Ross Ohman

Environmental Technical Customer Services

I was born and raised in the Minneapolis area and I graduated from the University of Minnesota with a degree in Civil (Environmental) Engineering. I also have an MBA from the University of St. Thomas so I am both a GOPHER and a TOMMIE. I married a Wisconsin girl and we have three grown children who are all employed in science fields. When I met Mike and the team at IWS things really clicked as we share the same passion for helping clients by developing and implementing solutions to their (industrial waste, environmental, and safety) needs. I am grateful and excited to be working with such a wonderful team of awesome people!

Jerome Niss

Hazardous Waste Coordinator – OSHA Outreach Instructor

Jerome grew up on a small farm in Southern MN. Where we farmed the land, milked some cows, raised chickens, etc. Played sports in high school…. football, baseball, and wrestled. But the love of the outdoors was, and still is very important to me. I love to hunt deer with bow, hunt wild turkeys and waterfowl. But my passion is fishing, and it don’t matter if it’s on open water or on a frozen lake. I enjoy being on the water. In 1997, I met the love of life Kimberly. She is the Principal Director of Curriculum for the school district in Fairmont MN. We both love spending time together, along with traveling and spending time outdoors and taking in all that God has provided for us. I have over 40 years’ experience in manufacturing and managing their EHS departments. Taking care of OSHA and EPA Regulations for these companies has made me well rounded in all aspects of taking care of employer’s needs with training and managing of their waste. I truly love the engagement with all people from the janitor to the CEO. I have a unique talent to be able to relate to all employees.

Chris Emerson

OSHA Safety Compliance Consultant and Trainer

I was born and raised in Southeast MN area and I graduated from the University of Minnesota-Duluth with a degree in Biology and a Minor in Chemistry. I met my wife in Duluth, even though we grew up 15 miles apart but had never met! We have 2 school-aged children who are very active in multiple sports. I met Mike back in 2013 at the annual MN Safety Council Conference. We said we should connect again sometime, and in 2014 I started working for IWS, then fully into the ISG side of the business in 2015. Mike is very focused on helping clients by developing and implementing solutions to their (industrial waste, environmental, and safety) needs.
