We engaged Ellen Bessner to handle a complex shareholder dispute for our mid-sized company. Her 38 years of experience, particularly her recognized expertise in corporate and commercial litigation, were immediately evident. She provided clear, common-sense advice that cut through the legal complexities and helped us focus on our business objectives. Her tough-minded, strategic approach was exactly what we needed, and her background at prominent Bay Street firms gave us great confidence. While her billing structure is typical for her level of expertise, clearer upfront estimates would be helpful. Overall, her determination and practical guidance were instrumental in achieving a favorable resolution. We highly recommend her for serious commercial matters.
