Thank you Anna and staff. Yesterday was exhausting as you said but it was also interesting to watch the whole process. It was also refreshing to see such strength , kindness and compassion on your part in what looks to be a very harsh, ruthless environment. Thank you for your perseverance throughout the day to reach the best deal for M. that you could under the circumstances. It is a relief to know that this part of the process is over and that he now has a much better chance of securing a peaceful life. - J.

As the COO of a midsize company I contacted Siskinds with regards to an intricate and somewhat challenging H.R. issue, and we were directed to Christopher Sinal. Upon review of this complex situation, his in depth knowledge of H.R. law allowed us to construct a clear and strategic plan. Phone calls and email enquiries were dealt with efficiently and timely. Chris displayed his competency and confidence in our final negotiations to bring closure to the case. We appreciate his preparedness and professionalism in representing our firm. - B.D.
