Band 2 
Band 2 Steve Spiegelhalter
Steve Spiegelhalter leads Alvarez & Marsal’s North America investigations practice and has extensive expertise leading investigations that involve FCPA violations, money laundering, financial fraud, political corruption and other criminal matters. Sources point to his experience as a former prosecutor in the FCPA unit at the DOJ.
I love working with Alvarez & Marsal. The main reason I go to them is Steve Spiegelhalter. He is very efficient and very sharp. He is a former prosecutor and he has worked in-house. He has a great feel for what is important and what is wasteful and will cut to the chase to do investigations whilst remaining sensitive to what companies want. I found him tremendously valuable to have on the team.
