5 out of 5 stars.

I cannot thank you enough for what you [Chris Collins] and Charlene [Howlett] have done for me! I was so wary and anxious about beginning the legal process, but you and Charlene expertly guided me through it all, every step of the way. Charlene’s timely, patient responses and quick results when dealing with my own insurance company were all truly amazing. Words cannot express how much I appreciate your kindness, thoughtfulness, patience and steady support when I felt so unsure and my head was spinning. The outcome was an amazing, surprise, surpassing my hopes. The timing couldn’t have been more perfect. From the bottom of my heart I thank you so very much! - C.E.

I am very thankful to have been represented by Marie [Tukara] in what started as a high conflict marriage separation. I wanted to fight back as hard as possible, but not compromise my own integrity and sense of fairness. Marie was the right lawyer for me, as her integrity and desire for fairness, especially with respect to the children, was in line with my own. I found her to be incredibly competent and efficient in synthesizing a complex story into a concise response for legal documentation. In short, with Marie I was able to neutralize a large amount of unfairness delivered my way without having to stoop to the other party’s level, which is what any self-respecting person would ultimately want from their lawyer in my position. - A.S.

When my husband and I bought a business, we chose Siskinds as we had a friend working there. Our purchase was relatively straightforward, and the lawyers involved gave us just the right amount of advice and legal support. They kept the amount of work inline with the size of our business, which was great. I'm giving four stars as our work wasn't complicated, but I wanted to say that you shouldn't be afraid of using a big firm like Siskinds for anything you need. -L.G.
