Michael [Connell] was such an incredible help to us as we navigated a new situation in selling our income property. He spelled everything out for us so clearly and concisely and helped us understand complex legal documents and terms with ease. I would highly recommend him for his professional knowledge and expertise while having a personal touch that made us feel comfortable and took all the stress out of the process for us. Thank you Michael and Simone! - P.J.

I had a great experience with John Morrissey and his team at Siskinds. I was in a same sex common law relationship and required his help with a dependent support claim. John made my first time experience dealing with a lawyer an easy one. He was very knowledgeable and he and his law clerk Adam were always available to answer any questions or concerns I may have. I would highly recommend John and his entire team at Siskinds. - R.S.
