I wholeheartedly endorse Joe for any environmental needs you have.

Joe Maternowski prevails on APO
Joe Maternowski was referred to me to represent our company in an Administrative Penalty Order. I quickly learned how familiar Joe was with the APO process and how he would best represent us. Ultimately we received a favorable decision from the administrative law judge to have our APO dismissed. Joe did an extraordinary job representing us and helping us to navigate our way through a long and difficult process. Many thanks go out to Joe and his staff of Hessian & McKasy, P.A.

Sale of environmentally sensitive assets
We had the task of selling a facility with an existing air permit in Minnesota that we had constructed and intermittently run for one year. The buyer had one of the nation's largest in-house environmental teams and dedicated their team as well as prominent environmental lawyers to this asset purchase. We hired Joe to be our leader on all environmental issues because of his reputation and history of working with the Minnesota Pollution Control Agency. During the three month due diligence process, the issues expanded from the air permit to EPA issues and Joe led all of our negotiations with the buyer's team. We had a successful transaction outcome due, in large part, to Joe's knowledge and communications and negotiating skills.

Kansas Property Manager thrilled with Joe Maternowski's representation
Joe Maternowski was able to reduce the proposed EPA fines by almost 98% with his professional research, hard work, attention to detail and thoroughness. We could not have done it without the aid of his sound legal advice. I cannot imagine a kinder, more able attorney. He bridged the gap between Minneapolis and Kansas with no communication issues.

A "Go To" Guy
I have Joe Maternowski to assist me when legal issues arose over the past 10 years. In that time I have found Joe Maternowski to be extremely helpful in solving what I knew were highly complex problems involving my medical practice. Initially, he provided assistance on resolving mold issues that affected our commercial office space. Over the years my trust in Joe grew and I asked for solutions in a buy and sell quandary that our office faced. Joe quickly sought other experienced colleagues for Moss & Barnett and he oversaw the completion of this matter in an expeditious manner. I consider Joe to be a "go to" guy. He demonstrated his professionalism in handling the ongoing challenges of considerable medical/ legal problems that our office faced. I recommend Joe Maternowski and his colleagues at Moss & Barnett highly to my friends and associates.

Attorney for our company against the Federal EPA
Our company worked with Joe over two years to resolve a complaint from the Region 5 EPA. Joe went out of his way when the EPA inspector arrived at our facility unannounced and worked several days over a holiday weekend. He was always quick to respond to questions and represented our company well.

Joe Maternowski is an effective, talented and dedicated attorney
Joe and his colleagues represented me in an employment law case. They were quick to review all the materials, make an assessment, discuss my options with me and make their recommendations. Joe and his colleagues listened to my concerns with great interest and helped me see what the most effective strategy might be. There was definitely give and take and I really appreciated that. At the end of our discussions, we reached a mutually agreeable solution. Joe was also very fair and reasonable in his billing. I felt I got my money's worth. I have also consulted Joe on other issues informally over the years. He is extremely approachable, knowledgeable and reasonable in his analysis of issues. I would highly recommend him and his firm to anyone.
