About
I have worked in Information Technology for 15 years, including varied environments such as high op-tempo shore and sea-based military units, traditional corporate environments, and the manufacturing industry. Since my career began in the US Navy, I have always operated as a security-minded technician, which is more important today than it ever has been! Aside from Information Security, I focus on quality of service, ensuring efficiency and transparency to users and stakeholders that I support.
