  • 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.
