Kate Mazzucco

Kate’s practice in personal injury litigation is bolstered by her skill and attention to every detail in her clients’ cases.


Kate is a Partner on Patrick Brown’s team. She completed her undergraduate degree in Kinesiology at the University of Toronto and law degree from the University of Western Ontario. She was called to the Ontario Bar in 2007. Since being called to the bar, Kate has exclusively dedicated her practice to representing people who have been seriously injured or lost a loved one due to the fault of another. Kate’s education in kinesiology, and more specifically, her background in anatomy and physiology, gives her a better understanding of her patients’ injuries and impairments.

Before becoming a lawyer, Kate witnessed first-hand the devastating effects a car accident can have when a member of her family was seriously injured in a car accident. It was through this experience that Kate gained a personal appreciation for the importance of having skilled, knowledgeable, caring and compassionate legal counsel. The experience also gave Kate personal insight into the significant role a lawyer can play, not only in obtaining fair compensation for her clients, but in assisting her clients in their recovery. Through this experience and Kate’s education in kinesiology, personal injury litigation became the obvious career path.

Kate is a member of the Ontario Bar Association, the Canadian Bar Association, the Advocate’s Society and Ontario Trial Lawyers’ Association. Kate has been the vice-chair for the New Lawyers Division of the Ontario Trial Lawyers’ Association. Kate has prepared and presented papers for continuing legal education programs for lawyers, and for health care providers in Ontario. Kate worked with the Kids at Play organization to bring the Slow Down – Kids at Play campaign to Toronto’s east end communities. She has also been on the committee for the annual BIST Run, Walk and Roll for the past two years, and will be chairing the committee in 2017.

On the weekends Kate enjoys spending quality time with her husband and two children.
