I was involved in a MVA 5 ½ years ago. I had no clue what to do after the fact because of my injuries. Someone had referred me to Frank and Lesly to see if they could help me. And I am so greatfull I did. They took everything over, were able to get me all in home support, rehab etc. I would not be where I am today if it wasn’t for them. They were always there to answer my questions, time and time again when I couldn’t understand what was happening. Kathy always answering my emails to help me through all the process. They were always upfront and honest about what to expect, and what they could do to help me. If you are looking for an amazing legal team you have found it with them! – C.M.

My family engaged Tierney Stauffer LLP to handle a case of grave assault on my brother over 6 years ago. At a time where my entire family was engrossed in deep grief, this law firm represented by the duo of Susan Mitchell and Lesly Joseph were absolute rock stars. They guided us throughout, avoiding legal pot holes that could mar our case. As the other party tried to cause unnecessary delays, these lawyers persisted, using calculated pressures as the occasion demanded to press forward.

My family and I are extremely grateful and will always recommend these lawyers to anyone for these reasons:

    1. They were always within reach to tackle any questions we had about the case.
    2. Their genuine empathy and understanding of the grief the family was going through…this proved to be extremely important!!!
    3. Resisted in a subtle manner any attempts to prolong the case unnecessarily.
    4. Even after a settlement was reached, their long reach to the officers at Health Canada and other institutions helped us negotiate favourable terms.
    5. Their methodical approach to the entire case gave us a water tight schedule and a good understating of what to expect at each milestone
    6. Finally, both Susan Mitchell and Lesly Joseph exhibited great professionalism throughout the case.


Worked with Frank and Lesly and their team for almost 6 years. They made us feel we where their only clients with the level of service and compassion they provided. If we had any questions we always got our answers that promptly. Their ability to work with someone with a invisible disability and adapting to the persons needs was amazing. Totally recommend this law firm – D.C.

I couldn’t be happier with this law firm. Professional, Discrete, Understanding and Equitable. I dealt with Lesly Joseph who not only brings her professionalism, discreteness and positive attitude, but an amazing A-game to mediation. She took the time to explain the legal process to me and my family. She was clear on what we could expect from the entire process from start to finish. She prepared us well in advance and was accommodating over the course of the entire process. In the end, she reached a more than fair deal for us. The law firm had a few receptionists and clerks that I dealt with, and all of them were consistent in providing professional service and prompt responses via email, phone and even in person. I would definitely recommend them. Thanks Lesly! – R.S.

My life was completely and permanently altered after a car accident and a resulting traumatic brain injury. To my surprise my own insurance company tried to break me over and over and over again as did the lawyers for the defendant. Lesly Joseph of TS kept me informed and calmed and reassured me when I was about to give up. She always had time for me as did her paralegal. Lesly guided me through the whole process and obtained settlements for me beyond my expectations. And a huge relief was that I did not have to go to trial. Lesly is smart, competent, personable and I highly recommend her. Thanks Lesly! – K.G.

Lesly Joseph and Tara Renaud are very professional and quick to answer questions in a competent and efficient manner. They took the time to re-assure me and guide me through the process of my case. They also made sure I received reminders of the next steps and of what is required in order to keep my case ongoing. I would definitely recommend them to anyone needing legal assistance – R.F.
