ChicagoFIRST welcomes incoming Board Member Walter Lefmann
Walter Lefmann is currently Director of Security at CTC Trading Group LLC, an options market-making firm. His role comprises Information Security, Physical Security and Life Safety, and BCP/DR. Prior to CTC, Walter had various roles at Goldman Sachs, Hull Trading Company, and Motorola. He began his career as an experimental physicist at the Fermi National Accelerator Laboratory. Walter holds a PhD, MPhil, and MA in Physics from Columbia University, and a BS in Physics from Stevens Institute of Technology.
While at Columbia University, Walter also served for five years as a volunteer NYC Auxiliary Police Officer and Sergeant. The experience of working closely with the public sector to serve and improve the community was tremendously rewarding and has shaped a lifelong respect for the dedicated people who face the challenges of that service.
Walter participates in many professional and public/private outreach organizations, including InfraGard (for which he is a Board member), USSS Electronic Crimes Task Force, FS-ISAC, the National Technology Security Coalition, and ASIS.
Walter has been an active member of ChicagoFIRST for many years, carrying membership across transitions through several firms, and is excited for the privilege to give back and serve the organization.
