Joe Gaynor is an awesome lawyer. He ticks all the boxes of what an outstanding lawyer should be. With empathy and compassion he made the decisions that were right for me. Thanks. All the best to you and your team in the future. - D.C.

…I always tell people about Siskinds and what a great team especially Christina Martin were, as well as my adjuster, and rehab team. Couldn’t be where I am today if it was not for you! – R.X.

I want to thank Andrea [Cooley] so much for all her care, concern, work, expertise and wisdom that she gave over the last few months. A separation is something I did not really want to go through, but with Andrea's help I am thankful that I was able to get it all figured out and finished up. I am very happy that it is done, and I can move forward. - L.D.
