“On May 7, 2011, I was involved in a motor vehicle accident. I was originally told my injuries were minor and to go on with my life. Months later, after being properly diagnosed, I realized I needed to hire legal representation. An acquaintance recommended a law firm in the Windsor area. After having retained them, months went by without any updates or contact from them. Having never gone through this before, I wasn’t sure if this was “normal” practice. The only advice I ever received from them was to listen to my insurance company. That was a mistake! In August 2012, a good friend inquired about how things were going. After explaining what was going on, she recommended I get a second opinion. That’s when I contacted William Simpson at Lerners in London. After my very first meeting, I knew I was in the right place. William quickly identified key points that had not been addressed by my previous lawyer and put a plan in place immediately. I received continual updates on how my file was progressing and some much needed assistance with my own insurance company. Fourteen months after retaining William Simpson, my file was settled without the need for a trial. I am content with the results and would recommend William Simpson to anyone who’s been injured and needs a great lawyer to fight for them. Thanks to William and his team for their hard work!”

“I have dealt with William on the other side of cases as legal counsel. I was greatly impressed by William’s devotion to his clients and his vigorous representation of their interests. I would strongly recommend William to any person who has sustained an injury in an accident.”
George Tsakalis, Lawyer, Brown and Korte Barristers

“While working with William over the past few years I have come to appreciate his dedication, honesty, and professionalism. He is a genuine and capable representative who showcases not only his legal skills and talent, but also his moral character, within every interaction. William’s personal approach to sensitive legal matters sets him apart from his peers and I would highly recommend his work to anyone in need of strong and diligent representation. His staff is equally commendable – clearly from working under great leadership.”
Erin Foley Pitman, Platform Support Specialist, Thomson Reuters

“William has represented a number of my clients who have been involved in motor vehicle accidents, navigating the complexities of the Accident Benefits claims process, as well as through civil suits, if required. Each and every one of my clients has indicated to me that they appreciate William’s approachability, honesty and legal knowledge, along with the high level of support provided by his law clerks. William has consistently acted as an advocate for his clients to help them obtain the services, support and funding that they require to recover from and move past a traumatic event such as an MVA. Having a skilled legal representativecan make a big difference, and William consistently demonstrates his ability to be one of the best.”
Melissa Knott, Occupational Therapist, Pursuit Health Management

“We found Bill, Karen and Kristen to be very knowledgeable and helpful in seeking an insurance settlement following a vicious dog attack. Another law firm wasn’t willing to help unless we could determine if the dog owner had insurance, but Lerners offered their expertise to sort all that out from their end. From that point on, they took care of all the necessary steps to obtain an appropriate settlement. We are grateful for their expertise and highly recommend their firm.”
C. W., Chatham, Ontario

“In 2019, I turned to Lerners for advice regarding a car accident that injured me.  After a very straightforward and “to the point” conversation, I hired Bill Simpson and his team, including Kristen Gardiner, Christine Gould and Tanner Nesbitt.  They got straight to work and went to bat for me day in and day out. Bill fought tooth and nail for me so that I could recover from my injuries and focus on taking care of what is most important – myself and my family.  The communication amongst Bill’s team is spectacular and they are always there if you have any questions. I could not ever thank Bill and his team enough for everything they have done for me over the years. I highly recommend Lerners (especially Bill and his team). Thank you so very much Bill, Kristen, Christine and Tanner!”
