5 out of 5 stars.

I am certainly grateful for Jill McCartney and Madeline McKinnon for all the time they spent on the class action for my and many others issue. People like me do not understand all the legal procedures and get impatient but the team was there to answer any questions or concerns no matter how many times I called or e-mailed and encouraged me to do so . In the end Jill made sure I totally understood the decisions.  Thank you so much for caring. Would recommend this firm anytime. - F.A.

I am sincerely grateful to Leanne Kuchynski for representing my wife and I in what we considered to be an unprecedented situation. Leanne's compassion, practical advice, openness to feedback, brilliant strategic thinking and outstanding work ethic led to the most optimal outcome while maintaining a superior human experience. Despite the harsh realities of the situation, I felt extremely comfortable that our best interest was Leanne's utmost priority and was confident in her demonstrated ability. She was professional and exceptionally thorough, yet remained remarkably caring.

I use to have a somewhat cautious disposition towards lawyers based on past experiences; however, Leanne completely restored my faith in the profession and earned my unquestionable loyalty for all future legal needs. - S.M.

“Knowledge is Power” is the driving force behind Catherine Bruni’s style of defense. Over the past decade Cathy has represented our firm with much success; the key factor being that Cathy knows every detail of the case, not only from the defense perspective, but the plaintiff’s side as well. Understanding the case from every angle gives our team an advantage, resulting in very favourable outcomes. Cathy’s straightforward approach has earned our respect and created a relationship of trust and confidence. Litigation is a stressful experience that can take away from one’s ability to operate a business. With Catherine Bruni as our advocate, we can continue to focus on the success of our business knowing that Cathy is managing one of the more difficult aspects of our business’s exposures. - A.P.
