I served as an officer in the United States Navy for 28 years, retiring in 2012.  During the latter part of my career I supported the Navy's efforts in network defense, as well as Science, Technology, Engineering, and Mathematics (STEM) outreach.  I have served as a mentor for high school teams competing in the CyberPatriot cyber defense competition and began my part-time career as a community college instructor in 2013.  I currently teach classes in Ethical Hacking and Linux.

I have been working in the computer technology field since 1985, when I started my professional career as a FORTRAN programmer, and would later program in C, C++, and Ada.  During the following years I transitioned to system administration of Linux systems and later to the integration of Automated Fingerprint Identification Systems.  I went on active duty with the Navy in 2002 to support the Certification and Accreditation of Navy and Marine Corps networks.  Since returning to my civilian career my focus has been on network security and penetration testing.


My primary hobby is the restoration of my 1971 Ford Bronco.
