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.

Maciek [Piekosz] has been a great help and very accommodating since day one. He relays information in an understandable and clear manner. All correspondence with both him as well as other Siskinds personnel has been nothing but smooth and attentive. Thank you. - M.D.

I felt really safe knowing you [Daniel Hynes] were looking after my interests. I felt like you had my back. You were very professional, kind and caring, and I was very happy with how you handled everything.  –G.A.
