I just want you all to know how amazed and appreciative I am to have [Rasha El-Tawil and her team] in my recovery! You absolutely picked the right line of work! Thank you all so very much because I've come a long way and couldn't have done it without a fantastic team!!! - M.

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.

Everything that I was looking for help with [Maciek Piekosz] tried or was able to get for me. He fought for me. I am happy with him being my lawyer. He speaks my language (Polish) which made it easy for me to communicate with him. I would recommend to everybody if they need help after an injury that they use him. The rest of his staff cared, were diligent with communication and making me stay on top of tasks. - A.S.
