A powerful and provocative speaker, Sidney has addressed audiences from a variety of domains across the world. Aviation, healthcare, nuclear power, oil & gas, process control, finance, the military — all have found that you might not agree with him, but that you cannot ignore him. Sidney alternately unites and divides his audiences. He works the room dynamically, intensively, unavoidably.

Please note that bookings are typically made a year or more in advance.
