During her time in law school, Michelle interned with Legal Aid Cambodia – a non profit organization dedicated to providing legal services for low income communities.

Michelle worked predominantly with women and advocated for an end to violence against women, sexual tourism and sexual assault. Michelle also summered at the Human Rights Legal Support Center in the legal department by assisting persons who faced discrimination contrary to the Ontario Human Rights Code.

Lucas Jack-Sadiwnyk

Student-at-Law

I am an articling student at Mattis Law tasked with performing research, making court appearances and meeting with clients. I received my juris doctor from the University of Melbourne in Australia and my undergraduate degree in Philosophy from Trent University in Peterborough, Ontario. Before this I worked in heavy duty construction for a number of years and I worked on my father’s farm.

I am working towards becoming a lawyer because I have always had an interest in criminal law and helping people at a time in their life when they need it. My top accomplishment so far is being given the opportunity to actually participate in the legal system. At Mattis Law, even as a student-at-law you are expected to be an active part of the legal team. For example, one occasion when I met with a client in custody at the courthouse, then spoke to the Crown about having his charges dropped. The Crown agreed and I personally spoke to the matter in court. I also enjoy the research part of the job, criminal law is a complex subject and there is always something new to learn.

Outside of work I am on my way to becoming an officer in the Canadian Army involved with the Argyll and Sutherland army cadet unit in Hamilton, Ontario. I play guitar and enjoy being physically active.
