine, President
November 2014

In May, we announced the retirement of Dave Ouellette, after 37 years of service to Chemtan. Dave began his career as a co-op student from North Eastern University at Chemtan. He worked his way up through the ranks, ultimately serving as VP of R&D and then President of the company, where he served for the past 6 years.

Sadly, Dave passed away in late September after struggling with cancer for nearly three years. It is a battle he fought valiantly, supported by family and friends. Most important for us is the remembrance of how he lived his life to the fullest every day. Dave was known the world over in our business circle foremost, as a gentle, kind man; and within Chemtan, as a person who possessed a strong work ethic, an ability to focus and solve the important challenges we faced as a company, under his leadership.

As a result of much planning and fore thought, together with Dave and the company board of directors, a succession plan was formulated and executed, as time and circumstances dictated. So fortunately, we were not completely unprepared.

I am proud to say, the people of Chemtan have weathered the difficulties faced from losing someone so integral to our business, by continuing to grow and evolve in our daily tasks, meeting the needs of our customers and reaching further, beyond where we were as a company.

We are thankful each and every day we awake in the morning for the opportunities we have, made possible by our customers and the people who work within Chemtan.
