Roy Oommen

Senior Chemical Engineer

Most of us come into this profession with a healthy sense of idealism, wanting to make a positive contribution to the environment. Looking back at the last 25 years, I can honestly say that what we do at ERG has made a difference. Sometimes small, sometimes big, but always positive. The type of work we do matters to the environment. I am fortunate to be working with people who genuinely care about doing good and doing a good job.
