I started my legal career in 1994 as a student at a full-service law firm in Toronto and as a young lawyer was quickly drawn to litigation. Developing my work as a civil litigator ever since, I have appeared with success at all levels of court in Ontario. Born and raised in Hamilton, it has been a pleasure to return my practice to serve the Hamilton community since 2009.
“Learning about, getting to the heart of, and appreciating the unique qualities each individual brings to the table, is important to me in all of my personal interactions with people. I am thankful for how our practice introduces me to new people with new experiences. I am fortunate to be able to learn from others while I advocate for them, so they can try to recover their best and unique selves as much as possible after dreadful accidents and losses.”
