Minnesota - Minneapolis
Trinity's Minneapolis/St. Paul office, located in Oakdale, Minnesota, opened in 2005. Our managers in the Minneapolis office have combined experience of over 25 years serving clients in Minnesota and neighboring states (Wisconsin, North Dakota, and South Dakota). We have a strong relationship with the Minnesota Pollution Control Agency (MPCA) and interact with them regularly through Air & Waste Management events in addition to our normal project work. We are also members of the Minnesota Chamber of Commerce Environment and Natural Resources Policy Committee, and meet with the MPCA managers, various industries, and consultants to discuss environmental issues. We supported the opening of our Milwaukee, Wisconsin office in 2018 and work closely with that team to support projects in Wisconsin.
