  • It has been our pleasure to work with Mike McArthur from MHN Lawyers to advance our system of services for adults with a dual diagnosis. Mike's commitment to this population and his volunteer involvement with our network is an exceptional example of professionals, agencies and communities working together to address pressing community needs.

  • I have known Mike McArthur for several years, in his role as a lawyer in Simcoe, as an owner in Long Point EcoAdventures, an owner in Burning Kiln Winery and as Chair of the Board of Directors of the Ontario South Coast Wineries and Growers Association. In these capacities, Mike has provided excellent knowledge and experience to those who have worked with him. In addition, Mike is passionate about civic engagement and leadership, the development of new opportunities that benefit many stakeholders and the overall position of Norfolk and Elgin counties in the Ontario landscape. It is indeed my pleasure to provide a resounding endorsement of Mike McArthur and the programs that he is involved with.

  • Seeking legal advice may come across very intimidating, but at MHN Lawyers they will treat you with respect and efficiency. Paul Hosack has been representing me since my auto accident in 2010. He was recommended after another personal injury lawyer informed me that I didn't have a case. With Paul's years of experience, it has enabled him to provide thoughtful, thorough, and most importantly, a productive result. His law clerk, Amy Hofstetter, is outstanding. Her attention to detail is astonishing. She is efficient, experienced and compassionate. Wendy Wozniak is Paul's litigation assistant. Once more, Wendy is valuable, productive, cordial and committed. Paul and his staff have made an unpredictable life changing occurrence more comforting and satisfying.
