About the Founder

“Crimetime” is the bestselling memoir of our founder, Mark van Leewarden—chronicling his undercover life and journey to becoming one of the world’s most successful fraud investigators.

“We’ve worked with Warden Consulting on a continuing basis for more than twenty years. They’ve supported us across multiple parts of the business nationwide, and the value delivered has been many times the cost of engagement.”
