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.

We are not a business or corporation, simple private citizens. After Joe was kind enough to listen to our issues ,he elected to help us with our personal issues. Couldn't ask for more professionalism, team work, compassion from him and his team.. Total joy and pleasure to have had the experience.

The attorneys at Hessian & McKasy helped me on Trusts and Estates matters. The firm set up a plan for my parents Estate. I served as Executor and the firm helped me at every step of the way distributing assests to beneficiaries and advising on tax matters. The attorneys at Hessian and McKasy are efficient, timely, thorough and a pleasure to work with. I highly recommend this Firm for Trust & Estates matters.

Joe Maternowski is an excellent environmental attorney! He is knowledgeable in Minnesota regulations and voluntary programs and has great instincts. He communicates well and collaborates with consultants and stakeholders to ensure everyone understands their risk and options. I highly recommend Joe for real estate environmental legal work!

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.
