More About Timothy


Tim has worked for organizations of all types and sizes, from a large ISP to a development bank to Silicon Valley start-ups. Even when his job title has indicated otherwise, Tim has always focused on improving the security posture of his employer.

Tim's addiction to SANS training began after he attended his first course in 2003. "It was the caliber of the instruction and the real-world skills that could be immediately applied when I returned to work", he explains. Tim currently holds a CISSP-ISSMP and 12 GIAC Certifications including the highly regarded GIAC Security Expert (GSE #191).

Tim is one of the very few individuals to have achieved the distinctive title of SANS Cyber Guardian for both the red team and the blue team. He is also a member of (ISC)2, the SANS/GIAC Advisory Board, and acts as a subject matter expert and quality assurance tester for SANS OnDemand. "I have a passion for learning and love to share my knowledge with others", Tim says. "I am really fortunate that SANS values my knowledge and allows me the opportunity to share it."
